Hi, The special algorithm was necessary because the root keys could be used in session_register() as global variables, which have certain naming restrictions. This is no longer necessary since session_register() has been deprecated. I wrote a patch a while ago to use php_var_serialize but the complication emerged of adding a version number to the serialized string (otherwise migrating existing sessions is awkward). I haven't had time to work on it but can dig up the latest code if you'd like, it will be another few weeks until I can pick it up again. Regards, Arpad
