In the 1920s the German Reichswehr adopts the cipher machine Enigma to secure military radio communication. During the Third Reich, Enigma machines are put into operation in numerous Wehrmacht units. Poland, which is imminently threatened by the German rearmament, begins efforts to break the Enigma-encoded messages. Marian Rejewski, a young mathematician employed by the Polish Armys General Staff, finally succeeds in reconstructing the machine, breaking its codes and decrypting its ciphers. This CD recapitulates this remarkable episode, when a brilliant 27-year-old mathematician triumphs over the advanced German war machine. A 3D-model allows for insights into the innermost parts of Enigma; an additional CD-layer offers Rejewskis Enigma calculations. Moreover, a fully functional reconstruction of the Enigma allows users to explore interactively the encoding system
