+synopsis:            Generate and verify HMAC-based authentication tokens.
+description:         Originally designed for use within OpenStack clusters,
+                     /Fernet/ is intended to be fast and light-weight, with
+                     non-persistent tokens. Fernet tokens are signed with a
+                     SHA256 HMAC and their contents encrypted with AES128
+                     in CBC mode.
