This is an XTEA implementation that has both LSL and PHP scripts to allow strong encryption not only inside LSL but also between LSL and a PHP serverscript. Just a couple of hints: a) At least in the current version of CryptoJS, the encrypt() method now returns an object, so to get the actual encoded string, you need to call toString() method. This example provides an application-defined function that requests encryption based on a given privacy level and destination queue. Symmetric key encryption, also called secret key encryption, requires that the key used for encryption also be used for decryption.
