CONTRIBUTING

HOW TO CONTRIBUTE PATCHES TO OpenSSL
------------------------------------

(Please visit https://www.openssl.org/community/getting-started.html for
other ideas about how to contribute.)

Development is coordinated on the openssl-dev mailing list (see the
above link or https://mta.openssl.org for information on subscribing).
If you are unsure as to whether a feature will be useful for the general
OpenSSL community you might want to discuss it on the openssl-dev mailing
list first.  Someone may be already working on the same thing or there
may be a good reason as to why that feature isn't implemented.

To submit a patch, make a pull request on GitHub.  If you think the patch
could use feedback from the community, please start a thread on openssl-dev
to discuss it.

Having addressed the following items before the PR will help make the
acceptance and review process faster:

    1. Anything other than trivial contributions will require a contributor
    licensing agreement, giving us permission to use your code. See
    https://www.openssl.org/policies/cla.html for details.

    2.  All source files should start with the following text (with
    appropriate comment characters at the start of each line and the
    year(s) updated):

        Copyright 20xx-20yy The OpenSSL Project Authors. All Rights Reserved.

        Licensed under the OpenSSL license (the "License").  You may not use
        this file except in compliance with the License.  You can obtain a copy
        in the file LICENSE in the source distribution or at
        https://www.openssl.org/source/license.html

    3.  Patches should be as current as possible; expect to have to rebase
    often. We do not accept merge commits; You will be asked to remove
    them before a patch is considered acceptable.

    4.  Patches should follow our coding style (see
    https://www.openssl.org/policies/codingstyle.html) and compile without
    warnings. Where gcc or clang is available you should use the
    --strict-warnings Configure option.  OpenSSL compiles on many varied
    platforms: try to ensure you only use portable features.
    Clean builds via Travis and AppVeyor are expected, and done whenever
    a PR is created or updated.

    5.  When at all possible, patches should include tests. These can
    either be added to an existing test, or completely new.  Please see
    test/README for information on the test framework.

    6.  New features or changed functionality must include
    documentation. Please look at the "pod" files in doc/apps, doc/crypto
    and doc/ssl for examples of our style.
