What is the Enigma Machine?
The Enigma machine is essentially a complicated substitution cipher machine. It consists of a plug board, a light board, a set of rotors and a reflector. The machine came with a number of rotors, each of which rotor contained a random substitution alphabet. The user would select between 3 and 5 rotors to use at any one time, depending on the size of the machine. The plug board was another variable for the machine. Certain letters would be connected reciprocally to each other.
