/**
 * KeyGenerator for the TLS PRF. Note that although the PRF is used in a number
 * of places during the handshake, this class is usually only used to calculate
 * the Finished messages. The reason is that for those other uses more specific
 * PKCS#11 mechanisms have been defined (CKM_SSL3_MASTER_KEY_DERIVE, etc.).
 *
 * <p>This class supports the CKM_TLS_PRF mechanism from PKCS#11 v2.20 and
 * the older NSS private mechanism.
