[A++] The Enigma PRO Encryption Machine (updated!)

Here is the concept behind this representation of the Enigma Machine: The program uses virtual "wheels" that contain all of the printable characters on the keyboard. Think of the first wheel as the keyboard you are typing on. All of the wheels contain the same characters, but in a random, non-repeating order. Each time a character is pressed, the location of that character on the one wheel is used to as the index to lift the character off of the next wheel. Then the new character is searched for in the next wheel, and the pattern repeats itself across each wheel. The character lifted off of the final wheel is the output. This step is repeated for each character in the message. Decryption simply sends the message backwards through a similar, but reversed process. What really makes this encryption effective is that like the real life machine, the wheels rotate either to the left or right after each character. So the relationship between each character shifts constantly. As a result, even repeating characters such as "aaaaaaaaaaa" are represented with garbage such as "zkhfXSURMBe". Another great part about an encryption scheme like this is it's flexibility. You can add more wheels, more characters per wheel, change the order of the wheels, the directions the wheels spin, and change the starting position of each wheel. So, unless someone can figure out: 1) How many wheels are being used... 2) How many characters are on each wheel... 3) The order of the wheels... 4) The direction they spin... 5) The initial position of each wheel... 6) The order of the characters on each wheel... It would be virtually impossible to look at the encrypted characters and determine their relationship to one another. There are so many possibilities and combinations of the above criteria, it would have to be solved through brute force. I am no mathematician, so if anyone can tell me the possible combinations, I would appreciate it. When the Germans used this machine, it baffled the Allies, who frantically tried to break it with no success. It wasn't until a German U-Boat was forced to surface in a naval battle and was captured that the Allies got a huge break. An Enigma machine was captured along with a code book that showed the information needed to decrypt the messages. The U-Boat was scuttled and the crew was kept in a top secret location. The U-Boat was simply considered lost during battle and Germans continued the war not knowing the truth. When the war in the Atlantic turned for the worse, the Germans, who believed their code to be unbreakable, believed that there were spies in their top level officials. They never considered that the code was being decrypted through a captured machine, so as a result, they set up elaborate networks to try and find these "spies". Paranoia being what it was, many loyal German officers were tortured and murdered for treason, even though they had committed no such offense. This code is by no means complete. I will try and enhance it's speed and toughen it's encryption even further. I'll also try and build a better sample app with more features. If you find a problem or have a suggestion, I would love to hear it.
