The web app (and the excel sheet below) is a historically accurate simulation of the M3 Enigma code machine as used in World War 2. Rotors 1,2,3,4,5 are wired as they were in the original machine. Rotors 6,7,8,9,10 are new rotors which can be re-wired in any way you like, provided a genuine permutation of the alphabet is chosen. Thus, to create your own bespoke rotor, enter the letters A to Z (each exactly once) and choose a "notch" letter on the "Rotor Build" tab in the web app.
The "notch" is the point at which a rotor will cause the rotor to its left to rotate. The rightmost rotor rotates after each key press.
