Internal Program Version: cryptography  40.0.2

cryptography is a package designed to expose cryptographic
recipes and primitives to Python developers.  Our goal is
for it to be your "cryptographic standard library". It
supports Python 2.7, Python 3.4+, and PyPy-5.3+.

cryptography includes both high level recipes, and low
level interfaces to common cryptographic algorithms such as
symmetric ciphers, message digests and key derivation
functions.
