Working: multiple rotor wheels (5, choose 3) (8 for naval) different wireing in each wheel plug board link 2 letters (2 way link). 10 links, 20 letters used up Fixed, non rotating wheel for relaying back through rotors Letters could not be mapped to themselves! (Biggest flaw!) Options: Random generated rotors (use random seed) rotors from given seed rotors from actual setup (if available) plug board from random seed or given seed option to skip plug board relay from random seed or given seed, or actual setup option to output text character by character (no enter required!) option to convert string (output letter individually) option to read / write string to file. option to read all setup from file. Process: Keyboard : Plug Board : Rotor 1 : Rotor 2 : Rotor 3 : Relay : Rotor 3 : Rotor 2 : Rotor 1 : Plug Board : Key lights Code Steps: Calculate rotor codes (store to dictionary) (create all 5) select 3 random rotors generate plug board values (store to dictionary) Get input char pass through plug board rotor 1 2 3 pass through relay rotor 3 2 1 pass through plug board
