Level one is just a single XOR pass. Its somewhat useful for comparison purposes.
CipherText is targeting niche applications that require default HTTP transmission. Its output domain can be restricted, making it possible for use encrypting query string values in CGI applicatons. I have demonstrated a site wrapper that encrypts query values, embedding them into HTML links. When returned, the values must correspond to lookup data. Also thread authentication is made possible by changing the user key at each request.
Its amazing how much you can learn about syntax, implementing the same algorithm in several languages.
