``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.'
