![]() ![]() ![]() Components of Enigma Machine RotorsĮach Enigma machine was supplied with a standard set of rotors (between 3 & 5) which could be inserted into the machine in various combinations. ![]() This meant that repeatedly pressing the same key would not generate the same output character. The Enigma machine encrypted the data by a combination of mechanics & electrical circuits so that each key stroke would complete an electrical pathway between the key and a light indicating the encrypted character and then would move the rotors on a notch. The breaking of the Enigma code by the code-breakers at Bletchley Park in the UK has been credited with the shortening of the duration of the war. They were initially created to protect commercial secrets but their encryption was strengthen by the German military to encrypt sensitive communications throughout the 2nd World War. The Enigma machines were a family of cipher machines which used a combination of mechanics and electrical circuitry to encode & decode messages. The code samples on this page form part of my efforts to recreate the operation of these elegant machines in Java by simulating the functional components as instances of classes. Helping her with this homework piqued my interest and so I started to do my own investigation into the mechanics of these machines.Īfter studying various web sites, I figured that I could enhance my understanding by writing a program to attempt to simulate the encoding and decoding process. She was given a piece of Maths homework in which she had to describe the purpose & operation of the Enigma Machine and encrypt/decrypt a few example pieces of text using a simplified code table. ![]()
