    The Construction - Early versions of the machine had three rotors (wheels) mounted freely on a single spindle, which together were called the "scrambler", and a "QWERTZUIO" keyboard which was standard in Germany but it was upper case only and had no number keys or punctuation keys.Numbers had to be written in text form. Enigma also had a "lampboard", similar to the keyboard, which indicated ...

    An Enigma machine is a famous encryption machine used by the Germans during WWII to transmit coded messages. An Enigma machine allows for billions and billions of ways to encode a message, making it incredibly difficult for other nations to crack German codes during the war — for a time the code seemed unbreakable. Alan Turing and other researchers exploited a few weaknesses in the ...
