Keepassxc: Add '--lock' option to keepassxc executable

[sriedel]

Summary

Add a command to keepassxc-cli that will lock databases of running keepassxc instances.

Desired Behavior

Invoking keepassxc-cli lock (or similar) will lock all running instances of keepassxc of the user invoking the command.

Context

I want to write scripts that lock the database when certain conditions occur. For example when suspending the machine, or when locking the screen (the auto-locking when locking the desktop doesn't seem to work under wayland), or even when the signal of the bluetooth connection to my cellphone gets too weak, indicating I moved away from my machine.

[droidmonkey]

The cli and the desktop app have no communication between each other. I prefer to keep it that way. The proper way to do this is to add the --lock command to keepassxc itself. Single instance will handle the lock message.

[sriedel]

I was not aware of the non-communication part, as long as it's possible for me to lock the database non-interactively I'd be fine with whatever alternative works best for the project :)

If you're able to use dbus, you can use this command per the Using DBus with KeePassXC wiki page:

qdbus org.keepassxc.KeePassXC.MainWindow /keepassxc org.keepassxc.KeePassXC.MainWindow.lockAllDatabases

I'll have a look into that, at first glance that would be sufficient for my purposes. Thanks!

qdbus org.keepassxc.KeePassXC.MainWindow /keepassxc org.keepassxc.KeePassXC.MainWindow.lockAllDatabases

The object name is not the same as the service name. Command should be

qdbus org.keepassxc.KeePassXC.MainWindow /keepassxc org.keepassxc.MainWindow.lockAllDatabases
