Thank you for the patch.

Thanks a lot.

Not yet fully finished, but it's better for me to put it now:

I leave this open as ticket for the rest ?

Here is my fix:

Here is my change for libkleo Japanese Translation:

My understanding is that: selftest in Kleo does call assuan_socket_connect (possibly in kleopatra/src/libkleopatraclient/core/command.cpp), and it didn't send nonce correctly.

I found an issue in the assuan code of client side. This might be the cause of the server failure for nonce.

Well, not our bug... it's a kind of support question and answer:

Pushed the change.

Ah, I had not done git pull for a week, and I didn't realize your patch.

Something like this should fix the behavior:

             continue;
           if ( s && (opts[ordtbl[i]].flags & ARGPARSE_OPT_HEADER))

I will push this change:

I figured out the situation.

Ah, I found that we have very bad example use case in tests/t-mpi-point.c. This should be fixed at first.

Thank you for your report. IIUC, it is called unexpected way, like invalid/wrong KEYPARMS. Possibly, KEYPARMS == NULL, or something like that.

Here is my try of next, after 0001.

Here is my try:

AFAIU, gpgrt-config works well now for the multilib MinGW target.

Thank you for your report.
Please look T6204.
Closed as duplicate.

Fixed in rG8e8971403f75: w32: Fix gnupg_unsetenv..

Pushed the change.

Now, the use of AM_PATH_GPGME_PTHREAD shows warning. Also I update the documentation.

Modern way for license notice seems use of URL: https://www.gnu.org/prep/maintain/maintain.html#License-Notices-for-Code

@ametzler1 Thanks a lot for your help.

Sorry, it looks like no problem.

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

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)

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.
