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.
