Example 11 with Signature

use of io.nem.symbol.core.crypto.Signature in project nem2-sdk-java by nemtech.

the class Ed25519DsaSignerTest method signThrowsIfGeneratedSignatureIsNotCanonical.

@Test
public void signThrowsIfGeneratedSignatureIsNotCanonical() {
    // Arrange:
    final CryptoEngine engine = this.getCryptoEngine();
    final KeyPair keyPair = KeyPair.random(engine);
    final Ed25519DsaSigner dsaSigner = new Ed25519DsaSigner(keyPair) {

        @Override
        public boolean isCanonicalSignature(Signature signature) {
            return false;
        }
    };
    final byte[] input = RandomUtils.generateRandomBytes();
    // Act:
    Assertions.assertEquals("Generated signature is not canonical", Assertions.assertThrows(CryptoException.class, () -> dsaSigner.sign(input)).getMessage());
