Mathematicians and intelligence experts, with the help of primitive early computers, began the complex and urgent task of cracking the Enigma code.

In 1939, with German invasion looming, the Poles shared their information with the British, who in turn established the Government Code and Cipher School at Bletchley Park in Buckinghamshire. Close links between the German and Polish engineering industries allowed the Polish Cipher Bureau to reconstruct an Enigma machine and read the Wehrmacht's messages between 19. The first people who came close to cracking the Enigma code were the Polish. German code experts added new plugs, circuits and features to the machine during the pre-war years, but its basic principle remained the same. To decode the message, the recipient needed to know the exact settings of the wheels. The Enigma machine enabled its operator to type a message, then 'scramble' it using a letter substitution system, generated by variable rotors and an electric circuit. The Enigma story began in the 1920s, when the German military - using an 'Enigma' machine developed for the business market – began to communicate in unintelligible coded messages.

However, the meticulous work of code breakers based at Britain's Bletchley Park cracked the secrets of German wartime communication, and played a crucial role in the final defeat of Germany. It does not store any personal data.It was thanks to ULTRA that we won the war.ĭuring World War II, Germany believed that its secret codes for radio messages were indecipherable to the Allies.

The parts form a varying electrical circuit, so that pressing the keys completed a circuit with current flowing through the components and lighting one of the display lamps to indicate a letter. It was a combination of mechanical and electrical subsystems including a keyboard, rotating disks called rotors arranged adjacently along a spindle, and stepping components to turn the rotors when keys were pressed. The Enigma machine had been around since the early 1920s and is most closely associated with Nazi Germany. The principal cipher was “Heimisch” for U-boats and surface ships in home waters, including the Atlantic. Naval Enigma signals used different ciphers, each with its own daily key (rotor order, ring settings, plugboard connections, and ground setting). Breaking the naval code gave the British an advantage in the Battle of the Atlantic. The machine used by the German army was decrypted as early as 1932 by Polish cryptographers, who later passed their methodology along to the British and French.
