Pushed the fix for exporting OpenPGP v5 key: rG57dce1ee62c2: common,gpg,scd,sm: Fix for Curve25519 OID supporting new and old.

Backported for gpg4win 4.x

When I last talked about this ticket I had not thought of the fact that we need to have this in some kleowrap wrapper and that currently stdout and stderr are not printed in a process which forwards its call to an already running kleopatra.

I thought about this and any change here has a regression risk and the release is already overdue. If we change this now as a band aid before a release with keyboxd we really need this only for one release.

Regardless of the migration. At least we need to set GNUPGHOME early in Kleopatras main to the value returned by GpgME so that the qt.conf patch works in KF6.

Andre, didn't we conclude that there's nothing worth migrating except the groups configuration (which is migrated)?

I see no commits that change the behaviour or do the migration. Then this is not fixed. To clarify. For me this issue is about General config files of KDE / Qt. Not only about the kleopatragroupsrc Since the kleopatragroupsrc was fixed in the last release already.
In the state I left it for VSD 3.3 (master) qt.conf is only written for Gpg4win. And not for VS-Desktop. So testing with Gpg4win has different results. This was the underlying reason since qt.conf was written with FileWrite and not packaged. I only changed that in Gpg4win master.

With the new patch you get this now:

[GNUPG:] KEY_CONSIDERED F40ADB902B24264AA42E50BF92EDB04BFF325CF3 1
[GNUPG:] ERROR add_adsk 53
gpg: key "F40ADB902B24264AA42E50BF92EDB04BFF325CF3!" not found: Unusable public key
gpg: Did you specify the fingerprint of a subkey?
[GNUPG:] FAILURE gpg-exit 33554433

Yes, gpg logs "invalid ADSK ... specified", but it doesn't emit a status error. This needs to be changed in gpg.

Tested with VS-Desktop-3.2.94.2-Beta.
Works as expected on the cli.

works for VS-Desktop-3.2.94.2-Beta (Beta for VSD 3.2.4)

Test with gpg4win-Beta-50 shows the same as described in the last comment.

tested with gpg4win-Beta-50:
works as described in https://dev.gnupg.org/T6866#179915

Test on a dedicated Windows box (T 460, i5-6300U@2.40GHz, harddisk):

gpg4win-Beta-50:
Columns are now displayed as expected with a fresh installation, too.

Tested with gpg4win-beta-50:
Adding a subkey works, its possible to add A, E or S subkeys with different algorithms and expiration dates.

I knew that we'd need something like D604 when I saw rM409e31458227, but then I forgot about it. :/

Looks good! Thanks!

closing this ticket as duplicate as adding and changing expiry works.
Revocation of a single subkey is not yet possible in Kleopara, though

should be fixed with D604

As we now have tabs for the subkeys this task is obsolete, really. Its useful as a parent ticket though.

Overall effect of these changes tested on a small Windows VM is only 47 -> 26 seconds. Did also tests with --kbx-buffer-size but that does not make it better than the default, either.
