How to create a command-line password locker
Like many people, I have too many passwords to remember. To keep them straight, I wrote a simple password locker script using dialog and GnuPG (GNU Privacy Guard). The script prompts the user for a master password using a dialog box, unencrypts a file that holds a list of passwords, and opens the file in a text editor. When the editor is closed, the script re-encrypts the password file.
Dialog is an ncurses-based utility for providing text-based message and input boxes. GnuPG is a free implementation of the OpenPGP standard. Both applications are available as binary packages on Debian-based systems.
