----------------------------------------------

Create a JWT (Json Web Token), sign it and return it ``base64-encoded``.

Do not forget: A JWT is "forgery-proof" because the signature hash can only be generated with
can only be generated with the correct key/salt - but all data in the JWT can be read by anyone
can be viewed through ``base64_decode()``. A JWT is by no means suitable for storing sensitive data such as
passwords or logins!
