Installing phpseclib is probably the easiest thing to do, you can download a copy at http://phpseclib.sourceforge.net/. Extract the zip file into a directory named \"phpseclib\" inside the \"aes\" module directory and you should be good to go. Check the README.txt for more information."), "warning");
