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.

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.

--
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.

* g10/keygen.c (print_key_flags): Print "RENC" if set.
(ask_key_flags_with_mask): Remove RENC from the possible set of
usages. Add a direct way to set it iff the key is encryption capable.
--
This could be done by using "set your own capabilities" for an RSA
key. In fact it was always set in this case.

algos. Implement for Kyber.

This also adds some fixmes which we eventually need to address.

* agent/command.c (cmd_pkdecrypt): Fix comparison.
* agent/agent.h (enum kemids): Rename type and strip trailing comma.
* agent/pkdecrypt.c (agent_hybrid_pgp_kem_decrypt): Allow building
with Libgcrypt < 1.11
--
Eventually we should change the libgcrypt requirement in configure.
* g10/call-agent.c (agent_probe_any_secret_key): Act on --quiet.
--
When using the extra-socket this disagnostic will be printed because a
listing of all secret keys is not allowed by a remote gpg.
* g10/keygen.c (print_key_flags): Print "RENC" if set.
(ask_key_flags_with_mask): Remove RENC from the possible set of
usages. Add a direct way to set it iff the key is encryption capable.

* common/openpgpdefs.h (PUBKEY_ALGO_KY768_25519): Remove.
(PUBKEY_ALGO_KY1024_448): Remove.

(gpg_mpi_write_opaque_32): New.
(do_key): Support Kyber keys using the revised format.

* g10/parse-packet.c (read_octet_string): Add arg nbytes so support
reading with a length prefix. Adjust callers.

Note that this callback is not yet used.
(ecckey_from_sexp): Add optional arg sexp2 and use it for Kyber.
Change callers.

(common_gen): Add arg keyparms2, change callers, and support Kyber.
(gen_kyber): New.
(get_keysize_range): Support Kyber.
(fixup_keysize): Simplify and support Kyber.
(do_create): Handle Kyber.
(parse_key_parameter_part): Remove algo strings "ky768" and "ky1024"
and add a generic "kyber" with default parameters.
--
This uses a revised format which is more aligned with the usual
OpenPGP structure. A lot of things are still missing. For example
support for handling two keygrips and checking both of them in a -K
listing. There is also only ky768_bp384 as fixed algorithm for now.
No passphrase for the Kyber part of the dual algorithm is on purpose.
A test was done using
gpg --quick-gen-key pqc1 nistp256
and then running
gpg -v --quick-add-key <fingerprint> kyber
which creates a v5 subkey on a v4 primary key. A second test using
gpg --quick-gen-key pqc2 Ed448
followed by a --quick-add-key created a v5 key with a v5 subkey.

* common/openpgp-oid.c (oidtable): Add column "abbr" and set them for
Brainpool.
(openpgp_oid_to_curve): Rename arg "canon" to "mode" and implement
mode 2.
--
For dual algorithms (PQC) we need shorter versions of brainpool to
avoid names which otherwise might be capped when printed.
* common/kmac.c (compute_kmac256): Return an error for older gcrypt
versions.
--
Except for the new KEM module there is no hard requirement for
libgcrypt 1.11 *yet*.

An example for an extension would be extKeyUsage for authentication:
