A JSON Web Token (JWT) is a compact token format intended for space
constrained environments such as HTTP Authorization headers and URI query
parameters, and used as a means of representing claims to be transferred
between two parties. The claims in a JWT are encoded as a JSON object that is
digitally signed.
.
The JWT specification supports several algorithms for cryptographic signing.
This library currently supports HMAC (HS256, HS384, HS512) and RSA
(RS256, RS256, RS512). Unsigned plaintext JWT's are supported too.
