    • JoseHttpSigner

      public JoseHttpSigner(JWK key)
      A constructor with a key for signing.

      An algorithm needs to be specified by the alg parameter in the JWK.

      Parameters:
      key - A signing key. This must be a private key.
      Throws:
      IllegalArgumentException - The key is null, is not a private key, or does not contain the alg parameter.

    • JoseHttpSigner

      public JoseHttpSigner(JWK key, JWSAlgorithm alg)
      A constructor with a key and algorithm for signing.

      An algorithm needs to be specified by either the alg argument passed to this method or the alg parameter in the JWK. When both means are used, the specified algorithms must be identical.

      Parameters:
      key - A signing key. This must be a private key.
      alg - An algorithm for signing.
      Throws:
      IllegalArgumentException - The key is null, is not a private key, or the alg parameter of the key does not match the algorithm specified by the alg argument. Or, the key does not contain the alg parameter and the alg argument is null.
