GNOME Bugzilla – Bug 727815
gnome-keyring-daemon should not cache gpg keys indefinitely
Last modified: 2016-02-23 09:56:50 UTC
The gpg agent offered by gnome-keyring-daemon caches keys until logout. I think this is a really bad idea: I have a gpg key that I use to encrypt some sensitive stuff, I don't want it to remain cached for hours. Note that the gnu gpg-agent forgets the key after a certain amount of time (600 seconds by default).
gnome-keyring no longer implements a gpg-agent. The gnupg agent and pinentry have been better integrated with GNOME. https://mail.gnome.org/archives/distributor-list/2015-August/msg00000.html
