Method

inthashCode(byte[] data)
hash Code 
if (data == null) {
    return 0;
int i = data.length;
int hc = i + 1;
while (--i >= 0) {
    hc *= 257;
    hc ^= data[i];
...
byte[]hash(String algorithm, byte[] data)
returns a hash SHA-1 of the given byte array 
try {
    MessageDigest digest = MessageDigest.getInstance(algorithm);
    return digest.digest(data);
} catch (NoSuchAlgorithmException e) {
    return null;
intgetByteArrayHash(byte[] value)
Calculate the hash code of the given byte array. 
int len = value.length;
int h = len;
if (len < 50) {
    for (int i = 0; i < len; i++) {
        h = 31 * h + value[i];
} else {
    int step = len / 16;
