public class SWIFFTX

extends java.lang.Object

This is a C++ - Java portation of the reference SWIFFTX hash function, designed by Yuriy Arbitman, Gil Dogon, Vadim Lyubashevsky, Daniele Micciancio, Chris Peikert, Alon Rosen. The NIST submission package can be found here: It also contains speed optimized versions and papers. SWIFFTX is a SHA3 candidate. The original comments are only slightly changed.

Method Detail

hash

static int[] hash(int hashbitlen,
                  byte[] data,
                  int databitlen)

Hash() provides a method to perform all-at-once processing of the input data using SWIFFTX and returns the resulting hash value. The Hash() function is called with the data to be processed, the length of the data to be processed (databitlen) and a length of the desired hash value (hashbitlen). This function utilizes the previous three function calls, namely Init(), Update(), and Final(). Parameters: - hashbitlen: the length in bits of the desired hash value - data: the input data to be hashed - databitlen: the length, in bits, of the data to be hashed Returns: - hashvalue.
