Description

The list of methods to do Hash Calculate are organized into topic(s).

Method

StringgetHashOf(String s)
get Hash Of 
MessageDigest md = MessageDigest.getInstance("SHA-256");
s += "TTM";
md.update(s.getBytes());
return byteArrayToHexString(md.digest());
StringgetHashString()
get Hash String 
long hashLong;
synchronized (hashGenerator) {
    hashLong = hashGenerator.nextLong() & 0x7FFFFFFFFFFFFFFFL;
return Long.toHexString(hashLong);
StringgetHashString(byte[] data)
get Hash String 
return stringFormat(getHash(data));
StringgetHashString(String password, String salt)
get Hash String 
return bin2hex(getHash(iterations, createPasswordKey(password, salt), hex2bin(salt)));
StringgetHashWithSalt(String input, String algorithm, String salt)
This method hashes a string according to the desired message digest algorithm. 
MessageDigest digest = MessageDigest.getInstance(algorithm);
digest.reset();
digest.update(salt.getBytes("UTF-8"));
byte[] bytes = digest.digest(input.getBytes("UTF-8"));
for (int i = 0; i < ITER; i++) {
    digest.reset();
    bytes = digest.digest(bytes);
return new BigInteger(1, bytes).toString(16);
inthash()
Optimized implementation of #hash(int[]) with 0 args. 
return 1;
inthash(Boolean value)
hash 
return value ? 1231 : 1237;
inthash(boolean value, int seed)
Alters the given seed with the hash code value computed from the given value. 
return seed * PRIME_NUMBER + (value ? 1231 : 1237);
inthash(boolean[] array)
hash 
if (array.length == 4) {
    if (!array[0] && !array[1] && !array[2] && !array[3]) {
        return 0;
    return ((array[0] ? 1 : 0) << 3) + ((array[1] ? 1 : 0) << 2) + ((array[2] ? 1 : 0) << 1)
            + (array[3] ? 1 : 0);
int n = 0;
...
inthash(byte x)
hash 
return x;
