Given the way you designed this app, I believe it is not keygenable.

Basically, what you're asking is this: "knowing the encrypted data and the original data, find the used encryption key".
It's called known-plaintext attack and it's practically impossible on modern algorithms like AES (when they are used in the way you did).

 

However, I'll be happy to be proven wrong.. ;) 

Oooooh ok, I understand and I apologize! I thought there still might be a way to somehow reverse the rijndael algorithm... (or if it's impossible, just bruteforcing until one key is found) Welp then here is one key: 8C08-UT01-70J9-9ST3-D416-09A0, writing a keygen shouldnt be too hard now :)
