JWT signing (JWS) and verification, with first-class ES256, JWK and JWK Set (JWKS) support.
Supports the HS256, RS256 and ES256 algorithms (for now). PR for others are welcome.
Supports exp and nbf validations. (Other validations will not be
supported, because they are mostly application specific and can be easily
implemented by applications themselves.)
See the examples folder for some examples.
Uses good old openssl for crypto. Because ring does not expose some necessary APIs, and others doesn't seem mature enough.
