The Enigma is a ciphering device used primarily during World War II by Nazi Germany. The Enigma Simulator found on this site serves to simulate that device as best as possible on a computer. To learn more about the history or theory behind the real Enigma machine, Wikipedia has an excellent article at http://wikipedia.org/wiki/Enigma_machine.
