Secret WWII Enigma Codebreaking Docs Revealed
The report, written in four parts by four authors writing with no knowledge of each other's work and which reveals highly-advanced code-breaking skills, has been made public after 66 years of top secret "ultra" classification.
Simon Greenish, CEO of Bletchley Park National Code Centre said: "This extraordinary document was kept under wraps for 66 years, because the code breaking techniques used by the team at Bletchley Park to crack the Nazi enigma codes were so advanced that it was relevant for codebreakers until very recently. Bletchley Park was decades ahead of its time."
