M3 adds a thin rotor next to the reflector and uses rotor turnover and reflector settings.
Use B or C for M3, or the B/C for M4. Reflectors determine how signals are redirected.
Rotors
Set the rotors from the reflector side (left) to the keyboard entry side (right).
Enter up to 10 letter pairs (A-Z). Leave blank for no plugboard.
Letters outside A-Z are left unchanged. Encryption and decryption use the same settings.

How It Works
Configure your Enigma machine settings (rotor positions, reflector, plugboard). Type a message and watch it encrypt character-by-character. Recipient with same settings can decrypt the message.
