This code is used for file security. when you wish to write something to a file and not have it read, you use this function and the text gets altered to a format that is unreadable. All you do is supply it a string you want to encrypt and a password and the Function will return a uniquely encrypted string based solely on the password provided. The benefit of this is you do not need to keep the password in a file anywhere to compare. If you use the wrong password a useless, unreadable string is returned.
