cryptography is a package designed to expose cryptographic recipes and
primitives to Python developers. Our goal is for it to be your "cryptographic
standard library". It supports Python 2.6-2.7, Python 3.2+, and PyPy.
cryptography includes both high level recipes, and low level algorithms.
For example, to encrypt something with cryptography:
>>> from cryptography.fernet import Fernet
>>> # Put this somewhere safe!
>>> key = Fernet.generate_key()
>>> f = Fernet(key)
>>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
>>> token
'...'
>>> f.decrypt(token)
'A really secret message. Not for prying eyes.'You can find more information in the documentation.
If you run into bugs, you can file them in our issue tracker.
We maintain a cryptography-dev mailing list for development discussion.
You can also join #cryptography-dev on Freenode to ask questions or get
involved.
