My actual plan is to rework the imp[ort/export of secret keys to gpg-agent. Right now gpg-agent has knowledge of OpenPGP for import/export. This is not good and the required conversion should be moved to a helper tools for easier testing and to have this out of the gpg-agent process. For Kyber we right now don't use any conversion mut store the secret keys in gpg-agent's native format. Thus the passphrase is not necessary. We need to figure out why we have this problem here.

Merged, manually.

This ticket is explicitly about Kleopatra included in Gpg4win.

To reproduce the hang, a loop will suffice (usually happens within the first 15 times, once it needed 50 runs):

This is still open. It cannot be tested because Gpg4win still doesn't use KIO::move on Windows (because the above patch has not yet been merged).

There's no other configuration, this happens with a clean gnupghome with one smime cert + root cert and the above gpgsm.conf (output on stdin/stderr):

I think this is still open (and requires T6537: Make KIO::move work on Windows when moving between different partitions).

This is not yet fixed. KDE still applies a patch to gpgmepp (and gpgmeqt) to ifdef a few GCCisms.

@werner I added an implementation https://dev.gnupg.org/D622
that matches Linux behavior and avoids the message about secure memory not being supported on Windows. The change is scoped to the pinentry tool and intentionally follows Linux behavior. Does this approach look reasonable to you?

Reconsidering this all I don't think it makes any sense to distinguish between (-1) and GPG_ERR_INV_PACKET. We use (-1) for a too short read of the hashed or unhashed area (premature eof). INV_PACKET is for unknown versions, too much data (arbitrary limit), bad parameters, and underflow. Let's forget my previous comment and always use INV_PACKET.

I think "O" is a better key:

We need to change the accelerator. Right now gpg-agent uses
