### Question:
Hash { public static Bytes blake2bf(final Bytes input) { return Bytes.wrap(digestUsingAlgorithm(input, BLAKE2BF_ALG)); } private  Hash(); static Bytes32 sha256(final Bytes input); static Bytes32 keccak256(final Bytes input); static Bytes ripemd160(final Bytes input); static Bytes blake2bf(final Bytes input); static final String KECCAK256_ALG; }### Answer:
@Test public void blake2bfCompression() { final Bytes result = Hash.blake2bf(Bytes.wrap(Hex.decode(inputBlake2bf))); assertThat(result).isEqualTo(Bytes.fromHexString(outputBlake2bf)); }
