I use TriCrypt to encrypt simple strings. It supports two directional. http://www.fiacre.net/phpcode.php (Code available at http://www.fiacre.net/download/TriCrypt.txt) Sample: Original String=World Encrypted String=Nx9yJu I haven't gotten around at figuring out how do I make the code produce only lower case letters in encrypted strings. Could someone on this list offer any suggestions on how to modify the code to support numbers and only lower case numbers. Thank you very much. -- Anas Mughal
