cryptography is a package designed to expose cryptographic recipes and
primitives to Python developers.
It is currently in early development and isn't recommended for general usage yet. It targets Python 2.6-2.7, Python 3.2+, and PyPy.
You can find more information in the documentation.
We maintain a cryptography-dev mailing list for development discussion.
You can also join #cryptography-dev on Freenode to ask questions or get
involved.
