The naming of the Enigma-breaking machine "Christopher" after Turing's childhood friend, with Turing the only cryptographer working on it while others either did not help or outright opposed it. In reality, this electromechanical machine was named "Victory" and it was a collaborative, not individual, effort.

The German Enigma used a combination key to control the operation of the machine: rotor order, which rotors to install, which ring setting for each rotor, which initial setting for each rotor, and the settings of the stecker plugboard. The rotor settings were trigrams (for example, "NJR") to indicate the way the operator was to set the machine.
The stories covered various aspects of the breaking of the Enigma naval codes, the captures from the U-boat U-110 and other relevant material from German weather ship Lauenburg and München and the German armed trawler Krebs during the Lofoten raid.
The machine was developed by British mathematician Alan Turing, and it was used to decode messages sent by the Nazi military. Bought for $115, a WWII Enigma machine sells for $51,000 Skip to main ...
