@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"));
}
