Part 6/9:
Turing’s unique methodology focused on the concept of “cribs”—predictable phrases likely included in the encrypted messages, such as weather reports, which often started with the word "Wetter" (German for "weather"). By aligning these expected phrases with intercepted messages, Turing and his team could narrow down the configurations of the Enigma for decoding.
However, mere logic was not enough. The process required immense computational power to handle the numerous possibilities derived from the cribs. This led Turing to develop the Bombe machine, an electro-mechanical device designed to automate the process of testing rotor settings.
