<PRE>Here are some ideas for PyCrypto patches:
- Documentation updates
- Bugfixes
- Python 3.x support, with some sane way of maintaining Python 2.x support
for the forseeable future. I would like to see somebody champion this,
with discussion on how this could realistically work, rather than just
one-off code dumps.
- Build autoconfiguration improvements
- 64-bit Windows support
- Camellia. Maybe. I don't want lots of new algorithms, but having more
than one cipher with a 128-bit block size is probably a good idea,
assuming the code is clean and doesn't carry any substantial copyright
restrictions.
Here are some tips for getting your patches accepted, taken from
<A HREF="http://www.pycrypto.org/:">http://www.pycrypto.org/:</A>
- Don't needlessly break compatibility with older versions of PyCrypto.
Patches that break compatibility with older version of PyCrypto,
especially PyCrypto 2.0.1, will need an explanation about why it's worth
breaking compatibility. Exception: Removing buggy code that nobody uses
is fine.
- Don't needlessly break compatibility with older versions of Python. Run
the test suite using Python 2.1 and the latest version of Python 2.x.
- Don't needlessly add complexity. The more complex the code is, the harder
it is to maintain, and the more likely it is to have bugs.
- Don't needlessly add features. Seriously. X.509 doesn't belong in
PyCrypto. Or anywhere, really.
- Don't create copyright headaches. It took me the better part of a year to
sort out the licensing ambiguities in PyCrypto 2.0.1. If you're adding
new files, include the standard PyCrypto public domain dedication at the
top.
- Whatever you do in _fastmath.c, also do in _slowmath.py. PyCrypto has two
math libraries: one that depends on libgmp, and one that doesn't. They
need to be kept synchronized with each other.
- Make small, incremental, well-documented changes. Your commit messages
should be clear and detailed. Include any applicable background
information. Your patches should do one thing. Your code should have
sensible comments.
I still don't have a lot of time to actually write code, but I'm going to
try to be more responsive to posts on the mailing list, especially if those
posts can be read and responded to on my phone. :-)
Cheers,
- Dwayne
