- defrost 3y agoIndeed - the Enigma decoding machines at Bletchley were the evolution of earlier designs, two iterations at least that came from the Poles. I mentioned Tutte as Bletchley can take full credit for the inhouse reverse engineering and attacks on Tunny, the Lorenz cipher, a more difficult cipher than Enigma and one used for more sensitive traffic by the Germans. Tunny had an entirely seperate dedicated class of machines used for its attacks. https://en.wikipedia.org/wiki/Lorenz_cipher https://en.wikipedia.org/wiki/Lorenz_cipher https://en.wikipedia.org/wiki/Colossus_computer https://en.wikipedia.org/wiki/Colossus_computer Colossus is thus regarded as the world's first programmable, electronic, digital computer, although it was programmed by switches and plugs and not by a stored program.
