Still unresolved...

Or... it could be a feature, not bug, so that failure of -e -r someone can be examined by --locate-keys someone.

Let me clarify the point.

GnuPG ships a non-PKI certificate, specifically to authenticate hkps.pool.sks-keyservers.net. Now due to an implementation detail, this has been shown to potentially lead to authentication of other domains by this certificate, if a maintainer changes the default keyserver via the DIRMNGR_DEFAULT_KEYSERVER variable in configure.ac. Now arguably, this variable isn't exposed via ./configure, so it's not "officially" configurable - but evidently maintainers do want to change it. A trivial one-line patch was supplied to change the unintended and potentially security-problematic behavior into the (I believe) obviously intended one.

I think that we should apply further change:

diff --git a/g10/getkey.c b/g10/getkey.c
index 077209415..1c337149c 100644

@@ -1369,7 +1369,7 @@ get_best_pubkey_byname (ctrl_t ctrl, enum get_pubkey_modes mode,

I found more wrong cases of get_best_pubkey_byname.
For ranking results,
(1) It may return non-encryption primary key as the most relevant key, when its validity is higher.
(2) It may not select encryption primary key even if its creation time is newer.

I also think this makes the most sense.

In my opinion, --locate-key should locate encryption key.

@gniibe oh, I see thanks for pointing out precisely main the problem. I will check the hardware supply chain RoHS 2002/95/EC

There are some problems with the definition of --locate-key. Further discussion required.

@pow, thanks for a reference. But problem here is that there are multiple products with same name.

@werner Yes, that sounds great, and would help already a lot, but extending it for card keys would be optimal. Thanks for your work.

In master (to be 2.3) you can add a Label: line into the sub key file of on-disk keys. I use this for quite some time now to show me alabel for my on-disk ssh keys so that I known which one was requested. We can and should extend this to card keys.

Same here, having YubiKeys and on-disk ssh keys from several computers, it is a bit a pain not to know which key is actually used. Any chances to get at least an update via manual editing of the comment?

I've also noticed this issue on windows when trying to symlink %APPDATA%\gnupg to $HOME/.gnupg under msys32.

Dear Martin,

Not sure what I did wrong this time, but it's broken again - GPG will again prompt for the PIN on my computer instead of on the Gemalto Ezio Shield reader :(

I'm using GnuPG 2.2.4-1ubuntu1.2 with your patch applied:

I believe that constraint of ret_keyblock != NULL is OK.
Pushing the fix.
Perhaps, backport to 2.2 should be done, too.

I have the same effect if I send a signed text-only or HTML email using Outlook 365 and our Exchange 365 and if I view the mail on Outlook on Android. The mail shows no contents only the file. If I view the mail using Outlook 365 on my PC or Windows 10 Mail it looks fine.
If I address it also to my Microsoft account and my Gmail account (using all adresses in the TO: field of the same mail) the email looks normal in the Gmail Android app and (!) in Outlook for Android.
So the same mail - both in the same Outlook for Android app - looks correct in my Microsoft account inbox but only shows the file in my Exchange inbox - in the same Outlook App. Weird… Nokia 7 plus, Android 9, newest patch level (September 2019) and no updates in Google Play Store.
BTW: In Exchange 365 I configured the message flow, default remote domain (there is no other) to never to use Rich Text, always and only HTML.
