In the early 1920s, the Enigma machine was a portable encryption machine with rotor scramblers used for encoding and decoding confidential messages. It was progressively developed over the decades to use additional rotors and technical complexity that boosted the incremental difficulty of cracking its codes. And so began an elegant, noble cat-and-mouse game between coders and decoders that has stood the test of time. Or so we've been led to believe...
