Evaluating again, I'd like to change spawn functions like this one in libgpg-error:

@aheinecke What additional information do you need ?

I just moved Phabricator to a new machine and created separte certificates for files.gnupg.net and dev.gnupg.org.

You need to handle them in a correct way. Just checking with gpg is
not enough because you don't know what has been signed. You need to
look at the signed data which gpg gives you by using the --output
option. And there you see only the signed data and not the extra
"aaa" you added after having signed the plaintext. It is not
different from adding stuff before the -----BEGIN PGP SIGNED ... line.

Actually I am not sure whether this is really a bug and that the fix is needed. What has been signed and verified is what gpg has seen and what --output has written. For example a line in the cleartext format may read "- From my " but what actually has been signed was "From my". If a line has been truncated --output will write only the truncated and thus verified data and not what was in the cleartext format.

works as described by Ingo

works

The distinction between reader and card is not easy and PS/SC is also not helpful here. The user needs to resort to trial and error. With 2.3 things are much easier because we do not need to select the reader anymore.

works

Thanks. There should also be SPDX indentifiers everywhere.

works

Examining again, I realized that the current spawn API (not published yet, only available in libgpg-error master) is not that useful in general (or difficult to use), while it works somehow.

A workaround you can add the following line to ~/.ssh/config or /etc/ssh/ssh_config:

KexAlgorithms -sntrup761x25519-sha512@openssh.com

For me ssh -o KexAlgorithms=-sntrup761x25519-sha512@openssh.com ... does work as well.

works as advertised

Fixed, to be released with Gpg4win 4.0.5.

A workaround you can add the following line to ~/.ssh/config or /etc/ssh/ssh_config:

AFAIK, Microsoft stated that the value of a HANDLE will always fit into a DWORD; i.e. only the lower 32 bits are used even on a 64 bit Windows.

Now, we implemented fd passing on Windows in libassuan.
Note that the process identifier (represented by DWORD) and handle for a process (represented by HANDLE) are different things.

On the command line using:
gpg -o output.txt --decrypt "yourfile.asc"

Here is the change of GnuPG to use new spawn functions from libgpg-error:

Merged PIPE connection part into master.

ready for testing
