The deciphering of Enigma remains as one of the most significant cryptanalyst achievements of all time. One of the main reasons the Allies were successful in cracking the code was due to their ability to look beyond the microcosm of the daily messages they received and focus on tackling the code at the highest level. Alan Turing's idea to create a machine that could handle Enigma was the exact creativity needed to win the war. Since the origins of cryptography, the battle between cryptanalysts and cryptographers was typically of human brainpower, and whoever had better linguistic or cryptographic knowledge would be the winner. However, in the Second World War, the use of a machine to encipher messages practically renders all human brainpower useless, as no human can match the speed and efficiency at which a machine can work. For this reason, it was of the utmost importance for Turing to design a machine to defeat Enigma, as the progress made by humans was simply not enough.


What is most interesting about Turing's process was that it did not use a machine to generate a key first and then possible plaintext. Instead, he looked for links between ciphertext and plaintext called cribs, and used those to generate the possible key. This way is considerably more accurate because it both decreases the risk of creating a different plaintext than intended and can be used repeatedly. Finally, allowing a machine to perform this method increased the speed at which keys could be generated and eliminated possible human error. I have no doubt that the cryptanalysts at Bletchley Park could have made errors due to the amount of stress and pressure they faced. Therefore, the Allied success can really be attributed to Turing's exceptional engineering of code-cracking machines.
