[openssl-users] [ANN] M2Crypto 0.27.0

M2Crypto is the most complete Python wrapper for OpenSSL
featuring RSA, DSA, DH, EC, HMACs, message digests, symmetric
ciphers; SSL functionality to implement clients and servers;
HTTPS extensions to Python’s httplib, urllib, and xmlrpclib;
unforgeable HMAC’ing AuthCookies for web session management;
FTP/TLS client and server; S/MIME. M2Crypto can also be used to
provide SSL for Twisted. Smartcards supported through the Engine

This is another less earth-shattering release (after 0.26.2 which
brought us OpenSSL 1.1.0 compatbility), one more step towards
Python 3 compatibility nirvana, still more cleanups and
accumulated bug fixes, which could be resolved before the big
python3 branch is merged.

The release is available on
https://pypi.python.org/pypi/M2Crypto/ and all communication with
the maintainer (that’s me) should go to

Talking about the python3 branch, ALL TESTS PASS on all Pythons
from 2.6, 2.7, 3.3 to 3.6!!!

Now is the time to test, help with review, and complain about
whatever is wrong! I will still keep API stable, but changes are
relatively large, so this is your opportunity to suggest whatever
substantial thing you don't like with M2Crypto. I may not make it
happen in 0.28 (which I expect to be Py3k-compatible release),
but for settling the dust down and cleanup I prepare already
0.29, which should include yet more acummulated merge requests
and bugfixes, this time ones which should be better served with
python 3 layer already happening.

Happy hacking!
