There are pure software solutions available. There was a 3 kb class included with Horde for instance, which could be used very nicely. It was called HCEMD5 and could do encryption/decryption with a secret and a public key (which were simple strings). You can also look in pear.php.net and see if any packages are good for you. I think this may do what you want: http://pear.php.net/package/Crypt_RC4 You can use PEAR packages without needing a priviledged user to install them on the server. -- Romanian Web Developers - http://ROWD.ORG
