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