possible? maybe, i don't know .. but if security is your concern, you _really_ don't want to do that .. If you can read the passwords out to replace them, then obviously anyone can read them. They'd probably pop right up if the exe was run through the standard *nix
strings utility.
Also, wherever you store them, be sure to not store plain text passwords -- use
Digest::MD5 or some other hashing techinique.
