Examples of com.nimbusds.jose.JWSObject.sign()

com.nimbusds.jose.JWSObject.sign()
Signs this JWS object with the specified signer. The JWS object must be in a {@link State#UNSIGNED unsigned} state. @param signer The JWS signer. Must not be {@code null}. @throws IllegalStateException If the JWS object is not in an {@link State#UNSIGNED unsigned state}. @throws JOSEException If the JWS object couldn't be signed.

    // Create signer from JWK representation
    RSAKey rsaJWK = new RSAKey.Builder(rsaPublicKey).privateKey(rsaPrivateKey).build();


    JWSObject jwsObject2 = new JWSObject(new JWSHeader(JWSAlgorithm.RS256), new Payload("test123"));
    signer = new RSASSASigner(rsaJWK.toRSAPrivateKey());
    jwsObject2.sign(signer);
    Base64URL sig2 = jwsObject2.getSignature();


    assertTrue("Signature comparison", sig1.equals(sig2));
