FernetEx
Fernet takes a user-provided message (an arbitrary sequence of bytes), a key (256 bits), and the current time, and produces a token, which contains the message in a form that can't be read or altered without the key.
This package is compatible with the other implementations at https://github.com/fernet. They can exchange tokens freely among each other.
