Notes for cracking the Enigma code of the nazis, prove to be found in the restoration of a codebreakingfacility at Bletchley Park. The codekrakers used the paper as an insulating material under the roof.
The documents appear to be already in 2013, to be found in the restoration of Hut 6, which is codenamed Station X bore in Bletchley Park by the city of Milton Keynes, so message The Times. The paperwork was since that time frozen for conservation, and is now restored to about a month to be exhibited. After the war all the papers of the codekrakers destroyed, but now restored works were preserved by them in the insulation under the roof and in the walls were placed by the employees of intelligence service.
Among the papers are notes made with a pencil are made, but there is also a Banbury Sheet, the only copy that still exists. When these sheets were the letters of the cipher text is perforated, after which several sheets over each other and pushed. Then there were the holes ‘ overlapping counted.
A high result could be taken into account when a hypothesis about the settings of the rotors of an Enigma machine, which the Germans in the Second world War, used to encipher messages. The information could as the cracking of intercepted messages that day may speed up. This technique was developed by Alan Turing and is also known as Banburismus called. The name refers to Banbury, where the cards were printed.
