Ruby Fun

I've been looking into Ruby lately. For the halibut, I decided to create a rotor-based encryption program in the spirit of Enigma. Easy peas, once I quit thinking I knew how things worked and started modeling the actual machine.

Here's a snippet that shows rotor #3.

class Rotor3 < BaseRotor
 def initialize()
  super
  @rot =
  [
  [22,2,0,14,25,21,24,3,17,4,19,8,11,18,10,5,9,12,6,15,16,20,23,13,1,7],
  [2,24,1,7,9,15,18,25,11,16,14,12,17,23,3,19,20,8,13,10,21,5,0,22,6,4]
  ]
  @notches = [3,5,16,19,22]
 end
end

The @rot array-of-arrays shows how a pin on one side of the rotor is wired to a pin on the other side. The @notches array is analogous to a "notch" in the rotor where a pawl would be able to engage a ratchet, spinning the rotor adjacent to this rotor. In this example, when rotor three rotates from position 3 to position 4, the next rotor should also be rotated.
