Simple Encryption in Second Life

I’ve been working with methods to encrypt data being passed around my objects for the visitor reports with a symmetric cipher. The closest method available that Linden Lab provides is an XOR function. It is hard for me to consider XOR as an encryption algorithm, as it is more of simply an encoding cipher. Even though it was used in World War II, it is perhaps one of the easiest algorithms to break using frequency analysis. I’ve created some free scripts that show how to use XOR, and perhaps implimented it closer to a Vernam Cipher with a one-time pad using md5 of the password with a random nonce as the salt.
