Examples with Sha256 com.icodici.crypto.digest.Sha256 used on opensource projects

Example 1 with Sha256

use of com.icodici.crypto.digest.Sha256 in project universa by UniversaBlockchain.

the class SymmetricKeyTest method testHashes.

@Test
public void testHashes() throws Exception {
    byte[] valid = Hex.decode("ba7816bf 8f01cfea 414140de 5dae2223 b00361a3 96177a9c b410ff61" + " f20015ad");
    Digest d = new Sha256();
    d.update('a');
    d.update("bc".getBytes());
    assertArrayEquals(valid, d.digest());
    // And SHA512 too
    valid = Hex.decode("ddaf35a193617aba cc417349ae204131 12e6fa4e89a97ea2 0a9eeee64b55d39a " + "2192992a274fc1a8 36ba3c23a3feebbd 454d4423643ce80e " + "2a9ac94fa54ca49f");
    assertArrayEquals(valid, new Sha512().digest("abc"));
}

Example 2 with Sha256

use of com.icodici.crypto.digest.Sha256 in project universa by UniversaBlockchain.

the class PublicKey method fingerprint.

@Override
public byte[] fingerprint() {
    synchronized (publicKey) {
        if (_fingerprint == null) {
            _fingerprint = new byte[33];
            _fingerprint[0] = (byte) FINGERPRINT_SHA256;
            System.arraycopy(updateDigestWithKeyComponents(new Sha256()).digest(), 0, _fingerprint, 1, 32);
        }
        return _fingerprint;
    }
}
