I found a way to actually encrypt stuff. This method is fool-proof. Unless you have the key, you cannot correctly generate the message, and unless you have the message, you cannot get the key! The key isn't stored anywhere either, so someone cannot, say, get rid of the password check for the file.

Woah... This is kind of scary!

Nice! I just did something similar but a lot more basic (just ROT13/n). This is cool!

I made another encryption method called RICE (Random Integer Combination Encryption) myself. Pretty nooby, but it works!
