* tools/gpg-authcode-sign.sh: New.
* tools/Makefile.am (bin_SCRIPTS): Add that tool.
--
This script makes use of gpg anyway and thus it is best to have it
also installed with the gpg version used to cross-build our software.
The script was orginally developed for gpg4win.
* agent/call-scd.c (padding_info_cb): Allow NULL.
(agent_card_pkdecrypt): Likewise.

* agent/divert-tpm2.c (divert_tpm2_pkdecrypt): Likewise.
--
It's for RSA PKCD#1 encoding if the decrypt operation removes padding
or not. When caller knows it's not RSA, this information is no use
and it is better to allow NULL with the variable R_PADDING.

Note, this needs the very latest Libgcrypt to work properly
* g10/pkglue.c (do_encrypt_kem): Support cv25519 w/o 0x40
prefix. Support X448.
(ECC_POINT_LEN_MAX): New.
(ECC_HASH_LEN_MAX): New.
* common/openpgp-oid.c (oidtable): Support X448 KEM.
--
This needs more work. For example we should use a parameter table
like what we do in agent/pkdecrypt.c.
GnuPG-bug-id: 6815
* configure.ac (NEED_LIBGCRYPT_VERSION): Set to 1.11.0
* agent/pkdecrypt.c (struct ecc_params): Move constants to the top.
--
It does not make anymore sense to allow building with older Libgcrypt
versions. After all PQ key support is a major feature and for this we
need Libgcrypt.
* agent/pkdecrypt.c (composite_pgp_kem_decrypt): Care about
ML-KEM 512 and 1024.

* g10/options.h (LIST_SHOW_OWNERTRUST): New.
* g10/keylist.c (print_key_line): Show wonertrust and always show
whether a key is disabled.
* g10/gpg.c (parse_list_options): Add "show-ownertrust".
* g10/gpgv.c (get_ownertrust_string): Add stub.
* g10/test-stubs.c (get_ownertrust_string): Add stub.
--
Note that in a --with-colons listing the ownertrust has always been
emitted and the disabled state is marked in that listing with a
special 'D' usage.
* g10/gpg.c (oWithoutSubkeyFingerprint): New.
(opts): Add "without-subkey-fingerprint".
(main): Make --with-subkey-fingerprint the default. Implementation
the without option.
--
Given that the default for the keyid format is none, the subkey
fingerprints are important to do anything with a subkey. Thus we make
the old option the default and provide a new option to revert it.
* g10/build-packet.c (do_pubkey_enc): Support Kyber.
* g10/pkglue.c (do_encrypt_kem): Implement.
--
Note that the code does only work for ky768_cv25519 for now.
GnuPG-bug-id: 6815
* common/kem.c: Move constants to the top. Add some documentation.
* g10/pkglue.c (pk_encrypt): Add arguments session_key and factor code
out to ...
(do_encrypt_rsa_elg): here,
(do_encrypt_ecdh): and here,
(do_encrypt_kem): and here.
* g10/encrypt.c (write_pubkey_enc): Call with session key algorithm.

This makes it easier to review the code.
* scd/app-openpgp.c (get_cached_data): When it comes with
its tag and length for the constructed Data Object, remove
them.

* g10/pkglue.c (pk_encrypt): Remove superfluous arguments and reanem
variable rc to err.
* g10/encrypt.c (write_pubkey_enc): Adjust for this change.
--
We used to pass PK as well as information which could be taken
directly from PK. Using ERR instead of RC is just for more uniform
naming of variables.
* g10/packet.h (PKT_pubkey_enc): Add field seskey_algo.
(struct pubkey_enc_list): Ditto.
* g10/misc.c (pubkey_get_nenc): Change value for Kyber from 4 to 3.
* g10/parse-packet.c (parse_pubkeyenc): Store the Kyber algo in the
new field and adjust data. Do not store the length byte in data[2].
* g10/build-packet.c (do_pubkey_enc): Take the session algo for Kyber
from the new field.
* g10/encrypt.c (write_pubkey_enc): Ses the seskey_algo.
* g10/mainproc.c (proc_pubkey_enc): Copy it.
* g10/pubkey-enc.c (get_it): Support Kyber decryption.
* g10/seskey.c (encode_session_key): Handle Kyber different from ECDH.
--
Having always the single byte in the packet data than to store and
retrieve it from an MPI is much easier. Thus this patch changes the
original internal format. With this chnages decryption of the slighly
modified test data works now. See the bug tracker for test data.

* g10/seskey.c (encode_session_key): Handle Kyber session key like
ECDH. This is just a stub.
* g10/keygen.c (ecckey_from_sexp): Use the modern OID for cv25519.
(parse_key_parameter_part): Allow more Kyber variants.
--
Test by creating an ed25519 key and using
gpg --quick-add-key --batch --passphrase "" <fingerprint> <algo>
to create several subkeys. Tested with ALGOs:
kyber768
kyber1024
ky768_cv25519
ky768_bp256
kyber768_nistp256
ky1024_cv448
All curves capable of encryption should work.

--
This could be done by using "set your own capabilities" for an RSA
key. In fact it was always set in this case.
