Project description
cryptography is a package which provides cryptographic recipes andprimitives to Python developers. Our goal is for it to be your “cryptographicstandard library”. It supports Python 3.6+ and PyPy3 7.2+.
cryptography includes both high level recipes and low level interfaces tocommon cryptographic algorithms such as symmetric ciphers, message digests, andkey derivation functions. For example, to encrypt something withcryptography’s high level symmetric encryption recipe:
>>> 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.")>>> tokenb'...'>>> f.decrypt(token)b'A really secret message. Not for prying eyes.'You can find more information in the documentation.
You can install cryptography with:
$ pip install cryptographyFor full details see the installation documentation.
Discussion
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 #pyca on irc.libera.chat to ask questions or getinvolved.
