Hackers... :cool:

Via the Numberphile-Channel I wanted to dig deeper into the mechanics of the enigma machine.

I tried the -- Universal Enigma -- Simulation, compared it to an android version and even got a C# Version from Codeproject

BUT


I really don't get the simplest encryption to work in my brain. I tried all day.

WHY / HOW does "A" converted to "B" - I don't even understand the rotor in the middle going to "c" instead of "j"

If the Setup is Reflector B and Walzen I,II,III...
I hope I understand that with "--W" the "a" is wired to a "b" and then the rotor moves.

In the second "-W-" the "b" should become a "j" .. but NO... it becomes a "c"... WHY?

I debugged the C# Program from Codeproject and even there the
forward direction is a-a-b-c-d-f
and not a-a-j-...

Any help is appreciated.
