Method Detail

load

public static void load()

sha3

public static byte[] sha3(byte[] input)

sha3

public static String sha3(String hexInput)

Keccak-256 hash function.

Parameters:

hexInput - hex encoded input data with optional 0x prefix

Returns:

hash value as hex encoded string

sha3

public static byte[] sha3(byte[] input1,
                          byte[] input2)

sha3

public static byte[] sha3(byte[] input,
                          int start,
                          int length)

hashing chunk of the data

Parameters:

input - - data for hash

start - - start of hashing chunk

length - - length of hashing chunk

Returns:

- keccak hash of the chunk

sha512

public static byte[] sha512(byte[] input)

sha3omit12

public static byte[] sha3omit12(byte[] input,
                                byte prefixByte)

Calculates RIGTMOST160(SHA3(input)). This is used in address calculations. *

Parameters:

input - - data

Returns:

- add_pre_fix + 20 right bytes of the hash keccak of the data
