"Heil Hitler"....how can these two words help in breaking the most sophisticated machine of that time in The Imitation Game (2014)?
The actual decryption was very complex but Bletchley Park was given a BIG clue because...
To aid this process, all Turing needed was a word (or a group of words) that he was positive the Germans would use in each of their Enigma-encrypted messages. What was that word, or rather, that phrase?
Germans put the phrase ‘Heil Hitler’ at the end of every encrypted message. This seemingly small mistake eventually contributed to their ultimate defeat.
