The provided change does not look like fixing the problem for me. The path to gpgconf is still wrong and I am getting the same error both with master and with the patched tarballs:

I can't find a url to download gnupg 2.3.8 for windows is it possible to know when gpg4win v.4.0.4 is out which fixes this bug? because currently on windows systems I am stuck using yubikey.

It is unlikely that the tofu stuff will get into widespread use in the 2.2 version - if at all.

As 2.3.7 was released on the 11th of July, see https://lists.gnupg.org/pipermail/gnupg-announce/2022q3/000474.html
I guess that this issue should be closed and some issues moved to one with 2.3.8.

Probably, PIPE_REJECT_REMOTE_CLIENTS mode and lpSecurityAttributes=NULL is OK.

Here is the parser output:

$ python3 sd.py --type=pipe "D:P(A;;GA;;;SY)(A;;GA;;;BA)(A;;0x12019b;;;AU)"
D:P(A;;GA;;;SY)(A;;GA;;;BA)(A;;0x12019b;;;AU)
    Discretionary ACL: P(A;;GA;;;SY)(A;;GA;;;BA)(A;;0x12019b;;;AU)
        Flags: P: SE_DACL_PROTECTED (Blocks inheritance of parent's ACEs)

I think that the last argument of CreateNamedPipeA can limit the access to the named pipe.

Here is a patch to implement the functionality with --enable-win32-openssh-support.

Backported for for 2.2.37

I just confirmed that firmware 5.4.3 works fine with the changes (to be 2.2.37 and 2.3.8).

as of 2.3.7 (which I just updated to) this works. ticket can be closed

Please give us more information.

• Do you change SSH program?
  • If so, please check if adding configuration https://dev.gnupg.org/T5935#157674 for ssh works.
• Do you mean, reinstalling gpg 2.3.4 fixes your issue?
• Are you using with smartcard/token? Which one (Yubikey/Zeitcontrol/Gnuk), if it's the case?

Does Yubico furnish you with devices for test...

Thanks @gniibe. Does Yubico furnish you with devices for test, or did you have to order that at your own/the project's expense?

I'm going to backport this to 2.2, as it found useful.

It's in 2.3.7.

Changed the tags and the title.

Fixed in 2.3.7.

Fixed in 2.3.7.

Due to vacation the review may take some time.

Any chance someone is able to review the posted patch?

Let me know how best to submit it

I tried to submit the below patch to gnupg-devel@lists.gnupg.org, but get an Unrouteable address error. Let me know how best to submit it

The first ideas sounds best to me. Patches please to the mailing list.

FIPS 140-3 (https://csrc.nist.gov/Projects/cryptographic-module-validation-program/fips-140-3-standards) points to SP 800-140Dr1 (https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-140Dr1.pdf) to list acceptable "Security Parameter Generation and Establishment Methods". From this document, RFC 5869 (i.e., HKDF with the counter at the end) can be reached via two paths:

This is a reasonable feature, however it should be noted that this implies a fairly large metadata leak: You are essentially adding a URI to signatures that will be pinged on signature verification.

I don't see why this is a child task of T6020: the features are similar, but they don't actually impact each other in any way.

I pushed the change needed for GnuPG to t5964 branch.
See: https://dev.gnupg.org/rGc281bd94349e4f7997a89927aaa2c2f45004b902

Added HKDF implementation to master.

Here is a test signature with long notation data. During verification gpg faults when emitting the NOTATION_DATA lines.

Thank you. Applied.

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:

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

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

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.

@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 learned that it's now called "OneStep KDF" in SP 800-56Cr2.
It's "SSKDF" in OpenSSL (Single Step KDF, perhaps).

Related problem exists with the modern ESIGN application. I think I fixed that but the whole Telesec eIDAS QES case needs more work.

The changes have been applied with Werner's suggested improvement with revision rG35b17550706c: gpg: Look up user ID to revoke by UID hash

Any progress on how the solution for this have been considered? Thanks.

At first, we need to add/enhance new API for KDF in libgcrypt. Currently, the term "KDF" in libgcrypt is used with narrower focus, that is, only for password->key KDF.

Lets implement it for 2.3

Thank you, @gniibe. That's what I was missing: installing libsqlite3-dev made the difference.

Pushed the fix.

You need to install a package like sqlite-devel or libsqlite3-dev, so that you can have development header files and library (sqlite3*.h and libsqite3.so) and pkgconfig file (pkgconfig/sqlite3.pc).

Yes, I saw that in the logs and installed those packages. Now I have sqlite and sqlite3 in /usr/bin, but that doesn't seem to have changed anything.

the link's target doesn't exist

Yes, of course I did that. The error output I included followed the sequence

Please do make at first before invoking make check. It creates symbolic links for executables.

When we implemented this first, Libgcrypt had no appropriate KDF support. I recall that I considered to change this but it turned out the for 2.2 the changes are too large. For 2.3 we will consider such a change.

Fixed in GnuPG 2.3.5.

Nitrokey Start uses Gnuk as its firmware. You need to upgrade its firmware to version 1.2.16 or newer.
Please note that when upgrading the firmware, your keys will be removed.

Its a nitrokey start. I gave it another spin just to make sure, and again when updating to openssh 9.0 and "gpg (GnuPG) 2.3.6-unknown", it fails (again with careful gpgconf --kill gpg-agent etc. Double checked the downloaded source code by arch's makepkg, appears to have that patch applied. Also tried adding -o KexAlgorithms=-sntrup761x25519-sha512@openssh.com to the ssh command, which didn't help.

Please describe what token is used. For my use cases with rGe8fb8e2b3e66: scd: Don't inhibit SSH authentication for larger data if it can., both of Gnuk (>= 1.2.16) and Yubikey (>= 5) work well.

this looks similar to https://dev.gnupg.org/T5935 and https://bugs.debian.org/1008573
