So because I use some thing that "almost everyone does not use" - but something that you distribute you do not even want to fix it?

You are using the basic pinnentry which comes as part of the basic installer. Almost everyone does not use this but Gpg4win which has a real pinentry. See http://gpg4win.org You don;t need the program statement then because gpg is installed in the PATH.

Sorry, it looks like no problem.

Implications are... you won't be possible to use new protocols introduced by newer OpenSSH:

Thanks. Adding 'PubkeyAuthentication unbound' to my ~/.ssh/config seems to workaround it for me on openssh-9.1p1-3 (arch). I don't quite follow what the implications of that setting are though.

Thank you for the bug report and your suggestion.

In my cases (tested with 9.1), here are the length of data to be signed by ssh-agent (emulation by gpg-agent).

• 164 bytes: Both features disabled by: ssh -o KexAlgorithms=-sntrup761x25519-sha512@openssh.com -o PubkeyAuthentication=unbound
• 192 bytes: Unbound only by: ssh -o PubkeyAuthentication=unbound
• 298 bytes: No Post Quantum only by: ssh -o KexAlgorithms=-sntrup761x25519-sha512@openssh.com
• 330 bytes: Both features enabled (no options)

To test this you need a key with a subkey (including the primary key) that is marked for signing and authentication, but not for encryption. Open the Subkey dialog, insert an OpenPGP smart card, right-click this subkey and select Transfer to card. Select the Authentication slot when you are asked which card slot the key should be written to.

Actually we have two gpgme versions in gpg4win because gnupg is a "sub"-installer inside of gpg4win and it comes with its own gpgme. That gpgme is the release version but the one used by gpg4win's kleopatra is often a newer snapshot.

Here is the patch which will go into the next release

Subject: [PATCH] Fix an integer overflow in the CRL signature parser.

ok, works as described.

thank you, works for me.

Thank you, looks good to me.

[CMS]
AllowSigning=false

hides the S/MIME-Sign... entry in the Clipboard menu (in the Tools menu and the context menu of the system tray icon).

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

AllowCertificateCreation=false

works as described.

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

works

I tested with openssh 9.1. When I add -o PubkeyAuthentication=unbound, I can make the length of data smaller.

Please use gpgme.pc to configure your build. Your options are:
(1) With Autoconf:
(1-1) Use pkg.m4 and PKG_CHECK_MODULES (which uses pkg-config to access gpgme.pc)
(1-2) Use gpgme.m4 and AM_PATH_GPGME (which uses gpgrt-config to access gpgme.pc)
(2) Or... use pkg-config to access gpgme.pc.

On Windows, closing/inheriting handles is different to POSIX.

I put rCc34c9e70055e: fips: Mark AES key wrapping as approved. under this task, so that it can be referred in the release note.

Let me describe the changes recorded in this task.

We need to do this also for CHANGE REFERENCE DATA - however, there should be an extra option so that we can debug this despite of the redacting.
