- ``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 3.3+, and PyPy 2.6+.
- ``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.'
