@jukivili Thanks a lot. Please push the change to 1.10 branch and master.

Thank you for your report.

Ah... it fails by make check because it does change the text in tests/basic.c which requires update of hash value.
I'm going to take care of this regressions.

Thank you. All applied and pushed to master.

In 2.4, a user need to specify disable-ccid in scdaemon.conf when scdaemon is built with integrated CCID driver (using libusb) but the user wants to use PC/SC driver instead.

It's true that for KEYTOCARD command, there is optional argument for ECDH.
My point is that for PKDECRYPT command, it will be needed to add mechanism for getting such a parameter (when we use KEM API in gpg-agent).

Considering the design of gpg-agent which focuses on private key operations and data, it would be better to enhance the gpg-agent protocol to inquire public key data of any format defined by the client (including ECDH KDF parameters of OpenPGP). I mean, instead of storing data in the key file (originally designed for private key + some additional data), we will enhance the protocol.

Applied to 2.4, too.

To align the documentation of GnuPG, we should not use GNUPGHOME in FILES section.
It may be controlled by --homedir as well as GNUPGHOME.
GNUPGHOME is addressed in the ENVIRONMENT section, so, I don't think it makes sense using $GNUPGHOME}/trustedkeys.kbx.

Thank you. Applied and pushed in: rG260004747016: gpgv: Update used keyrings in doc FILES section

@item handling with @table has been pushed.

RSA improvement is not that worth now.

OK. When we will need and do, I will open new one.

The fix is in 1.10.3.

Fix is in 1.10.3.

I learned about how @item is handled by TeX. By @table command, user specifies how to handle the item line. In the case of GnuPG, it is like:

@table @gnupgtabopt
@item --version
...
@item --help

(Emacs uses @table @samp, while GCC uses @table @gcctabopt.)
And @gnupgtabopt is a macro which is expanded to @code{\body\}

I think that tried_password_cache in the documentation is wrong. The text:

and @code{tried_password_cache} is false

Pushed the change to master/2.4.

I guess that it's a case of specifying static passphrase. If so, here is the patch:

(I also found similar case for gpg as well as gpgsm.)

Pushed the changes for ...sc_op_failure routines to master/2.4.

We would need to revise tools/card-call-scd.c:status_sc_op_failure and g10/card-util.c:write_sc_op_status to catch GPG_ERR_PIN_BLOCKED and GOG_ERR_NO_RESET_CODE.

I found two places in scdaemon which return GPG_ERR_BAD_PIN. GPG_ERR_PIN_BLOCKED is relevant here.

Possible approach for source texinfo files and yat2m would be:

@desultory Thank you for your report.
Please open a new ticket for your problem. If you can, please show the result of https://dev.gnupg.org/T5963#157724

I found a regression for @item --version; It emits \[en]version for roff.

Pushed my fix to support them.

In master, when fixing padding issue, libgcrypt/src/const-time.h is just introduced.
I will replace your functions.

For length information, we can find that Simon's patch (let me call it v1) has length argument:

@fse Thank you for your comment (quick ! :-).

Please send us patches (to this branch).

Pushed the change into kem-kyber branch.
