ok, works as described.

I have tried all 3 settings (in %APPDATA%\kleopatrarc):

AllowCertificateCreation=false

works as described.

Keyserver option is no longer shown in the OpenPGP tab of GnuPG System

works

works as described by Ingo

works as advertised

works as proposed by werner.

If a certificate is in more than one group, this will not work...

Hidden where?

works

Well, the picture given as example above looks exactly as before if I choose a key by clicking on it. But at least it changes after hitting return or switching to the next line, so it's an improvement.

I see no change in the reported behavior:

Does the recipient know the public key that was used for encryption?

The data from the above output was additionally OpenPGP encrypted to self.
The "not compliant" message only shows when the data is additionally encrypted to a public key.

well, when creating openPGP keys with kleopatra I did not see any hints. I do not think that the issue would be vaild for password based encryption. There the common usecase is autogeneration, anyway

also, in the recipient tab the "encrypt with passphrase" option is at the very bottom and so far away from the other options that it is easily overlooked, if the window is fullsized.

it seems to be a GnuPG-VSD packaging issue, then

Its an issue of cursor position. If one either deletes or inputs a a character anywhere in the password string, the cursor always jumps to the end of the string.
