- Enigma, device used by the German military to encode strategic messages before and during World War II. The Enigma code was first broken by the Poles in the early 1930s. In 1939 the Poles turned their information over to the British, who set up the code-breaking group Ultra, under mathematician Alan M. Turing.

The Enigma Machine uses a system of rotating wheels (rotors) and electrical wiring to encrypt messages by polyalphabetic substitution. The basic Enigma machine includes 1 wiring board, 3 rotors and 1 reflector, each element configurable independently (machine settings changing daily).

Enigma decoder: Decrypt and translate enigma online. The Enigma cipher machine is well known for the vital role it played during WWII. Alan Turing and his attempts to crack the Enigma machine code changed history. Nevertheless, many messages could not be decrypted until today. ADFGVX.

In July 1942, Turing developed a complex code-breaking technique he named ‘Turingery’. This method fed into work by others at Bletchley in understanding the ‘Lorenz’ cipher machine. Lorenz enciphered German strategic messages of high importance: the ability of Bletchley to read these contributed greatly to the Allied war effort. Turing travelled to...
In 1936, Turing had invented a hypothetical computing device that came to be known as the ‘universal Turing machine’. After the Second World War ended, he continued his research in this area, building on his earlier work and incorporating all he'd learnt during the war. Whilst working for the National Physical Laboratory (NPL), Turing published a d...
In 1952, Alan Turing was arrested for homosexuality – which was then illegal in Britain. He was found guilty of ‘gross indecency’ (this conviction was overturned in 2013) but avoided a prison sentence by accepting chemical castration. In 1954, he was found dead from cyanide poisoning. An inquest ruled that it was suicide. The legacy of Alan Turing’...
It was not until mid-1942 that up-to-date Tunny traffic was read, using a method invented by Turing and known simply as 'Turingery'. Tunny was used in preference to Enigma for the encryption of high-level signals, for example messages from Hitler and members of the German High Command.
The military use of the Enigma and the problem facing those trying to break it. This page also allows you to go to Tony Sale's on-line Enigma simulator and to try it out on a message used in the film Enigma.
The German encryption machine, was called the Enigma. It had one hundred and three billion trillion possible settings for encoding messages. For much of the war it was thought to be unbreakable.
