jwtf

https://github.com/brindu/jwtf

JWTF allows you to configure how your JSON Web Token are generated. With JWT you are free to choose from a few (a lot !) of options like the signing algorithm you crave for, the associated secret key and all the reserved claims you wish to use ! JWTF offers you a way to configure most of it for your application, so you can concentrate on the access and policy logic you want to put inside your token.
