The idea revolves around encryption and decryption of an input string through this command line utility, based on a combination of a randomly generated GUID, and the GUID set within the application's core to come out with a unique byte array based on some algorithm i'm trying to design currently. We then take this byte array, and combine it with the bytes of the input string to generate our encrypted value and save the random GUID to a file for future reference to be used when we later want to decrypt the encryption back to it's original string format. The catch: You'll be able to freely 'destroy' (or rather recreate/regenerate) this internal GUID, so that the encryption is not it's former constant self so to speak. Thus enabling you to never again be able to decrypt anything that was created when that application's internal GUID was it's old self. Preview so far: More of a concept at this point in time until I figure out what kind of algorythm I want to solve for, when encrypting the string input, and reversing that process for decryption.
