The Imitation Game war (and the puzzle was not set by Turing, who was no good at them). Google, which sponsored the New York Premiere of the film, launched a competition called "The Code-Cracking Challenge" on 23 November 2014. It is a skill contest where entrants must crack a code provided by Google. The prize/s will be awarded to entrant/s who crack the code and submit their entry the fastest. In November 2014, ahead of the film's US release, "The New York Times" reprinted the 1942 puzzle from "The Daily Telegraph" used in recruiting codebreakers at Bletchley Park during the Second World War.
Rotor machine programs to run afoul of U.S. export regulations which classified cryptographic implementations as munitions. Rotor machine In cryptography, a rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting secret messages. Rotor machines were the cryptographic state-of-the-art for a prominent period of history; they were in widespread use in the 1920s–1970s. The most famous example is the German Enigma machine, whose messages were deciphered by the Allies during World War II, producing intelligence code-named "Ultra". The primary component is a set of "rotors", also termed "wheels" or "drums", which are rotating disks with an array of electrical
