Enigma Machine Emulator

An Enigma machine emulator written in C#.

Enigma model

The project models the Enigma I, from ~1930.

Features

All the features the real Enigma I had. Plugboard, rotors with arbitrary order, and three available reflectors. Produces the same output as the real machine.

Todo

• Improve the settings query in Program.cs
  • Make it fail safe
  • Make the code prettier

Future work

• Make the machine compatible with the later Enigma models, M3 and M4.
  • Expand the machine with more rotors (M3 and M4 had up to eight).
  • Expand the machine with more reflectors (Beta and Gamma)
• Translate the code into JavaScript and make a web version of the machine.
