Class Jwks.CRV

java.lang.Object

io.jsonwebtoken.security.Jwks.CRV

Enclosing class:

Jwks

public static final class Jwks.CRV
extends Object

Constants for all standard JWK crv (Curve) parameter values defined in the JSON Web Key Elliptic Curve Registry (including its Edwards Elliptic Curve additions). Each standard algorithm is available as a (public static final) constant for direct type-safe reference in application code. For example:

 Jwks.CRV.P256.keyPair().build();

They are also available together as a Registry instance via the get() method.

Since:

0.12.0
