Enigma is the brand name of a series of cipher machines developed in Germany between 1923 and 1945.

A number of these machines were used during World War 2 by the German Army, Navy and Air Force, this website has simulations for both the three rotor Enigma I used by the Heer (Army) and Luftwaffe (Air Force) and the four rotor Enigma M4 used by the Kriegsmarine (German Navy).

The Enigma code was cracked and read initially by the Poles in 1932 with Bletchley Park continuing and expanding on this work where they regularly read the German encrypted messages throughout the war.

Virtual Enigma is a 3d Enigma simulation which can run using just your browser. No install is necessary. It was released on Alan Turing's 109th Birthday 23rd June 2021
