Security
|
||
========
|
||
|
||
We take the security of ``cryptography`` seriously. The following are a set of
|
||
policies we have adopted to ensure that security issues are addressed in a
|
||
timely fashion.
|
||
|
||
Reporting a security issue
|
||
--------------------------
|
||
|
||
We ask that you do not report security issues to our normal GitHub issue
|
||
tracker.
|
||
|
||
If you believe you've identified a security issue with ``cryptography``, please
|
||
report it to ``alex.gaynor@gmail.com``. Message may be optionally be encrypted
|
||
with PGP using key fingerprint
|
||
``E27D 4AA0 1651 72CB C5D2 AF2B 125F 5C67 DFE9 4084``
|
||
(this public key is available from most commonly-used key servers).
|
||
|
||
Once you've submitted an issue via email, you should receive an acknowledgment
|
||
within 48 hours, and depending on the action to be taken, you may receive
|
||
further follow-up emails.
|
||
|
||
Supported Versions
|
||
------------------
|
||
|
||
At any given time, we will provide security support for the `master`_ branch
|
||
as well as the 2 most recent releases.
|
||
|
||
New releases for OpenSSL updates
|
||
--------------------------------
|
||
|
||
As of version 0.5, ``cryptography`` statically links OpenSSL on Windows to ease
|
||
installation. Due to this, ``cryptography`` will release a new version whenever
|
||
OpenSSL has a security or bug fix release to avoid shipping insecure software.
|
||
|
||
Like all our other releases, this will be announced on the mailing list and we
|
||
strongly recommend that you upgrade as soon as possible.
|
||
|
||
Disclosure Process
|
||
------------------
|
||
|
||
Our process for taking a security issue from private discussion to public
|
||
disclosure involves multiple steps.
|
||
|
||
Approximately one week before full public disclosure, we will send advance
|
||
notification of the issue to a list of people and organizations, primarily
|
||
composed of operating-system vendors and other distributors of
|
||
``cryptography``. This notification will consist of an email message
|
||
containing:
|
||
|
||
* A full description of the issue and the affected versions of
|
||
``cryptography``.
|
||
* The steps we will be taking to remedy the issue.
|
||
* The patches, if any, that will be applied to ``cryptography``.
|
||
* The date on which the ``cryptography`` team will apply these patches, issue
|
||
new releases, and publicly disclose the issue.
|
||
|
||
Simultaneously, the reporter of the issue will receive notification of the date
|
||
on which we plan to take the issue public.
|
||
|
||
On the day of disclosure, we will take the following steps:
|
||
|
||
* Apply the relevant patches to the ``cryptography`` repository. The commit
|
||
messages for these patches will indicate that they are for security issues,
|
||
but will not describe the issue in any detail; instead, they will warn of
|
||
upcoming disclosure.
|
||
* Issue the relevant releases.
|
||
* Post a notice to the cryptography mailing list that describes the issue in
|
||
detail, point to the new release and crediting the reporter of the issue.
|
||
|
||
If a reported issue is believed to be particularly time-sensitive – due to a
|
||
known exploit in the wild, for example – the time between advance notification
|
||
and public disclosure may be shortened considerably.
|
||
|
||
The list of people and organizations who receives advanced notification of
|
||
security issues is not and will not be made public. This list generally
|
||
consists of high profile downstream distributors and is entirely at the
|
||
discretion of the ``cryptography`` team.
