I need a way to link every user name to a unique ID held in a table in the database. I've tried several ways of doing this but all of which are not secure enough. It's essential that no one be able to view the user names, though the unique identifyers will be viewable to all users on the public schema. My best bet right now is to store the user names in an encrypted table with a column for the user name and a column for the id. This method seems to be the most secure. Am i on the right track here? many thanks, matt ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
