Please archive libcryptui
Please archive https://gitlab.gnome.org/GNOME/libcryptui as it's really been dead in the water for several years. For GTK3, it was succeeded by libgcr.
It also exposes a D-Bus service https://gitlab.gnome.org/GNOME/libcryptui/-/blob/master/daemon/seahorse-service.xml which looks like it's seahorse, but it's not. People have been mentioning this in issues in seahorse, which has been pulled away from that service a long time ago
