key unloading

[Christian Hergert <christian hergert me>]

Hi,

Sorry if there is a clear answer to this somewhere, but I couldn't find 
it in documentation or quick look through the code.
Is there a way to unload all keys, perhaps via a DBus call or command 
line option?
I ask, because what I would like is for all my keys to be unloaded upon 
suspend/hibernate/etc. (Maybe this happens already and by logging in 
they are reloaded?)
I assume I could just kill the seahorse process, but that seems a bit 
heavy-handed. It might be nice to have a shell extension or something 
that simply unloads these during suspend (or a GSetting?) :)
Longer term, I'd like my LUKS/dm-crypt password unloaded, but will take 
a lot more complex Linux kernel/plymouth/wayland dancing.
Cheers!
