Usage

When PolKit requests authentication, mini-polkit runs your command, reads the stdout as the password, then securely passes it to PolKit via D-Bus — thats it :3

To show the PolKit message inside your prompt, use {{MESSAGE}}:

mini-polkit "zenity --password --title='{{MESSAGE}}'"

As long as your tool writes the password to stdout, you're good.

Run mini-polkit in the background (e.g. using &), to make it act as a full-time agent

mini-polkit "zenity --password" &

You can autostart it via .xinitrc, .bash_profile, systemd or whatever you like.

Installation

Clone, build and install manually:

(deps. gcc, make, pkg-config, polkit-agent-1, glib->v2.0)

git clone https://github.com/cyber-amr/mini-polkit.git
cd mini-polkit
doas make install

Security Notes

Password is securely passed to PolicyKit via DBus and wrecked right afterwards from memory.
Input is read from stdin to avoid command-line exposure.
It is your responsibility to ensure the prompt tool handles input securely (e.g., dmenu with -P, rofi with -password).
