Mostly working :)

The file path of the group config file in line
https://dev.gnupg.org/source/g4wt/browse/master/src/resolver/resolver.cpp$171
has to be changed to the one in line
https://dev.gnupg.org/source/kleo/browse/master/src/kleopatraapplication.cpp$355 .
It may be best to add a function returning the default path to libkleo. Or to use the new path by default if no other path is passed to the c'tor of KeyGroupConfig. It's unfortunate that the path is GNUPGHOME/kleopatra/kleopatragroupsrc although the groups are also used by GpgOL and they should likely also be supported/used by KMail.

https://invent.kde.org/pim/kleopatra/-/merge_requests/355 makes both components use the same tooltips; we can then change both when we decide on what exactly to show in the tooltips in general

One year later, I also did translation work for kleo and libkleo, which are pushed by Andre.
So, closing this task.

Fixed in 2.5.2.

Yeah, I guess we can word this a bit less spec-like. It has more or less the same purpose as an admin PIN except that it's a 128 (?) bit key. And, if I understand correctly, it can also be used by the (admin) user to make sure they are talking to the correct card (if all cards are provisioned with unique keys). Kleopatra automatically tries to authenticate with the standard key so that we never see the prompt for the key unless we have changed it.

i see the tag has been published now, thanks! Given that this is an ELTS release, I'm assuming that the lack of a gnupg-2.2.46.tar.bz2 file on https://gnupg.org/ftp/gcrypt/gnupg/ is deliberate.

glad it was useful!
