Re: Enigma machine strenght using a computer

Hello,

I was wondering what kind of encryption strenght we were looking at for
an enigma machine with say 512 rotors, each rotor having 256 (0 to 255)
states to rotate into.

I know it depends on how the rotors move but what bounds are we looking
at? At least what and at most what?

The machine taking any character in extended ASCII (between 0 and 255)
and stays within 0 and 255.

Give up any idea of reviving a rotor machine for a serious purpose.

The *ultimate* military rotor machine was a Russian machine called "violet" (google for lots of information). Violet had 10 rotors with complex movement and fixed all the know problems with Enigma. When it was first introduced it was for high security messages and was down-graded as time went on. It was retired in the late 80's or early 90's with the Russians believing that it gave only *1 hour* of security.

So, someone is very good at cracking them and there time is over.
