Thread: Engima machine?

I think today encryption technology has moved on leaps & bounds. Enigma's main weakness was that it could be broken once the code breakers established a pattern. Sometimes it was hard to break in to, other times they could get in quite easily. The Naval (Shark) Code was the hardest to break, especially after a 4th rotor was added to the machine to increase the number of possible permutations. However with the help of a brilliant Post Office Engineer called Tommy Flowers, The Colossus Machine was designed and built to help break the enigma code more quickly. Colossus was the world's first programmable computer and although it only had the computing capacity of a pocket calculator it was a revolution in number crunching.

Interesting to hear Spitfire that the capacity was that of a pocket calculator when here you can see the actual machine is as its name says, Colossus compared to the calculator.
