+ * @short KNTLM class implements the NTLM authentication protocol.
+ *
+ * The KNTLM class is useful for creating the authentication structures which
+ * can be used for various servers which implements NTLM type authentication.
+ * A comprehensive description of the NTLM authentication protocol can be found
+ * at http://davenport.sourceforge.net/ntlm.html
+ * The class also contains methods to create the LanManager and NT (MD4) hashes
+ * of a password.
+ * This class doesn't maintain any state information, so all methods are static.
