dynamic verifyJWS(String token, String publicKey) {
  try {
    final jwt = JWT.verify(

      EdDSAPublicKey(hex.decode(publicKey)),
      checkHeaderType: false,
    );

    return jwt.payload;
  } on JWTExpiredException {
    print("jwt expired");
  } on JWTException catch (ex) {
    print(ex.message);
