-/**
- * This class implements a "message authentication code" (MAC), a method
- * to ensure the integrity of data transmitted between two parties who
- * share a common secret key.
- *
- * <p>The best way to describe a MAC is as a <i>keyed one-way hash
- * function</i>, which looks like:
- *
- * <blockquote><p><code>D = MAC(K, M)</code></blockquote>
- *
- * <p>where <code>K</code> is the key, <code>M</code> is the message,
- * and <code>D</code> is the resulting digest. One party will usually
- * send the concatenation <code>M || D</code> to the other party, who
- * will then verify <code>D</code> by computing <code>D'</code> in a
- * similar fashion. If <code>D == D'</code>, then the message is assumed
- * to be authentic.
