M2Crypto = Python + OpenSSL + SWIG
M2Crypto is a crypto and SSL toolkit for Python.
M2 stands for "me, too!"
M2Crypto comes with the following:
* RSA, DSA, DH, HMACs, message digests, symmetric ciphers including AES,
* TLS functionality to implement clients and servers.
* Example SSL client and server programs, which are variously threading,
forking or based on non-blocking socket IO.
* HTTPS extensions to Python's httplib, urllib and xmlrpclib.
* Unforgeable HMAC'ing AuthCookies for web session management.
* FTP/TLS client and server.
* S/MIME v2.
* ZServerSSL: A HTTPS server for Zope.
* ZSmime: An S/MIME messenger for Zope.
We care a lot about stable API and all Python methods should be preserved,
note however that m2. namespace is considered internal to the library and
it doesn't have to be preserved. If however some change to it breaks your
app, let us know and we will try to make things working for you.
* And much more.
M2Crypto is released under a very liberal MIT licence. See LICENCE for
details.
To install, see the file INSTALL.
Look at the tests and demos for example use. Recommended reading before
deploying in production is "Network Security with OpenSSL" by John Viega,
Matt Messier and Pravir Chandra, ISBN 059600270X.
Note these caveats:
* Possible memory leaks, because some objects need to be freed on the
Python side and other objects on the C side, and these may change
between OpenSSL versions. (Multiple free's lead to crashes very
quickly, so these should be relatively rare.)
* No memory locking/clearing for keys, passphrases, etc. because AFAIK
Python does not provide the features needed. On the C (OpenSSL) side
things are cleared when the Python objects are deleted.
Have fun! Your feedback is welcome.
