This method should be called after you finish encrypting one message and are ready to start the next one. After calling it, you must call <a class="el" href="class_simple_keying_interface.html#_x_m_a_c_c___basea26">SetKey()</a> or <a class="el" href="class_simple_keying_interface.html#_x_m_a_c_ca33">Resynchronize()</a> before using this object again. This method is not implemented on decryption objects.
