-/**
- * This class provides the functionality of a key agreement (or key
- * exchange) protocol.
- * The keys involved in establishing a shared secret are created by one of the
- * key generators (<code>KeyPairGenerator</code> or
- * <code>KeyGenerator</code>), a <code>KeyFactory</code>, or as a result from
- * an intermediate phase of the key agreement protocol
- * (see <a href = "#doPhase(java.security.Key, boolean)">doPhase</a>).
- * 
- * For each of the correspondents in the key exchange, <code>doPhase</code>
- * needs to be called. For example, if this key exchange is with one other
- * party, <code>doPhase</code> needs to be called once, with the
- * <code>lastPhase</code> flag set to <code>true</code>.
- * If this key exchange is
- * with two other parties, <code>doPhase</code> needs to be called twice,
- * the first time setting the <code>lastPhase</code> flag to
- * <code>false</code>, and the second time setting it to <code>true</code>.
- * There may be any number of parties involved in a key exchange.
