Wasn't the whole point of Collossus that it was brute-forcing the messages on the more complex Naval keys until it found a candidate match? That's certainly what I remember from visiting Bletchley Park.
In any case, there are now (finally!) software implementations that are significantly faster than the reproduced hardware Collossus, so even if I'm not fully right brute-forcing messages should be viable.
- mckoss 16y agoFrom my understanding, Collossus was not used against Enigma, but rather, Tuny (an teletype based 5 bit XOR stream cipher).
- eftpotrm 16y agoTunny was the British codename for data from the Lorenz machine, which is what Collossus was working on. The original Enigma machines were attacked by Bombe machines developed by Polish codebreakers pre-war.
