Enigma cryptography machine, illustration
Enigma cryptography machine, illustration. This device was an electromechanical German encryption machine used in World War II (1939-1945). Messages were typed into the keyboard and a series of letters would light up on the display, providing the encrypted version (the ciphertext). A system of rotors meant that each letter could be enciphered as any other, except itself. At right are exploded views of the encryption cylinders. Enigma was the German's main coding device, and was mainly used to direct their submarines to attack enemy shipping convoys. The code was eventually deciphered by the Allies, by researchers working at Bletchley Park, UK.
