``cryptography`` is a package which provides 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 interfaces to
common cryptographic algorithms such as symmetric ciphers, message digests and
key derivation functions. For example, to encrypt something with
``cryptography``'s high level symmetric encryption recipe:
.. code-block:: pycon
>>> 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.
