28 April 2017: mitmproxy 2.0.2
* Fix mitmweb's Content-Security-Policy to work with Chrome 58+
* HTTP/2: actually use header normalization from hyper-h2
15 March 2017: mitmproxy 2.0.1
* bump cryptography dependency
* bump pyparsing dependency
* HTTP/2: use header normalization from hyper-h2
21 February 2017: mitmproxy 2.0
* HTTP/2 is now enabled by default.
* Image ContentView: Parse images with Kaitai Struct (kaitai.io) instead of Pillow.
This simplifies installation, reduces binary size, and allows parsing in pure Python.
* Web: Add missing flow filters.
* Add transparent proxy support for OpenBSD.
* Check the mitmproxy CA for expiration and warn the user to regenerate it if necessary.
* Testing: Tremendous improvements, enforced 100% coverage for large parts of the
codebase, increased overall coverage.
* Enforce individual coverage: one source file -> one test file with 100% coverage.
* A myriad of other small improvements throughout the project.
* Numerous bugfixes.
26 December 2016: mitmproxy 1.0
* All mitmproxy tools are now Python 3 only! We plan to support Python 3.5 and higher.
* Web-Based User Interface: Mitmproxy now offically has a web-based user interface
called mitmweb. We consider it stable for all features currently exposed
in the UI, but it still misses a lot of mitmproxys options.
* Windows Compatibility: With mitmweb, mitmproxy is now useable on Windows.
We are also introducing an installer (kindly sponsored by BitRock) that
simplifies setup.
* Configuration: The config file format is now a single YAML file. In most cases,
converting to the new format should be trivial - please see the docs for
more information.
* Console: Significant UI improvements - including sorting of flows by
size, type and url, status bar improvements, much faster indentation for
HTTP views, and more.
* HTTP/2: Significant improvements, but is temporarily disabled by default
due to wide-spread protocol implementation errors on some large website
* WebSocket: The protocol implementation is now mature, and is enabled by
default. Complete UI support is coming in the next release. Hooks for
message interception and manipulation are available.
* A myriad of other small improvements throughout the project.

24 July 2015: mitmproxy 0.13
* Upstream certificate validation. See the --verify-upstream-cert,
--upstream-trusted-cadir and --upstream-trusted-ca parameters. Thanks to
Kyle Morton (github.com/kyle-m) for his work on this.
* Add HTTP transparent proxy mode. This uses the host headers from HTTP
traffic (rather than SNI and IP address information from the OS) to
implement perform transparent proxying. Thanks to github.com/ijiro123 for
this feature.
* Add ~src and ~dst REGEX filters, allowing matching on source and
destination addresses in the form of <IP>:<Port>
* mitmproxy console: change g/G keyboard shortcuts to match less. Thanks to
Jose Luis Honorato (github.com/jlhonora).
* mitmproxy console: Flow marking and unmarking. Marked flows are not
deleted when the flow list is cleared. Thanks to Jake Drahos
(github.com/drahosj).
* mitmproxy console: add marking of flows
* Remove the certforward feature. It was added to allow exploitation of
#gotofail, which is no longer a common vulnerability. Permitting this
hugely increased the complexity of packaging and distributing mitmproxy.
3 June 2015: mitmproxy 0.12.1
* mitmproxy console: mouse interaction - scroll in the flow list, click on
flow to view, click to switch between tabs.
* Update our crypto defaults: SHA256, 2048 bit RSA, 4096 bit DH parameters.
* BUGFIX: crash under some circumstances when copying to clipboard.
* BUGFIX: occasional crash when deleting flows.
18 May 2015: mitmproxy 0.12
* mitmproxy console: Significant revamp of the UI. The major changes are
listed below, and in addition almost every aspect of the UI has
been tweaked, and performance has improved significantly.
* mitmproxy console: A new options screen has been created ("o" shortcut),
and many options that were previously manipulated directly via a
keybinding have been moved there.
* mitmproxy console: Big improvement in palettes. This includes improvements
to all colour schemes. Palettes now set the terminal background colour by
default, and a new --palette-transparent option has been added to disable
this.
* mitmproxy console: g/G shortcuts throughout mitmproxy console to jump
to the beginning/end of the current view.
* mitmproxy console: switch palettes on the fly from the options screen.
* mitmproxy console: A cookie editor has been added for mitmproxy console
at long last.
* mitmproxy console: Various components of requests and responses can be
copied to the clipboard from mitmproxy - thanks to @marceloglezer.
* Support for creating new requests from scratch in mitmproxy console (@marceloglezer).
* SSLKEYLOGFILE environment variable to specify a logging location for TLS
master keys. This can be used with tools like Wireshark to allow TLS
decoding.
* Server facing SSL cipher suite specification (thanks to Jim Shaver).
* Official support for transparent proxying on FreeBSD - thanks to Mike C
(http://github.com/mike-pt).
* Many other small bugfixes and improvemenets throughout the project.

* Configuration files - mitmproxy.conf, mitmdump.conf, common.conf in the
.mitmproxy directory.
* Better handling of servers that reject connections that are not SNI.
* Many other small bugfixes and improvements.
15 November 2014: mitmproxy 0.11.1:

* Data streaming for response bodies exceeding a threshold
(bradpeabody@gmail.com)
* Ignore hosts or IP addresses, forwarding both HTTP and HTTPS traffic
untouched
* Finer-grained control of traffic replay, including options to ignore
contents or parameters when matching flows (marcelo.glezer@gmail.com)
* Pass arguments to inline scripts
* Configurable size limit on HTTP request and response bodies
* Per-domain specification of interception certificates and keys (see
--cert option)
* Certificate forwarding, relaying upstream SSL certificates verbatim (see
--cert-forward)
* Search and highlighting for HTTP request and response bodies in
mitmproxy console (pedro@worcel.com)
* Transparent proxy support on Windows
* Improved error messages and logging
* Support for FreeBSD in transparent mode, using pf (zbrdge@gmail.com)
* Content view mode for WBXML (davidshaw835@air-watch.com)
* Better documentation, with a new section on proxy modes
* Generic TCP proxy mode
* Countless bugfixes and other small improvements
* pathod: Hugely improved SSL support, including dynamic generation of certificates
using the mitproxy cacert
7 November 2014: pathod 0.11:
* Hugely improved SSL support, including dynamic generation of certificates
using the mitproxy cacert
* pathoc -S dumps information on the remote SSL certificate chain
* Big improvements to fuzzing, including random spec selection and memoization to avoid repeating randomly generated patterns
* Reflected patterns, allowing you to embed a pathod server response specification in a pathoc request, resolving both on client side. This makes fuzzing proxies and other intermediate systems much better.
28 January 2014: mitmproxy 0.10:
* Support for multiple scripts and multiple script arguments
* Easy certificate install through the in-proxy web app, which is now
enabled by default
* Forward proxy mode, that forwards proxy requests to an upstream HTTP server
* Reverse proxy now works with SSL
* Search within a request/response using the "/" and "n" shortcut keys
* A view that beatifies CSS files if cssutils is available
* Bug fix, documentation improvements, and more.
25 August 2013: mitmproxy 0.9.2:

* Don't take minor version into account when checking for serialized file
compatibility.
* Fix a bug causing resource exhaustion under some circumstances for SSL
connections.
* Revamp the way we store interception certificates. We used to store these
on disk, they're now in-memory. This fixes a race condition related to
cert handling, and improves compatibility with Windows, where the rules
governing permitted file names are weird, resulting in errors for some
valid IDNA-encoded names.
* Display transfer rates for responses in the flow list.
* Many other small bugfixes and improvements.

match asset flows (js, images, css).
* Follow mode in mitmproxy ("F" shortcut) to "tail" flows as they arrive.
* --dummy-certs option to specify and preserve the dummy certificate
directory.
* Server replay from the current captured buffer.
* Huge improvements in content views. We now have viewers for AMF, HTML,
JSON, Javascript, images, XML, URL-encoded forms, as well as hexadecimal
and raw views.
* Add Set Headers, analagous to replacement hooks. Defines headers that are set
on flows, based on a matching pattern.
* A graphical editor for path components in mitmproxy.
* A small set of standard user-agent strings, which can be used easily in
the header editor.
* Proxy authentication to limit access to mitmproxy
* pathod: Proxy mode. You can now configure clients to use pathod as an
HTTP/S proxy.
* pathoc: Proxy support, including using CONNECT to tunnel directly to
targets.
* pathoc: client certificate support.
* pathod: API improvements, bugfixes.
15 May 2013: pathod 0.9 (version synced with mitmproxy):

* pathoc -T option, instructs pathoc to ignore timeouts.
* pathoc -o option, a one-shot mode that exits after the first non-ignored
response.
* pathoc and pathod -e option, which explains the resulting message by
expanding random and generated portions, and logging a reproducible
specification.
* Streamline the specification langauge. HTTP response message is now
specified using the "r" mnemonic.
* Add a "u" mnemonic for specifying User-Agent strings. Add a set of
standard user-agent strings accessible through shortcuts.
* Major internal refactoring and cleanup.
* Many bugfixes.
22 August 2012: pathod 0.2:
* Add pathoc, a pathological HTTP client.
* Add libpathod.test, a truss for using pathod in unit tests.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

__mitmproxy__ is an SSL-capable man-in-the-middle proxy for HTTP. It provides a
console interface that allows traffic flows to be inspected and edited on the
fly.
__mitmdump__ is the command-line version of mitmproxy, with the same
functionality but without the user interface. Think tcpdump for HTTP.
Complete documentation and a set of practical tutorials is included in the
distribution package, and is also available at
[mitmproxy.org](http://mitmproxy.org).
Features
--------
- Intercept HTTP requests and responses and modify them on the fly.
- Save complete HTTP conversations for later replay and analysis.
- Replay the client-side of an HTTP conversations.
- Replay HTTP responses of a previously recorded server.
- Reverse proxy mode to forward traffic to a specified server.
- Make scripted changes to HTTP traffic using Python.
- SSL certificates for interception are generated on the fly.

mitmproxy
^^^^^^^^^
|travis| |appveyor| |coverage| |latest_release| |python_versions|
This repository contains the **mitmproxy** and **pathod** projects.
``mitmproxy`` is an interactive, SSL-capable intercepting proxy with a console
interface.
``mitmdump`` is the command-line version of mitmproxy. Think tcpdump for HTTP.
``mitmweb`` is a web-based interface for mitmproxy.
``pathoc`` and ``pathod`` are perverse HTTP client and server applications
designed to let you craft almost any conceivable HTTP request, including ones
that creatively violate the standards.
Documentation & Help
--------------------
General information, tutorials, and precompiled binaries can be found on the mitmproxy
and pathod websites.
|mitmproxy_site|
The latest documentation for mitmproxy is also available on ReadTheDocs.
|mitmproxy_docs|
Join our discussion forum on Discourse to ask questions, help
each other solve problems, and come up with new ideas for the project.
|mitmproxy_discourse|
Join our developer chat on Slack if you would like to contribute to mitmproxy itself.

Installation
------------
The installation instructions are `here <http://docs.mitmproxy.org/en/stable/install.html>`__.
If you want to contribute changes, keep on reading.
Contributing
------------
As an open source project, mitmproxy welcomes contributions of all forms. If you would like to bring the project forward,
please consider contributing in the following areas:
- **Maintenance:** We are *incredibly* thankful for individuals who are stepping up and helping with maintenance. This includes (but is not limited to) triaging issues, reviewing pull requests and picking up stale ones, helping out other users in our forums_, creating minimal, complete and verifiable examples or test cases for existing bug reports, updating documentation, or fixing minor bugs that have recently been reported.
- **Code Contributions:** We actively mark issues that we consider are `good first contributions`_. If you intend to work on a larger contribution to the project, please come talk to us first.
Development Setup
-----------------
To get started hacking on mitmproxy, please follow the `advanced installation`_ steps to install mitmproxy from source, but stop right before running ``pip3 install mitmproxy``. Instead, do the following:
.. code-block:: text
git clone https://github.com/mitmproxy/mitmproxy.git
cd mitmproxy
./dev.sh # "powershell .\dev.ps1" on Windows
The *dev* script will create a `virtualenv`_ environment in a directory called "venv"
and install all mandatory and optional dependencies into it. The primary
mitmproxy components - mitmproxy and pathod - are installed as
"editable", so any changes to the source in the repository will be reflected
live in the virtualenv.
The main executables for the project - ``mitmdump``, ``mitmproxy``,
``mitmweb``, ``pathod``, and ``pathoc`` - are all created within the
virtualenv. After activating the virtualenv, they will be on your $PATH, and
you can run them like any other command:
.. code-block:: text
. venv/bin/activate # "venv\Scripts\activate" on Windows
mitmdump --version
Testing
-------
If you've followed the procedure above, you already have all the development
requirements installed, and you can run the full test suite (including tests for code style and documentation) with tox_:
.. code-block:: text
tox
For speedier testing, we recommend you run `pytest`_ directly on individual test files or folders:
.. code-block:: text
cd test/mitmproxy/addons
pytest --cov mitmproxy.addons.anticache --looponfail test_anticache.py
As pytest does not check the code style, you probably want to run ``tox -e lint`` before committing your changes.
Please ensure that all patches are accompanied by matching changes in the test
suite. The project tries to maintain 100% test coverage and enforces this strictly for some parts of the codebase.
Documentation
-------------
The mitmproxy documentation is build using Sphinx_, which is installed
automatically if you set up a development environment as described above. After
installation, you can render the documentation like this:
.. code-block:: text
cd docs
make clean
make html
make livehtml
The last command invokes `sphinx-autobuild`_, which watches the Sphinx directory and rebuilds
the documentation when a change is detected.
Code Style
----------
Keeping to a consistent code style throughout the project makes it easier to
contribute and collaborate. Please stick to the guidelines in
`PEP8`_ and the `Google Style Guide`_ unless there's a very
good reason not to.
This is automatically enforced on every PR. If we detect a linting error, the
PR checks will fail and block merging. You can run our lint checks yourself
with the following command:
.. code-block:: text
tox -e lint

The proxy situation on Android is [an
embarrasment](http://code.google.com/p/android/issues/detail?id=1273). It's
scarcely credible, but Android didn't have a global proxy setting at all until
quite recently, and it's still not supported on many common Android versions.
In the meantime the app ecosystem has grown used to life without this basic
necessity, and many apps merrily ignore it even if it's there. The upshot is
that in many cases the only way to make interception work on Android is to do
it without relying on the proxy settings.
We used an Asus Transformer Prime TF201 with Android 4.0.3 in the examples
below - your device may differ, but the broad process should be similar.
Installing the mitmproxy certificate
====================================
The first step is to install mitmproxy's interception certificate on the
Android device. In your ~/.mitmproxy directory, there should be a file called
__mitmproxy-ca-cert.cer__ - we need to transfer this file to
__/sdcard/Downloads__ on the Android device. If this file doesn't exist for
you, your certs were generated with an older version of mitmproxy - just copy
the __mitmproxy-ca-cert.pem__ file to __mitmproxy-ca-cert.cer__ and proceed
from there.
In this case, we're using wget from Better Terminal Emulator Pro to transfer
the certificate from a local HTTP server. Other terminal applications may work,
and you might also transfer the file via external media like an SDcard:
<img src="android-shellwgetmitmproxyca.png"/>
Once we have the certificate on the local disk, we need to import it into the
list of trusted CAs. Go to Settings -&gt; Security -&gt; Credential Storage,
and select "Install from storage":
<img src="android-settingssecuritymenu.png"/>
The certificate in /sdcard/Downloads is automatically located and offered for
installation. Installing the cert will delete the download file from the local
disk:
<img src="android-settingssecurityinstallca.png"/>
Afterwards, you should see the certificate listed in the Trusted Credentials

If you're lucky enough to be working with an app that obeys the wireless proxy
settings, you're just about done - simply configure the settings to point at
mitmproxy. If not, proceed to the next step...
Working around Android's proxy shortcomings
===========================================
In response to Android's proxy situation, a number of apps have been created to
duct-tape proxy support onto the OS. These tools work by running a rudimentary
local proxy on the device, and forwarding all traffic destined for HTTP/S ports
to it using iptables. Since the proxy is running locally, it can detect what
the final IP address of the redirected traffic would have been. The local proxy
then connects to a user-configured upstream proxy, and initiates a proxy
CONNECT request to the destination IP.
Now, if the configured upstream proxy is mitmproxy, we have a slight problem.
Proxy requests from the Android device in this scheme will specify only the
destination IP address, __not__ the destination domain. Mitmproxy needs the
target domain to generate a valid interception certificate. The solution is
mitmproxy's [upstream certificate](@!urlTo("upstreamcerts.html")!@) option.
When this is active, mitmproxy makes a connection to the upstream server to
obtain the certificate Common Name and Subject Alternative Names.
Adding all this together, we can achieve reliable Android interception with
only a few more minutes of setup. The instructions below show how to set up an
Android device with
[ProxyDroid](https://play.google.com/store/apps/details?id=org.proxydroid) (the
local "duct-tape" proxy implementation) to achieve interception.
Install ProxyDroid
------------------
First, root your device - this is required to install ProxyDroid. Then install
ProxyDroid from the Google Play store:
<img src="android-proxydroidinstall.png"/>
You will be prompted for super-user access, which you must allow. Next, enter
the ProxyDroid settings, and change the proxy settings to point to your
mitmproxy instance. When you're done, it should look something like this:
<img src="android-proxydroidsettings.png"/>
In this case, our mitmproxy instance is at the host __maru.otago.ac.nz__,
running on port __8080__.
When you start mitmproxy, make sure that the upstream certificate option is set
(use the _--upstream-cert_ command-line option, or enable it interactively
using the _o_ shortcut):
<pre class="terminal">
mitmproxy --upstream-cert
</pre>

## Using Pip
The preferred way to install mitmproxy is to use
[pip](http://pypi.python.org/pypi/pip). A single command will install the
latest release of mitmproxy, along with all its dependencies:
<pre>
sudo pip install mitmproxy
</pre>
## From Source
- When installing from source, you will need to install the
[dependencies](@!urlTo("intro.html")!@) by hand.
- Then run the following command from the base of the source distribution:
<pre>
sudo python setup.py install
</pre>
## OSX
- Make sure that XCode is installed from the App Store, and that the
command-line tools have been downloaded (XCode/Preferences/Downloads).
- Install __pip__ using the following command:
<pre>
sudo easy_install pip
</pre>
- Now use __pip__ to set up the dependencies and do the install:
<pre>
sudo pip install mitmproxy
</pre>
This procedure may vary if, for instance, you've installed Python from an
external source like [homebrew](http://mxcl.github.com/homebrew/). In that
case, the easiest way to proceed is to first install __easy_install__, then
continue as above.
There are a few bits of customization you might want to do to make mitmproxy
comfortable to use. At the moment, mitmproxy's color scheme is optimized for a
dark background terminal, so you probably want to change the default. You can

__mitmdump__ is the command-line companion to mitmproxy. It provides
tcpdump-like functionality to let you view, record, and programmatically
transform HTTP traffic. See the _--help_ flag output for complete
documentation.
## Example: saving traffic
<pre class="terminal">
> mitmdump -w outfile
</pre>
Start up mitmdump in proxy mode, and write all traffic to __outfile__.
## Example: client replay
<pre class="terminal">
> mitmdump -nc outfile
</pre>
Start mitmdump without binding to the proxy port (_-n_), then replay all
requests from outfile (_-c filename_). Flags combine in the obvious way, so
you can replay requests from one file, and write the resulting flows to
another:
<pre class="terminal">
> mitmdump -nc srcfile -w dstfile
</pre>
See the [Client-side Replay](@!urlTo("clientreplay.html")!@) section for more information.
## Example: running a script
<pre class="terminal">
> mitmdump -s examples/add_header.py
</pre>
This runs the __add_header.py__ example script, which simply adds a new header
to all responses.
## Example: scripted data transformation
<pre class="terminal">
> mitmdump -ns examples/add_header.py -r srcfile -w dstfile
</pre>
This command loads flows from __srcfile__, transforms it according to the
specified script, then writes it back to __dstfile__.

__mitmproxy__ is a console tool that allows interactive examination and

## Flow list
The flow list shows an index of captured flows in chronological order.
<img src="@!urlTo("screenshots/mitmproxy.png")!@"/>
- __1__: A GET request, returning a 302 Redirect response.
- __2__: A GET request, returning 16.75kb of text/html data.
- __3__: A replayed request.
- __4__: Intercepted flows are indicated with orange text. The user may edit
these flows, and then accept them (using the _a_ key) to continue. In this
case, the request has been intercepted on the way to the server.
- __5__: A response intercepted from the server on the way to the client.
- __6__: The event log can be toggled on and off using the _e_ shortcut key. This
pane shows events and errors that may not result in a flow that shows up in the
flow pane.
- __7__: Flow count.
- __8__: Various information on mitmproxy's state. In this case, we have an
interception pattern set to ".*".
- __9__: Bind address indicator - mitmproxy is listening on port 8080 of all
interfaces.
## Flow view
The __Flow View__ lets you inspect and manipulate a single flow:
<img src="@!urlTo("screenshots/mitmproxy-flowview.png")!@"/>
- __1__: Flow summary.
- __2__: The Request/Response tabs, showing you which part of the flow you are
currently viewing. In the example above, we're viewing the Response. Hit _tab_
to switch between the Response and the Request.
- __3__: Headers.
- __4__: Body.
- __5__: View Mode indicator. In this case, we're viewing the body in __hex__
mode. The other available modes are __pretty__, which uses a number of
heuristics to show you a friendly view of various content types, and __raw__,
which shows you exactly what's there without any changes. You can change modes
using the _m_ key.
## Grid Editor
Much of the data that we'd like to interact with in mitmproxy is structured.
For instance, headers, queries and form data can all be thought of as a list of
key/value pairs. Mitmproxy has a built-in editor that lays this type of data
out in a grid for easy manipulation.
At the moment, the Grid Editor is used in four parts of mitmproxy:
- Editing request or response headers (_e_ for edit, then _h_ for headers in flow view)
- Editing a query string (_e_ for edit, then _q_ for query in flow view)
- Editing a URL-encoded form (_e_ for edit, then _f_ for form in flow view)
- Editing replacement patterns (_R_ globally)
If there is is no data, an empty editor will be started to let you add some.
Here is the editor showing the headers from a request:
<img src="@!urlTo("screenshots/mitmproxy-kveditor.png")!@"/>
To edit, navigate to the key or value you want to modify using the arrow or vi
navigation keys, and press enter. The background color will change to show that
you are in edit mode for the specified field:
<img src="@!urlTo("screenshots/mitmproxy-kveditor-editmode.png")!@"/>
Modify the field as desired, then press escape to exit edit mode when you're
done. You can also add a row (_a_ key), delete a row (_d_ key), spawn an
external editor on a field (_e_ key). Be sure to consult the context-sensitive
help (_?_ key) for more.
# Example: Interception
__mitmproxy__'s interception functionality lets you pause an HTTP request or
response, inspect and modify it, and then accept it to send it on to the server
or client.
### 1: Set an interception pattern
<img src="@!urlTo('mitmproxy-intercept-filt.png')!@"/>
We press _i_ to set an interception pattern. In this case, the __~q__ filter
pattern tells __mitmproxy__ to intercept all requests. For complete filter
syntax, see the [Filter expressions](@!urlTo("filters.html")!@) section of this
document, or the built-in help function in __mitmproxy__.
### 2: Intercepted connections are indicated with orange text:
<img src="@!urlTo('mitmproxy-intercept-mid.png')!@"/>
### 3: You can now view and modify the request:
<img src="@!urlTo('mitmproxy-intercept-options.png')!@"/>
In this case, we viewed the request by selecting it, pressed _e_ for "edit"
and _m_ for "method" to change the HTTP request method.
### 4: Accept the intercept to continue:
<img src="@!urlTo('mitmproxy-intercept-result.png')!@"/>
Finally, we press _a_ to accept the modified request, which is then sent on to
the server. In this case, we changed the request from an HTTP GET to
OPTIONS, and Google's server has responded with a 405 "Method not allowed".

In practice, it's pretty common for the replacement literal to be long and
complex. For instance, it might be an XSS exploit that weighs in at hundreds or
thousands of characters. To cope with this, there's a variation of the
replacement hook specifier that lets you load the replacement text from a file.

__mitmproxy__ has a powerful scripting API that allows you to modify flows
on-the-fly or rewrite previously saved flows locally.
The mitmproxy scripting API is event driven - a script is simply a Python
module that exposes a set of event methods. Here's a complete mitmproxy script
that adds a new header to every HTTP response before it is returned to the
client:
$!example("examples/add_header.py")!$
The first argument to each event method is an instance of ScriptContext that
lets the script interact with the global mitmproxy state. The __response__
event also gets an instance of Flow, which we can use to manipulate the
response itself.
## Events
### start(ScriptContext)
Called once on startup, before any other events.
###clientconnect(ScriptContext, ClientConnect)
Called when a client initiates a connection to the proxy. Note that
a connection can correspond to multiple HTTP requests.
###request(ScriptContext, Flow)
Called when a client request has been received. The __Flow__ object is
guaranteed to have a non-None __request__ attribute.
### response(ScriptContext, Flow)
Called when a server response has been received. The __Flow__ object is
guaranteed to have non-None __request__ and __response__ attributes.
### error(ScriptContext, Flow)
Called when a flow error has occurred, e.g. invalid server responses, or
interrupted connections. This is distinct from a valid server HTTP error
response, which is simply a response with an HTTP error code. The __Flow__
object is guaranteed to have non-None __request__ and __error__ attributes.
### clientdisconnect(ScriptContext, ClientDisconnect)
Called when a client disconnects from the proxy.
### done(ScriptContext)
Called once on script shutdown, after any other events.
## API
The main classes you will deal with in writing mitmproxy scripts are:
<table class="kvtable">
<tr>
<th>libmproxy.flow.ClientConnection</th>
<td>Describes a client connection.</td>
</tr>
<tr>
<th>libmproxy.flow.ClientDisconnection</th>
<td>Describes a client disconnection.</td>
</tr>
<tr>
<th>libmproxy.flow.Error</th>
<td>A communications error.</td>
</tr>
<tr>
<th>libmproxy.flow.Flow</th>
<td>A collection of objects representing a single HTTP transaction.</td>
</tr>
<tr>
<th>libmproxy.flow.Headers</th>
<td>HTTP headers for a request or response.</td>
</tr>
<tr>
<th>libmproxy.flow.ODict</th>
<td>A dictionary-like object for managing sets of key/value data. There
is also a variant called CaselessODict that ignores key case for some
calls (used mainly for headers).</td>
</tr>
<tr>
<th>libmproxy.flow.Response</th>
<td>An HTTP response.</td>
</tr>
<tr>
<th>libmproxy.flow.Request</th>
<td>An HTTP request.</td>
</tr>
<tr>
<th>libmproxy.flow.ScriptContext</th>
<td> A handle for interacting with mitmproxy's from within scripts. </td>
</tr>
<tr>
<th>libmproxy.certutils.SSLCert</th>
<td>Exposes information SSL certificates.</td>
</tr>

The canonical API documentation is the code. You can view the API documentation
using pydoc (which is installed with Python by default), like this:

## Running scripts on saved flows
Sometimes, we want to run a script on __Flow__ objects that are already
complete. This happens when you start a script, and then load a saved set of
flows from a file (see the "scripted data transformation" example on the
[mitmdump](@!urlTo("mitmdump.html")!@) page). It also happens when you run a
one-shot script on a single flow through the _|_ (pipe) shortcut in mitmproxy.
In this case, there are no client connections, and the events are run in the
following order: __start__, __request__, __response__, __error__, __done__. If
the flow doesn't have a __response__ or __error__ associated with it, the
matching event will be skipped.

Server-side replay lets us replay server responses from a saved HTTP
conversation.
Matching requests with responses
--------------------------------
By default, __mitmproxy__ excludes request headers when matching incoming
requests with responses from the replay file. This works in most circumstances,
and makes it possible to replay server responses in situations where request
headers would naturally vary, e.g. using a different user agent. The _--rheader
headername_ command-line option allows you to override this behaviour by
specifying individual headers that should be included in matching.
Response refreshing
-------------------
Simply replaying server responses without modification will often result in
unexpected behaviour. For example cookie timeouts that were in the future at
the time a conversation was recorded might be in the past at the time it is
replayed. By default, __mitmproxy__ refreshes server responses before sending
them to the client. The __date__, __expires__ and __last-modified__ headers are
all updated to have the same relative time offset as they had at the time of
recording. So, if they were in the past at the time of recording, they will be
in the past at the time of replay, and vice versa. Cookie expiry times are
updated in a similar way.
You can turn off response refreshing using the _--norefresh_ argument, or using
the _o_ options shortcut within __mitmproxy__.

The first time __mitmproxy__ or __mitmdump__ is started, the following set of

This CA is used for on-the-fly generation of dummy certificates for SSL
interception. Since your browser won't trust the __mitmproxy__ CA out of the
box (and rightly so), you will see an SSL cert warning every time you visit a
new SSL domain through __mitmproxy__. When you're testing a single site through
a browser, just accepting the bogus SSL cert manually is not too much trouble,
but there are a number of cases where you will want to configure your testing
system or browser to trust the __mitmproxy__ CA as a signing root authority:
- If you are testing non-browser software that checks SSL cert validity using
the system certificate store.
- You are testing an app that makes non-interactive (JSONP, script src, etc.)
requests to SSL resources. Another workaround in this case is to manually visit
the page through the browser, and add a certificate exception.
- You just don't want to deal with the hassle of continuously adding cert
exceptions.

## The setup
In this tutorial, I'm going to show you how simple it is to creatively
interfere with Apple Game Center traffic using mitmproxy. To set things up, I
registered my mitmproxy CA certificate with my iPhone - there's a [step by step
set of instructions](@!urlTo("certinstall/ios.html")!@) elsewhere in this manual. I then
started mitmproxy on my desktop, and configured the iPhone to use it as a
proxy.
## Taking a look at the Game Center traffic
Lets take a first look at the Game Center traffic. The game I'll use in this
tutorial is [Super Mega
Worm](http://itunes.apple.com/us/app/super-mega-worm/id388541990?mt=8) - a
great little retro-apocalyptic sidescroller for the iPhone:
<center>
<img src="@!urlTo("tutorials/supermega.png")!@"/>
</center>
After finishing a game (take your time), watch the traffic flowing through
mitmproxy:
<center>
<img src="@!urlTo("tutorials/one.png")!@"/>
</center>
We see a bunch of things we might expect - initialisation, the retrieval of
leaderboards and so forth. Then, right at the end, there's a POST to this
tantalising URL:
<pre>
https://service.gc.apple.com/WebObjects/GKGameStatsService.woa/wa/submitScore
</pre>
The contents of the submission are particularly interesting:
<!--(block|syntax("xml"))-->
<plist version="1.0">
<dict>
<key>category</key>
<string>SMW_Adv_USA1</string>
<key>score-value</key>
<integer>55</integer>
<key>timestamp</key>
<integer>1301553284461</integer>
</dict>
</plist>
<!--(end)-->
This is a [property list](http://en.wikipedia.org/wiki/Property_list),
containing an identifier for the game, a score (55, in this case), and a
timestamp. Looks pretty simple to mess with.
## Modifying and replaying the score submission
Lets edit the score submission. First, select it in mitmproxy, then press
__enter__ to view it. Make sure you're viewing the request, not the response -
you can use __tab__ to flick between the two. Now press __e__ for edit. You'll
be prompted for the part of the request you want to change - press __b__ for
body. Your preferred editor (taken from the EDITOR environment variable) will
now fire up. Lets bump the score up to something a bit more ambitious:
<!--(block|syntax("xml"))-->
<plist version="1.0">
<dict>
<key>category</key>
<string>SMW_Adv_USA1</string>
<key>score-value</key>
<integer>2200272667</integer>
<key>timestamp</key>
<integer>1301553284461</integer>
</dict>
</plist>
<!--(end)-->
Save the file and exit your editor.
The final step is to replay this modified request. Simply press __r__ for
replay.
## The glorious result and some intrigue
<center>
<img src="@!urlTo("tutorials/leaderboard.png")!@"/>
</center>
And that's it - according to the records, I am the greatest Super Mega Worm
player of all time.
Curiously, the top competitors' scores are all the same: 2,147,483,647. If you
think that number seems familiar, you're right: it's 2^31-1, the maximum value
you can fit into a signed 32-bit int. Now let me tell you another peculiar
thing about Super Mega Worm - at the end of every game, it submits your highest
previous score to the Game Center, not your current score. This means that it
stores your highscore somewhere, and I'm guessing that it reads that stored
score back into a signed integer. So, if you _were_ to cheat by the relatively
pedestrian means of modifying the saved score on your jailbroken phone, then
2^31-1 might well be the maximum score you could get. Then again, if the game
itself stores its score in a signed 32-bit int, you could get the same score
through perfect play, effectively beating the game. So, which is it in this
case? I'll leave that for you to decide.

- command-line: _--upstream-cert_
- mitmproxy shortcut: _o_, then _u_
Normally, mitmproxy uses the target domain specified in a client's proxy
request to generate an interception certificate. When __upstream-cert__ mode is
activated a different procedure is followed: a connection is made to the
specified remote server to retrieve its __Common Name__ and __Subject
Alternative Names__. This feature is especially useful when the client
specifies an IP address rather than a host name in the proxy request. If this
is the case, we can only generate a certificate if we can establish the __CN__
and __SANs__ from the upstream server.
Note that __upstream-cert__ mode does not work when the remote server relies on
[Server Name Indication](http://en.wikipedia.org/wiki/Server_Name_Indication).
Luckily, SNI is still not very widely used.

.. _certinstall:
About Certificates
==================
Introduction
------------
Mitmproxy can decrypt encrypted traffic on the fly, as long as the client
trusts its built-in certificate authority. Usually this means that the
mitmproxy CA certificates have to be installed on the client device.
Quick Setup
-----------
By far the easiest way to install the mitmproxy certificates is to use the
built-in certificate installation app. To do this, just start mitmproxy and
configure your target device with the correct proxy settings. Now start a
browser on the device, and visit the magic domain **mitm.it**. You should see
something like this:
.. image:: certinstall-webapp.png
Click on the relevant icon, follow the setup instructions for the platform
you're on and you are good to go.
Installing the mitmproxy CA certificate manually
------------------------------------------------
Sometimes using the quick install app is not an option - Java or the iOS
Simulator spring to mind - or you just need to do it manually for some other
reason. Below is a list of pointers to manual certificate installation
documentation for some common platforms.
The mitmproxy CA cert is located in ``~/.mitmproxy`` after it has been generated at the first
start of mitmproxy.

The mitmproxy certificate authority
-----------------------------------
The first time **mitmproxy** or **mitmdump** is run, the mitmproxy Certificate
Authority (CA) is created in the config directory (``~/.mitmproxy`` by default).
This CA is used for on-the-fly generation of dummy certificates for each of the
SSL sites that your client visits. Since your browser won't trust the
mitmproxy CA out of the box, you will see an SSL certificate warning every
time you visit a new SSL domain through mitmproxy. When you are testing a
single site through a browser, just accepting the bogus SSL cert manually is
not too much trouble, but there are a many circumstances where you will want to
configure your testing system or browser to trust the mitmproxy CA as a
signing root authority. For security reasons, the mitmproxy CA is generated uniquely on the first start and is not shared between mitmproxy installations on different devices.
Certificate Pinning
^^^^^^^^^^^^^^^^^^^
Some applications employ `Certificate Pinning`_ to prevent man-in-the-middle attacks.
This means that **mitmproxy** and **mitmdump's** certificates will not be
accepted by these applications without modifying them. It is recommended to use the
:ref:`passthrough` feature in order to prevent **mitmproxy** and **mitmdump** from intercepting
traffic to these specific domains. If you want to intercept the pinned connections, you need to patch the application manually. For Android and (jailbroken) iOS devices, various tools exist to accomplish this.
CA and cert files
-----------------
The files created by mitmproxy in the .mitmproxy directory are as follows:
===================== ==========================================================================
mitmproxy-ca.pem The certificate **and the private key** in PEM format.
mitmproxy-ca-cert.pem The certificate in PEM format.
Use this to distribute on most non-Windows platforms.
mitmproxy-ca-cert.p12 The certificate in PKCS12 format. For use on Windows.
mitmproxy-ca-cert.cer Same file as .pem, but with an extension expected by some Android devices.
===================== ==========================================================================
Using a custom certificate
--------------------------
You can use your own certificate by passing the ``--cert [domain=]path_to_certificate`` option to
mitmproxy. Mitmproxy then uses the provided certificate for interception of the
specified domain instead of generating a certificate signed by its own CA.
The certificate file is expected to be in the PEM format. You can include
intermediary certificates right below your leaf certificate, so that your PEM
file roughly looks like this:
.. code-block:: none
-----BEGIN PRIVATE KEY-----
<private key>
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
<cert>
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
<intermediary cert (optional)>
-----END CERTIFICATE-----
For example, you can generate a certificate in this format using these instructions:
>>> openssl genrsa -out cert.key 2048
>>> openssl req -new -x509 -key cert.key -out cert.crt
(Specify the mitm domain as Common Name, e.g. *.google.com)
>>> cat cert.key cert.crt > cert.pem
Now, you can run mitmproxy with the generated certificate:
**For all domain names**
``>>>mitmproxy --cert *=cert.pem``
**For specific domain names**
``>>>mitmproxy --cert *.example.com=cert.pem``
**Note:** ``*.example.com`` is for all the subdomains. You can also use ``www.example.com`` for a particular subdomain.
Using a custom certificate authority
------------------------------------
By default, mitmproxy will use ``~/.mitmproxy/mitmproxy-ca.pem`` as
the certificate authority to generate certificates for all domains for which no
custom certificate is provided (see above). You can use your own certificate
authority by passing the ``--cadir DIRECTORY`` option to mitmproxy. Mitmproxy
will then look for ``mitmproxy-ca.pem`` in the specified directory. If
no such file exists, it will be generated automatically.
Using a client side certificate
-------------------------------
You can use a client certificate by passing the ``--client-certs DIRECTORY|FILE``
option to mitmproxy. Using a directory allows certs to be selected based on
hostname, while using a filename allows a single specific certificate to be used for
all SSL connections. Certificate files must be in the PEM format and should
contain both the unencrypted private key and the certificate.
Multiple certs by Hostname
^^^^^^^^^^^^^^^^^^^^^^^^^^
If you've specified a directory to ``--client-certs``, then the following
behavior will be taken:
If you visit example.org, mitmproxy looks for a file named ``example.org.pem`` in the specified
directory and uses this as the client cert.

As discussed in [the Flow View section of the mitmproxy
overview](@!urlTo("mitmproxy.html")!@), mitmproxy allows you to inspect and
manipulate flows. When inspecting a single flow, mitmproxy uses a number of
heuristics to show a friendly view of various content types; if mitmproxy
cannot show a friendly view, mitmproxy defaults to a __raw__ view.
Each content type invokes a different flow viewer to parse the data and display
the friendly view. Users can add custom content viewers by adding a view class
to contentview.py, discussed below.
## Adding a new View class to contentview.py
The content viewers used by mitmproxy to present a friendly view of various
content types are stored in contentview.py. Reviewing this file shows a number
of classes named ViewSomeDataType, each with the properties: __name__,
__prompt__, and __content\_types__ and a function named __\_\_call\_\___.
Adding a new content viewer to parse a data type is as simple as writing a new
View class. Your new content viewer View class should have the same properties
as the other View classes: __name__, __prompt__, and __content\_types__ and a
__\_\_call\_\___ function to parse the content of the request/response.
* The __name__ property should be a string describing the contents and new content viewer;
* The __prompt__ property should be a two item tuple:
- __1__: A string that will be used to display the new content viewer's type; and
- __2__: A one character string that will be the hotkey used to select the new content viewer from the Flow View screen;
* The __content\_types__ property should be a list of strings of HTTP Content\-Types that the new content viewer can parse.
* Note that mitmproxy will use the content\_types to try and heuristically show a friendly view of content and that you can override the built-in views by populating content\_types with values for content\_types that are already parsed -- e.g. "image/png".
After defining the __name__, __prompt__, and __content\_types__ properties of
the class, you should write the __\_\_call\_\___ function, which will parse the
request/response data and provide a friendly view of the data. The
__\_\_call\_\___ function should take the following arguments: __self__,
__hdrs__, __content__, __limit__; __hdrs__ is a MultiDict object containing
the headers of the request/response; __content__ is the content of the
request/response, and __limit__ is an integer representing the amount of data
to display in the view window.
The __\_\_call\_\___ function returns two values: (1) a string describing the
parsed data; and (2) the parsed data for friendly display. The parsed data to
be displayed should be a list of strings formatted for display. You can use
the __\_view\_text__ function in contentview.py to format text for display.
Alternatively, you can display content as a series of key-value pairs; to do
so, prepare a list of lists, where each list item is a two item list -- a key
that describes the data, and then the data itself; after preparing the list of
lists, use the __common.format\_keyvals__ function on it to prepare it as text
for display.
If the new content viewer fails or throws an exception, mitmproxy will default
to a __raw__ view.

Recent versions of WireShark can use these log files to decrypt packets.
You can specify the key file path in WireShark via
:samp:`Edit -> Preferences -> Protocols -> SSL -> (Pre)-Master-Secret log filename`.
Note that :envvar:`SSLKEYLOGFILE` is respected by other programs as well, e.g. Firefox and Chrome.

Ignore Domains
==============
There are two main reasons why you may want to exempt some traffic from mitmproxy's interception
mechanism:
- **Certificate pinning:** Some traffic is is protected using `Certificate Pinning`_ and
mitmproxy's interception leads to errors. For example, the Twitter app, Windows Update or
the Apple App Store fail to work if mitmproxy is active.
- **Convenience:** You really don't care about some parts of the traffic and just want them to go
away. Note that mitmproxy's "Limit" option is often the better alternative here, as it is
not affected by the limitations listed below.
If you want to peek into (SSL-protected) non-HTTP connections, check out the :ref:`tcpproxy`
feature.
If you want to ignore traffic from mitmproxy's processing because of large response bodies,
take a look at the :ref:`responsestreaming` feature.
How it works
------------
================== ======================
command-line ``--ignore regex``
mitmproxy shortcut :kbd:`o` then :kbd:`I`
================== ======================
mitmproxy allows you to specify a regex which is matched against a ``host:port`` string
(e.g. "example.com:443") to determine hosts that should be excluded.
Limitations
-----------
There are two important quirks to consider:
- **In transparent mode, the ignore pattern is matched against the IP and ClientHello SNI host.** While we usually infer the
hostname from the Host header if the ``--host`` argument is passed to mitmproxy, we do not
have access to this information before the SSL handshake. If the client uses SNI however, then we treat the SNI host as an ignore target.
- **In regular mode, explicit HTTP requests are never ignored.** [#explicithttp]_ The ignore pattern is
applied on CONNECT requests, which initiate HTTPS or clear-text WebSocket connections.
Tutorial
--------
If you just want to ignore one specific domain, there's usually a bulletproof method to do so:
1. Run mitmproxy or mitmdump in verbose mode (``-v``) and observe the ``host:port``
information in the serverconnect messages. mitmproxy will filter on these.
2. Take the ``host:port`` string, surround it with ^ and $, escape all dots (. becomes \\.)
and use this as your ignore pattern:
.. code-block:: none
:emphasize-lines: 6,7,9
>>> mitmdump -v
127.0.0.1:50588: clientconnect
127.0.0.1:50588: request
-> CONNECT example.com:443 HTTP/1.1
127.0.0.1:50588: Set new server address: example.com:443
127.0.0.1:50588: serverconnect
-> example.com:443
^C
>>> mitmproxy --ignore ^example\.com:443$
Here are some other examples for ignore patterns:
.. code-block:: none
# Exempt traffic from the iOS App Store (the regex is lax, but usually just works):
--ignore apple.com:443
# "Correct" version without false-positives:
--ignore '^(.+\.)?apple\.com:443$'
# Ignore example.com, but not its subdomains:
--ignore '^example.com:'
# Ignore everything but example.com and mitmproxy.org:
--ignore '^(?!example\.com)(?!mitmproxy\.org)'

.. _responsestreaming:
Response Streaming
==================
By using mitmproxy's streaming feature, response contents can be passed to the client incrementally
before they have been fully received by the proxy. This is especially useful for large binary files
such as videos, where buffering the whole file slows down the client's browser.
By default, mitmproxy will read the entire response, perform any indicated
manipulations on it and then send the (possibly modified) response to
the client. In some cases this is undesirable and you may wish to "stream"
the response back to the client. When streaming is enabled, the response is
not buffered on the proxy but directly sent back to the client instead.
On the command-line
-------------------
Streaming can be enabled on the command line for all response bodies exceeding a certain size.
The SIZE argument understands k/m/g suffixes, e.g. 3m for 3 megabytes.
================== =================
command-line ``--stream SIZE``
================== =================
.. warning::
When response streaming is enabled, **streamed response contents will not be
recorded or preserved in any way.**
.. note::
When response streaming is enabled, the response body cannot be modified by the usual means.
Customizing Response Streaming
------------------------------
You can also use a script to customize exactly which responses are streamed.
Responses that should be tagged for streaming by setting their ``.stream``
attribute to ``True``:
.. literalinclude:: ../../examples/complex/stream.py
:caption: examples/complex/stream.py
:language: python
Implementation Details
----------------------
When response streaming is enabled, portions of the code which would have otherwise performed
changes on the response body will see an empty response body. Any modifications will be ignored.
Streamed responses are usually sent in chunks of 4096 bytes. If the response is sent with a
``Transfer-Encoding: chunked`` header, the response will be streamed one chunk at a time.
Modifying streamed data
-----------------------
If the ``.stream`` attribute is callable, ``.stream`` will wrap the generator that yields all
chunks.

>>> mitmdump -R https://httpbin.org -p 443
>>> curl https://localhost/
# mitmproxy will use TLS on both ends.
Host Header
-----------
In reverse proxy mode, mitmproxy automatically rewrites the Host header to match the
upstream server. This allows mitmproxy to easily connect to existing endpoints on the
open web (e.g. ``mitmproxy -R https://example.com``).
However, keep in mind that absolute URLs within the returned document or HTTP redirects will
NOT be rewritten by mitmproxy. This means that if you click on a link for "http://example.com"
in the returned web page, you will be taken directly to that URL, bypassing mitmproxy.
One possible way to address this is to modify the hosts file of your OS so that "example.com"
resolves to your proxy's IP, and then access the proxy by going directly to example.com.
Make sure that your proxy can still resolve the original IP, or specify an IP in mitmproxy.

.. _serverreplay:
Server-side replay
==================
Server-side replay lets us replay server responses from a saved HTTP
conversation.
Matching requests with responses
--------------------------------
By default, :program:`mitmproxy` excludes request headers when matching incoming
requests with responses from the replay file. This works in most circumstances,
and makes it possible to replay server responses in situations where request
headers would naturally vary, e.g. using a different user agent.
The ``--rheader headername`` command-line option allows you to override
this behaviour by specifying individual headers that should be included in matching.
Response refreshing
-------------------
Simply replaying server responses without modification will often result in
unexpected behaviour. For example cookie timeouts that were in the future at
the time a conversation was recorded might be in the past at the time it is
replayed. By default, :program:`mitmproxy` refreshes server responses before sending
them to the client. The **date**, **expires** and **last-modified** headers are
all updated to have the same relative time offset as they had at the time of
recording. So, if they were in the past at the time of recording, they will be
in the past at the time of replay, and vice versa. Cookie expiry times are
updated in a similar way.
You can turn off response refreshing using the ``--norefresh`` argument, or using
the :kbd:`o` options shortcut within :program:`mitmproxy`.
Replaying a session recorded in Reverse-proxy Mode
--------------------------------------------------
If you have captured the session in reverse proxy mode, in order to replay it you
still have to specify the server URL, otherwise you may get the error:
'HTTP protocol error in client request: Invalid HTTP request form (expected authority or absolute...)'.
During replay, when the client's requests match previously recorded requests, then the
respective recorded responses are simply replayed by mitmproxy.
Otherwise, the unmatched requests is forwarded to the upstream server.
If forwarding is not desired, you can use the --kill (-k) switch to prevent that.

information gained - the **Common Name** and **Subject Alternative Names** - is
then used to generate the interception certificate, which is sent to the client
so the connection can continue.
This rather intricate little dance lets us seamlessly generate correct
certificates even if the client has specified only an IP address rather than the
hostname. It also means that we don't need to sniff additional data to generate
certs in transparent mode.

How mitmproxy works
===================
Mitmproxy is an enormously flexible tool. Knowing exactly how the proxying
process works will help you deploy it creatively, and take into account its
fundamental assumptions and how to work around them. This document explains
mitmproxy's proxy mechanism in detail, starting with the simplest unencrypted
explicit proxying, and working up to the most complicated interaction -
transparent proxying of TLS-protected traffic [#tls]_ in the presence of `Server
Name Indication`_.
Explicit HTTP
-------------
Configuring the client to use mitmproxy as an explicit proxy is the simplest and
most reliable way to intercept traffic. The proxy protocol is codified in the
`HTTP RFC`_, so the behaviour of both the client and the server is well defined,
and usually reliable. In the simplest possible interaction with mitmproxy, a
client connects directly to the proxy, and makes a request that looks like this:
.. code-block:: none
GET http://example.com/index.html HTTP/1.1
This is a proxy GET request - an extended form of the vanilla HTTP GET request
that includes a schema and host specification, and it includes all the
information mitmproxy needs to proceed.
.. image:: schematics/how-mitmproxy-works-explicit.png
:align: center
1. The client connects to the proxy and makes a request.
2. Mitmproxy connects to the upstream server and simply forwards the request on.
Explicit HTTPS
--------------
The process for an explicitly proxied HTTPS connection is quite different. The
client connects to the proxy and makes a request that looks like this:
.. code-block:: none
CONNECT example.com:443 HTTP/1.1
A conventional proxy can neither view nor manipulate an TLS-encrypted data
stream, so a CONNECT request simply asks the proxy to open a pipe between the
client and server. The proxy here is just a facilitator - it blindly forwards
data in both directions without knowing anything about the contents. The
negotiation of the TLS connection happens over this pipe, and the subsequent
flow of requests and responses are completely opaque to the proxy.
The MITM in mitmproxy
^^^^^^^^^^^^^^^^^^^^^
This is where mitmproxy's fundamental trick comes into play. The MITM in its
name stands for Man-In-The-Middle - a reference to the process we use to
intercept and interfere with these theoretically opaque data streams. The basic
idea is to pretend to be the server to the client, and pretend to be the client
to the server, while we sit in the middle decoding traffic from both sides. The
tricky part is that the `Certificate Authority`_ system is designed to prevent
exactly this attack, by allowing a trusted third-party to cryptographically sign
a server's certificates to verify that they are legit. If this signature doesn't
match or is from a non-trusted party, a secure client will simply drop the
connection and refuse to proceed. Despite the many shortcomings of the CA system
as it exists today, this is usually fatal to attempts to MITM an TLS connection
for analysis. Our answer to this conundrum is to become a trusted Certificate
Authority ourselves. Mitmproxy includes a full CA implementation that generates
interception certificates on the fly. To get the client to trust these
certificates, we :ref:`register mitmproxy as a trusted CA with the device
manually <certinstall>`.
Complication 1: What's the remote hostname?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To proceed with this plan, we need to know the domain name to use in the
interception certificate - the client will verify that the certificate is for
the domain it's connecting to, and abort if this is not the case. At first
blush, it seems that the CONNECT request above gives us all we need - in this
example, both of these values are "example.com". But what if the client had
initiated the connection as follows:
.. code-block:: none
CONNECT 10.1.1.1:443 HTTP/1.1
Using the IP address is perfectly legitimate because it gives us enough
information to initiate the pipe, even though it doesn't reveal the remote
hostname.
Mitmproxy has a cunning mechanism that smooths this over - :ref:`upstream
certificate sniffing <upstreamcerts>`. As soon as we see the CONNECT request, we
pause the client part of the conversation, and initiate a simultaneous
connection to the server. We complete the TLS handshake with the server, and
inspect the certificates it used. Now, we use the Common Name in the upstream
certificates to generate the dummy certificate for the client. Voila, we have
the correct hostname to present to the client, even if it was never specified.
Complication 2: Subject Alternative Name
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Enter the next complication. Sometimes, the certificate Common Name is not, in
fact, the hostname that the client is connecting to. This is because of the
optional `Subject Alternative Name`_ field in the certificate that allows an
arbitrary number of alternative domains to be specified. If the expected domain
matches any of these, the client will proceed, even though the domain doesn't
match the certificate CN. The answer here is simple: when we extract the CN from
the upstream cert, we also extract the SANs, and add them to the generated dummy
certificate.
Complication 3: Server Name Indication
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
One of the big limitations of vanilla TLS is that each certificate requires its
own IP address. This means that you couldn't do virtual hosting where multiple
domains with independent certificates share the same IP address. In a world with
a rapidly shrinking IPv4 address pool this is a problem, and we have a solution
in the form of the `Server Name Indication`_ extension to the TLS protocols.
This lets the client specify the remote server name at the start of the TLS
handshake, which then lets the server select the right certificate to complete
the process.
SNI breaks our upstream certificate sniffing process, because when we connect
without using SNI, we get served a default certificate that may have nothing to
do with the certificate expected by the client. The solution is another tricky
complication to the client connection process. After the client connects, we
allow the TLS handshake to continue until just **after** the SNI value has been
passed to us. Now we can pause the conversation, and initiate an upstream
connection using the correct SNI value, which then serves us the correct
upstream certificate, from which we can extract the expected CN and SANs.
Putting it all together
^^^^^^^^^^^^^^^^^^^^^^^
Lets put all of this together into the complete explicitly proxied HTTPS flow.
.. image:: schematics/how-mitmproxy-works-explicit-https.png
:align: center
1. The client makes a connection to mitmproxy, and issues an HTTP CONNECT request.
2. Mitmproxy responds with a ``200 Connection Established``, as if it has set up the CONNECT pipe.
3. The client believes it's talking to the remote server, and initiates the TLS connection.
It uses SNI to indicate the hostname it is connecting to.
4. Mitmproxy connects to the server, and establishes an TLS connection using the SNI hostname
indicated by the client.
5. The server responds with the matching certificate, which contains the CN and SAN values
needed to generate the interception certificate.
6. Mitmproxy generates the interception cert, and continues the
client TLS handshake paused in step 3.
7. The client sends the request over the established TLS connection.
8. Mitmproxy passes the request on to the server over the TLS connection initiated in step 4.
Transparent HTTP
----------------
When a transparent proxy is used, the connection is redirected into a proxy at
the network layer, without any client configuration being required. This makes
transparent proxying ideal for those situations where you can't change client
behaviour - proxy-oblivious Android applications being a common example.
To achieve this, we need to introduce two extra components. The first is a
redirection mechanism that transparently reroutes a TCP connection destined for
a server on the Internet to a listening proxy server. This usually takes the
form of a firewall on the same host as the proxy server - `iptables`_ on Linux
or pf_ on OSX. Once the client has initiated the connection, it makes a vanilla
HTTP request, which might look something like this:
.. code-block:: none
GET /index.html HTTP/1.1
Note that this request differs from the explicit proxy variation, in that it
omits the scheme and hostname. How, then, do we know which upstream host to
forward the request to? The routing mechanism that has performed the redirection
keeps track of the original destination for us. Each routing mechanism has a
different way of exposing this data, so this introduces the second component
required for working transparent proxying: a host module that knows how to
retrieve the original destination address from the router. In mitmproxy, this
takes the form of a built-in set of modules_ that know how to talk to each
platform's redirection mechanism. Once we have this information, the process is
fairly straight-forward.
.. image:: schematics/how-mitmproxy-works-transparent.png
:align: center
1. The client makes a connection to the server.
2. The router redirects the connection to mitmproxy, which is typically
listening on a local port of the same host. Mitmproxy then consults the
routing mechanism to establish what the original destination was.
3. Now, we simply read the client's request...
4. ... and forward it upstream.
Transparent HTTPS
-----------------
The first step is to determine whether we should treat an incoming connection as
HTTPS. The mechanism for doing this is simple - we use the routing mechanism to
find out what the original destination port is. All incoming connections pass
through different layers which can determin the actual protocol to use.
Automatic TLS detection works for SSLv3, TLS 1.0, TLS 1.1, and TLS 1.2 by
looking for a *ClientHello* message at the beginning of each connection. This
works independently of the used TCP port.
From here, the process is a merger of the methods we've described for
transparently proxying HTTP, and explicitly proxying HTTPS. We use the routing
mechanism to establish the upstream server address, and then proceed as for
explicit HTTPS connections to establish the CN and SANs, and cope with SNI.
