gpg tries to find the "best" key using get_best_pubkey_byname (https://dev.gnupg.org/source/gnupg/browse/master/g10/getkey.c$1507), but the applied rules are not clearly documented in one place.

Because it's the library which refuses null passphrase as input, only possible options are either:

Backported to GnuPG 2.2.

Added --enable-maintainer-mode to ./configure

Applied the changes.

Now, it also supports a reader with pinpad.

A use case for this is to allow the use of S/MIME for de-vs mode and for standard mode while clearly indicating compliant certificates. As of now all certificates matching compliant algorithms are indicated as compliant. The new flag could be used to distinguish between them.

The suffix .kgrp has been added as default filter for the import with revision rKLEOPATRA5c4d3a80d5a9: Allow the export of certificate groups.

Thanks.

Created gniibe/t5912 branch.
It works for me.

I can only find this one: https://github.com/patrickfav/singlestep-kdf/wiki/NIST-SP-800-56C-Rev1:-Non-Official-Test-Vectors

Can you do a search on the command line:

Updated (with T6012):

Thanks @jukivili , Here is the changelog,

Thanks for updated patch. I'm travelling next week and have time to check it closely only after I'm back. On quick glance, it looks good. What is also needed is the changelog for git commit log.

nice, that's great news! I'll have to try it out when I get a chance.

GpgOL konfigurieren - Version 2.5.3
Gpg4win 4.0.2

You may want to write gnupg-users@gnupg.org to tell about this tool. That seems to be a better place with a larger audience. Or you add it to wiki.gnupg.org.

See https://github.com/google/xsecurelock/blob/master/helpers/authproto.h
for the interaction between xsecurelock and the helper.

I changed gpg-connect-agent (added --unbuffered option) so that we can write shell script interacting gpg-agent.

Wrote a shell script for xsecurelock's authproto (helper executable):

Funnily I created a file dirmngr/rfc3161.c last Sunday. I can't tell how long it will take but I am definitely interested in using GnuPG to create qualified signatures. Timestamp support is at least good for testing.

Welche Gpg4win Version?
Welche Windows und Outlook Version?
Ist das die erste Installation oder ein Update?

Thanks @jukivili. I have never thought of interleaving with interger poly1305 operation and that's a good suggestion. Will think about that one.

@werner There's renewed interest with protecting supply chains. GnuPG is used by a lot of open source systems. Is it possible to bump the priority on this?

I meant interleaving integer register based 1xPoly1305 with 8xChacha20 as is done for 4xChacha20 in cipher/chacha20-ppc.c (interleaved so that for each 4xChaCha20 processed, 4 blocks of 1xPoly1305 is executed). Quite often microarchitectures have separate execution units for integer registers and vector registers and then it makes sense to interleave integer-poly1305 with vector-chacha20 as algorithms do not end up competing for same execution resources. Interleaving vector-poly1305 and vector-chacha20 is not likely to give performance increase (and likely to run problems with running out of vector registers).

HI @jukivili , Thanks for the updates. For f14-f31 registers that was my mistake that did not think floating point will be used. Will correct that. For poly1305, it can be used on ARCH_3.0 so checking use_p10 doesn't seem to be necessary but I can include that as well.
