This is incredibly, incredibly exciting for me. A friend and I actually just finished writing a program that simulates the process of cracking a Geheimschreiber[0] (one of the successors to the Enigma machine), which was cracked at Bletchley Park. There are several ways to break the encryption today, especially given the available computing power. However, we happened to discover a technique that requires no probabilistic guessing or brute forcing (this is unusual for crypto cracking - usually at least a bit[1] of guessing is required). The technique works as long as a sufficient number of ciphertexts are observed, and this threshold is a very small number. For me, it'll be exciting to see if there is any more information on the technique that they used. (From digging around so far, I've been able to find a small bit of information about the device itself from a modern perspective, but none about what they actually did at the time).
