I would prefer not to refer to random to avoid any confusion with the recent added random function. As uuid is not crypto safe and is not aimed to. Users will then hopefully not think about using instead of the random api. Also uuid alone may be a problem (bc?) It sounds like a logical choice. Alternatively uuid_create (). Cheers Pierre
