Updated 2019 with an added simulation of the US Navy Cryptanalytic Bombe WinEnigma is a Windows based Turing Bombe software. Turing-Welchman Bombe Simulator To gain a better understanding of how the Bombe worked, we decided to recreate an online simulator that you can use to workout Enigma settings from valid cribs. Enter something in the 'Input' area - this will be written on the tape initially as input to the machine. Interactive Turing machine simulator. Click 'Reset' to initialise the machine. It was used to help breaking the German Enigma codes and was (partly) based on the so-called BOMBA, an earlier machine developed by Polish mathematicians in 1938. It engaged in so many conflicts, that it has been accredited as a contributing factor to the outcome of numerous events during WWII.

Click on the picture below to access our online Turing-Welchman Bombe simulator and try to find the Enigma settings to decrypt the following cipher text: This is a Turing machine simulator. The TBreaker software decodes original Enigma messages with an hillclimbing algorithm. Use a simple language to create, compile and run your Turing machines save and share your own Turing machines. See below for syntax. The Enigma machine is considered as one of the best known cryptographic machines ever to be constructed, mainly because of the vital role it played during World War II. The Bombe machine, envisioned by Turing, enhanced by fellow code breaker Gordon Welchman and built by the British Tabulating Machine Company, followed up on the work of Polish mathematicians Marian Rejewski, Henryk Zygalski and Jerzy Rozycki. The Turing Bombe and US Navy Bombe simulator First created for the Alan Turing Year 2012: A Centenary Celebration of the Life and Work of Alan Turing. To use it: Load one of the example programs, or write your own in the Turing machine program area. BOMBE was the name of an electro-mechanical machine, developed during WWII by Alan Turing and Gordon Welchman, whilst working as codebreakers at Bletchley Park.
