The enigma machine and how it

Play media Enciphering and deciphering using an Enigma machine A German Enigma operator would be given a plaintext message to encrypt. For each letter typed in, a lamp indicated a different letter according to a pseudo-random substitution, based upon the wiring of the machine. The letter indicated by the lamp would be recorded as the enciphered substitution. The action of pressing a key also moved the rotor so that the next key press used a different electrical pathway, and thus a different substitution would occur.

Enigma Machine Emulator Note: This Enigma machine emulator is faithful to the workings of both the Navy M3 and M4 Enigma machines used by the German navy during World War 2and you can decipher original German messages.

The only difference between a real Enigma machine and this emulator is the way the machine is arranged and how you set it up. In the emulator all the wheel settings are visible instead of opening up the Enigmathe plugboard is above the lampboard and there is no keyboard - you use your computer's keyboard to enter letters into a single input field.

Also, there is continuous feedback of the clear text and cipher text, to save you having to note down each letter from the lampboard.

This means that the lampboard is effectively redundant, but I have included for authenticity and fun! I suggest that you first familiarise yourself with how an Enigma machine worksor at least how the emulator worksbefore you plunge in and start making secret messages. If you would like to know more, then there is plenty of further reading material available.
