JWT signing (JWS) and verification, with first class JWK and JWK Set (JWKS) support.

Supports almost all JWS algorithms:

  • HS256, HS384, HS512
  • Ed25519
  • ES256, ES384, ES512, ES256K
  • RS256, RS384, RS512
  • PS256, PS384, PS512

Supports exp and nbf validations. (Other validations will not be supported, because they are mostly application specific and can be easily implemented by applications.)

Supports converting public/private keys to/from PEM/JWK. Supports working with generic keys (where the algorithm is determined at runtime), i.e. SomePrivateKey/SomePublicKey.

Uses good old openssl for crypto.

See the examples folder for some examples.
