The 'Enigma' machine was an electro-mechanical rotor device used to create ciphers for the encryption of secret messages. It was invented by Arthur Scherbius at the end of Word War One.
The Enigma machine is a combination of mechanical and electrical systems. The mechanical mechanism consists of a keyboard; a set of rotating disks called rotors arranged adjacently along a spindle; and a stepping mechanism to turn one or more of the rotors with each key press.
The machine was widely used by the German military during World War Two to transmit coded messages. The team which was assembled at Bletchley Park, was also known as Station X, in August 1939 were given the task of breaking the codes created by the German military. They eventually fulfilled this task and Winston Churchill made the claim that their work shortened the war by at least two years.
