"There can be no doubt that Turing's work was a vital factor in the success."

Turing studied the materials and realized that manual methods of deciphering were useless. He proposed to create a machine that could automatically sort through the keys - this is how the "Bomb" was born. The device weighing 2.5 tons consisted of a hundred electromagnetic drums and many additional blocks. By the end of the war, 210 machines were already working at Bletchley Park, which were deciphering up to 3,000 messages per day. This significantly strengthened the position of Great Britain and influenced the outcome of the war.

"My own conclusion is that it shortened the war by at least two years."

Historian Harry Hinsley, a Bletchley Park employee during the war

The "Bomb" simulated the work of the "Enigma" and nepal telegram data selected keys using hints - already revealed messages. To do this, it checked the settings and position of the rotors, as well as the connections on the switchboard. There were many possible combinations. The machine made logical assumptions based on the content and structure of the open text, found contradictions and excluded some settings. So gradually only a few parameters remained for detailed analysis and complete decryption.

A team of scientists worked on the Bombe, including Gordon Welchman, Stuart Milner-Berry, and Hugh Alexander. However, it was Turing who was involved in the theoretical part of the work and was confident that the task of breaking Enigma was solvable.

In 2014, the story was adapted into a film called The Imitation Game.
