​Miscellaneous Enigma Simulator Information

This software is an exact simulation of the 3-rotor Wehrmacht (Army and Air Force) Enigma, the 3-rotor Kriegsmarine (Navy) M3, also called Funkschlussel M, and the famous 4-rotor Kriegmarine M4 Enigma cipher machine, used during World War II from 1939 until 1945. The sim has a very authentic feeling with its hands-on approach: you can select between the three models, actually lift out and insert different rotors, adjust their ring setting and set up the plugboard. The internal wiring of all rotors is identical to those that were used by the Wehrmacht and Kriegsmarine. This simulator is therefore fully compatible with the various real Enigma models and you can decrypt authentic wartime messages or encrypt and decrypt your own messages.

The program comes with a very complete 22 page helpfile, containing the manual, some original messages, the history of Enigma and all technical details of the machine.

Runs on Windows™ 98/ME/2000/XP/Vista/Win7 and on MAC and Linux with Parallels Desktop or WINE (open source).
