This Enigma tool is an accurate simulation of the M3 Enigma cipher machine used by the German Navy during the Second World War. This particular Enigma model utilized 3 rotors (selected from a total of 8), and had a choice of 2 reflectors. Each of the rotors has a selectable ring position, as well as a start position, and a plug board is also supported. Note: Other Enigmas of the time used more rotors and had extra reflectors available but those are not supported in this tool. Click here for an example.
