public final class GF256 extends Object
This class contains utility methods for performing mathematical operations over the Galois Field GF(256). Operations use a given primitive polynomial in calculations.
Throughout this package, elements of GF(256) are represented as an
int
for convenience and speed (but at the cost of memory). Only the bottom 8 bits are really used.- Since:
