CIPHER MACHINES AND CRYPTOLOGY
Enigma Simulator v7.0
Home Menu History Procedures Technical details Enigma Simulator


This software is an exact simulation of the 3-rotor Wehrmacht (Heer and Luftwaffe) Enigma, the 3-rotor Kriegsmarine 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. The simulator also has a picture gallery of Enigma machines. With this software you will finally be able to work with the most intriguing machine in military cryptology and examine how it works and how it was operated. A true reference to Enigma, and an educational must!

Check out the Enigma Sim Manual PDF Format to discover all the nuts and bolts of the software. All questions or feedback are welcome by e-mail or by visiting the Guestbook.
