cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.

Turns out you can't trust it to safely compute the max salt length allowed for PSS, so now we get to do it ourselves. We also check for whether the key size is large enough for the selected hash function (PSS only for now, PKCS1 coming in another PR) |

``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.'
