Thanks for the report, @firnkes, I agreed that this would be an improvement on the default Nimbus behavior. 0 we support the HMAC SHA-256 algorithm, which the JWT specification identifies using the string "HS256". Thanks, I will use your solution since it looks more elegant. But I found nimbus library to be more feature rich and the only one that could work with JWKS. The public key used for verification is obtained from the JSON Web Key (JWK) Set URL supplied via the constructor. This means that you can always read headers and payload by manually Base64URL-decoding it. JWT with EdDSA / Ed25519 signature. io works like this: you paste a JWT (base64 token in the form of header. decode(accessToken); String claims = jwt.
