This is an extremely simplified version of the Enigma machine. The machine has only 1 rotor with stepping. It works by using a substitution cipher. The green button toggles encrypt and decrypt mode. Rotor position can be set using the slider and stepping adjusted with the other slider.
TYPE SLOW AND LIGHT. STOP AND START TO RESET. Can you decode the message? (Machine settings are in The Invisible Message.) refn_ofowx_zpo_mbioyn
