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

Due to differences in how py.test determines which module to ``import`` the test suite actually runs against the cryptography which is in the *current* directory instead of the cryptography which is installed. The problem essentially boils down to when there is a tests/__init__.py then py.test adds the current directory to the front of the sys.path, causing it to take precedence over the installed location. This means that running the tests relies on the implicit compile that CFFI does instead of testing against what people will actually be runnning, which is the module compiled by setup.py. |

``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.'
