The rotor mechanism changes the electrical connections between the keys and the lights with each keypress. Entering ciphertext transforms it back into readable plaintext. If plain text is entered, the lit-up letters are the encoded ciphertext. In typical use, one person enters text on the Enigma's keyboard and another person writes down which of 26 lights above the keyboard lights up at each key press. The Enigma machine was considered to be so secure that even the most top-secret messages were enciphered on its electrical circuits.Įnigma has an electromechanical rotor mechanism that scrambles the 26 letters of the alphabet. The Germans believed, erroneously, that use of the Enigma machine enabled them to communicate securely and thus enjoy a huge advantage in World War II. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. Copy the result, which should start with ixv., click new session, set the wheels to A C A T and paste it, a string of "J" should come out.The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. To decrypt, click on new session, set the wheels to A D O G and paste the text above.

The enigma reflector prevented a key encoding to itself. This procedure was used for communications between submarine officers. While this encryption algorithm has been broken in the past, we can apply Bruce Schneier saying " given enough rounds, pretty much anything is secure" and recommend at least double encrypting a text with different settings.

The machine can be configured and used through the touchscreen LCD, but it can also be used through the USB cable as a virtual serial port. A small chain can be used to prevent the lid from falling back. The instruction sheets were recreated in the proper scale and can be glued to the inside of the lid.Ī Houseworks 1131 hinge attaches the top of the lid to the base. Once ten (10) plugs are set, the Uhr switch is shown, this is also set by dragging in a circular motion.Ī wood or clear acrylic case was created that completely encases the machine and exposes the USB and power connectors. The plugboard is configured in a third screen by touching the bottom of the screen. The wheels can be changed and their ring positions set in a realistic way by dragging along the perimeter of the wheel. To change the settings, the logo is touched and the open machine view is shown. The main screen is shown on power up, The machine can be used to encrypt and decrypt messages. This project uses the three screen solution for configuring the enigma machine without the use of menus. Rijmenants describes in exquisite detail the operation, internals, and real messages sent using the enigma machine. To get an introduction to the enigma machine and its operation, the following links may be helpful: The initial inspiration to create this was the Franklin Heath Enigma Simulator for Android.
