Their project is instead modeled on the original Enigma M4 cipher machine, and aside from a bit of artistic license, we think they nailed the visual style. As for functionality, the guide claims ...

In each of these configurations, the machine had a period of 16,900 (26 x 25 x 26) keyings before the mechanism returned to its original position. But there were weak points. The Enigma is simply ...

With certain settings, the machine had a very low cipher period (338 compared to 16,900 for Enigma). This wasn’t just theoretical, either. A study showed that bad settings showed up seven times ...

Turing provides an excellent example of this phenomenon in a chapter on British concerns about their Typex cipher machine. Typex was, like the German Enigma machine, based on rotors, but it was ...
