A simple password manager using GPG written in POSIX sh.

• Written in safe and shellcheck compliant POSIX sh.
• Only 120~ LOC (minus blank lines and comments).
• Compatible with pass's password store.
• Clears the clipboard after a timeout.
• Configurable password generation using /dev/urandom.
• Guards against set -x, ps and /proc leakage.
• Easily extendible through the shell.

This is the first package I'm contributing so any help/advice is appreciated.
