Btw yes the program was just a joke.
Just don't.
We all get it, you wanted to be cool. Just say sorry guys, I'm a dumbstuff, I pretended to be able to create a program that all the intel agencies of the world dream of in 15 minutes. Bullstuff, that wasn't a joke. It was you inflating your e-peen. Stop digging yourself deeper into this hole and I'll happily throw you down a rope.
I do have the knowledge to make it its just it would take up a stuffload of my valuable time and not be able to crack EVERY code.
In fact, it would barely break ANY codes. Not to mention:
A program can work through all possible solutions and show them to the user (who determines gibberish vs words) but it can't magically decode something.
In other word, even the damn interface was flawed. The output would have to be a text file or a multiline textbox in order for the program to display the different possibilities. Yes, your program could technically sort out the gibberish, but often a code will make words even if it isn't decoded correctly.
Id like to see you "whip up" an interface cucumber.
You stuffhead.

You didn't even bother changing the title from "Form 1".
tl;dr; give up. You're arguing with a relatively experienced programmer, I know my stuff. Just admit you were a dumbass to try and pretend you made some miracle program and feel free to play the game.
on topic, hint: The code uses only 1 type of operation
