@Test
public void testEcKeySign() {
String password = "pass1234";
String challenge = "challenge1234";
byte[] secretTarget = Utils.doubleDigest(password.getBytes());
ECKey key = new ECKey(new BigInteger(1, secretTarget), null, true);
ECDSASignature sign = key.sign(Sha256Hash.createDouble(challenge
.getBytes()));
assertNotNull(sign);
System.out.println("sign.r=" + sign.r);
System.out.println("sign.s=" + sign.s);
String signHex = BaseEncoding.base16().encode(sign.encodeToDER());
System.out.println(signHex);
byte[] sign2byte = BaseEncoding.base16().decode(signHex);
ECDSASignature signTarget = ECDSASignature.decodeFromDER(sign2byte);
assertFalse(ECKey.verify(
Sha256Hash.createDouble("FakeChallenge".getBytes()).getBytes(),
signTarget, key.getPubKey()));
assertTrue(ECKey.verify(Sha256Hash.createDouble(challenge.getBytes())
.getBytes(), signTarget, key.getPubKey()));
