gpg maybe? It doesn't have a -w option, but it does have pgp compatibility modes. -- Jim Sabatke Hire Me!! - See my resume at http://my.execpc.com/~jsabatke Do not meddle in the affairs of Dragons, for you are crunchy and good with ketchup.

On my KDE desktop under SuSE 8.2 there is a 'Shredder' icon which invokes kgpg with 'kgpg -X %U', so if you are using KDE this may do the job for you. Regards, -- Andreas Philipp Noema Ltda. Bogotá, D.C. - Colombia

gpg does not have a wipe command. For single files, e.g. a list of usernames and password on Web sites, I find using vim with the command below in ~/.vimrc works. I keep the file always encrypted on disk and use vim to view or edit it. For bulk erasing, use the wipe command. Note: I don't understand vim config files, so you are on your own for support.
