This C++ project is an Enigma machine simulator. It implements specifically the Enigma I, but additional machines can be easily created with the defined Plugboard, Rotor, Reflector, Entrywheel, and Enigma classes.
- Modify the machine's settings in
test/run_enigmaI.cpp(no fancy CLI at the moment) - Run
./pre_build.sh - To encode/decode a message, use something like
./build/test/run_enigmaI "MESSAGE in lower or upper case"
- Plugboard
- Entry wheel (aka ETW)
- Rotors
- Reflector (aka UKW)
- Rotors with multiple notch positions
- Other Enigma variants
- CLI includes Enigma settings
