JSON Web Token vs JSON Prettify

JSON Web Token is the fastest way to build, decode and verify JWTs on iPhone, iPad and Mac. Paste any token and instantly see its header and payload, neatly typed and editable. Sign your own tokens with the algorithm of your choice, verify signatures against your own keys, and copy the result with one tap.
