 103 <p>This class contains utility methods for performing mathematical operations over
 104  the Galois Field GF(256). Operations use a given primitive polynomial in calculations.</p>
 105
 106  <p>Throughout this package, elements of GF(256) are represented as an <code>int</code>
 107  for convenience and speed (but at the cost of memory).
 108  Only the bottom 8 bits are really used.</p>
