Use of mpi_cmp is now being fixed, by providing _gcry_mpih_cmp_lli function.
Along with that, we need to fix use of mpi_cmp_ui, since it's skips earlier depending its limbs.

Just a note that i've tested this and --clearsign appears to be problematic for 2.4.7 as well as 2.2.40.

Another thing (should definitely go into a new ticket if we want to do something regarding this):

Again for Gpg4win 4.4.0, this time with better attention (and definitively encryption only):

a demonstration:

I was referring to your comment earlier in this very issue:

Okay. We now replace the standard Breeze icon of kleopatra with the red head for vsd and with a new blue head for gpd. The replacements are used for the About action and in the About dialog, but kwin (X11) insists on using the standard icon as window icon. And the system tray also shows the standard symbolic Breeze icon instead of the replacements. strace shows that the replacement icons embedded in the AppImage are loaded. No idea why kwin and the system tray still use the standard icons.

Here we go:

Shorter version:

Possible explanation text for the user regarding the background of the question (probably to long):

Thanks.

Where do you find a statement that --keyring is deprecated? I planned to to remove it with 2.1 but there were too many requests to keep it and live with the problems of multiple keyrings. Thus the option stayed, it is just so that in addition to pubring.gpg and pubring.gpg we now also have the option for keyboxd - which is the default for new installations.

FWIW, for gpd and vsd we should use a different icon (blue head for gpd and red head for vsd)

Alright, my above putenv option won't work because it modifies the session environment and thus needs to be run for each gpg-agent session (connection). Adding a putenv_startrup option would help here but this way each connection could chnage the environment - also not good. In the end a way to modify the used environment variables, as you suggested, is a better way.

Yes, the workaround is to use a pinentry wrapper script that sets the value back to the correct one and then invokes the real pinentry.

Kleopatra with Breeze style:

Looks the same in VSD 3.3.0 ans in Gpg4win:

This is the current (VSD 3.3.0) state for Japanese (with German as fallback):

I'm not going to keep re-opening a ticket that you keep closing. So i'm just going to state here what i believe to be the upstream intent is. If you think this is wrong, i'd love a clarification. I believe that "deprecated" means that the GnuPG project believes that an option or configuration choice should not be used, and will eventually go away.

The actual cause here was that right before storing the imported key we need to decide whether to insert or update a keyblock. For this we need to lookup the key in our database and the lookup function does the usual thing by looking at any fingerprint. This is wrong: Here we need to lookup only by primary fingerprint. This is what the above patches do.
