Cryptanalysis of the Enigma by the letters on the top row of the Enigma keyboard. So, "continuation of message sent at 2330" was represented as "FORTYWEEPYYWEEPY". "Cribs" were fundamental to the British approach to solving Enigma keys, but guessing the plaintext for a message was a highly skilled business. So in 1940 Stuart Milner-Barry set up a special "Crib Room" in Hut 8. Foremost amongst the knowledge needed for identifying cribs was the text of previous decrypts. Bletchley Park maintained detailed indexes of message preambles, of every person, of every ship, of every unit, of every weapon, of every technical term and of repeated
Technology during World War II also developing an atomic Bomb, however, it floundered due to lack of resources despite gaining interest from the government. The collaboration between the British and the Americans led to the 1958 US-UK Mutual Defence Agreement between the two nations, whereby American nuclear weapons technology was adapted for British use. Electronics rose to prominence quickly in World War II. The British developed and progressed electronic computers which were primarily used for breaking the “Enigma” codes, which were Nazi secret codes. These codes for radio messages were indecipherable to the Allies. However, the meticulous work of code breakers based at Britain’s Bletchley
