The cryptanalyst now knew the plugboard, the rotor order, and the absolute setting of the rotors for the doubled key, but he did not know the ring setting. He also knew what the message key setting should be, but that setting was useless without knowing the ring setting. The ring setting could be anything, and that meant the Poles did know how to position the rotors for the message body. All the work up to this point had focussed on exploiting the doubled key. To determine the ring setting, the attention now shifted to the actual message.
