* g10/options.h (opt): Add show_only_session_key and turn
show_session_key into a bit flag.
* g10/gpg.c (oShowOnlySessionKey): New.
(opts): Add "show-only-session-key".
(main): Set flag.
* g10/mainproc.c (proc_encrypted): Handle the new option.
* g10/decrypt-data.c (decrypt_data): Ditto. Add compliance error flag
to the DECRYPTION_INFO status line.
--
This new option is somehow related to
GnuPG-bug-id: 1825
* g10/keygen.c (PQC_STD_KEY_PARAM): New.
(quickgen_set_para): Always store the provided NBITS.
(parse_key_parameter_string): Detect the special value "pqc".
(quick_generate_keypair): Ditto.
--
With this change we can finally do a
gpg --quick-gen-key --batch --passphrase='' foo@example.org pqc
and get a full key. Currently with a brainpoolp386r1 primary key and
a Kyber768_brainpoolp256 subkey.
* g10/getkey.c (lookup): Skip keys with unknown algos.
--
If the local store has private keys with an algorithm not supported by
thi version of gpg, gpg used to bail out. Thus decryption of proper
messages was not possible. This fix skips such secret keys.
* g10/keylist.c (print_revokers): Add arg with_colon, adjust callers,
add human printable format.
(list_keyblock_print): Call print_revokers.
--
Designated revokers were only printed in --with-colons mode. For
quick inspection of a key it is useful to see them right away.
* g10/options.h (opt): Move the definition of struct akl to global
scope.
* g10/keydb.h (enum get_pubkey_modes): Add GET_PUBKEY_TRY_LDAP.
* g10/getkey.c (get_pubkey_byname): Implement GET_PUBKEY_BYNAME.
* g10/keygen.c (prepare_desig_revoker): Use it here.
(prepare_adsk): and here.
--
The revoker key is required before we create it along with a new key.
This is because the we need to know the algo and also to make sure
that the key really exists.
GnuPG-bug-id: 7133
* g10/keyserver.c (keyserver_import_mbox): Add arg flags and change
callers.
(keyserver_import_ldap): Remove. It has always returned a not
implemented error since 2.1.
* g10/getkey.c (get_pubkey_byname): Repurpose LDAP to do basically the
same as KEYSERVER.
--
The old LDAP mechanism to locate a server via SRV records has long
been gone (since 2014) due to the dropping of the keyserver helpers.
The new purpose better reflects reality and can be used in
environments where keys are provided by an in-house LDAP server.
--
These are non-substantive corrections for minor spelling mistakes
within the GnuPG codebase.
With something like this applied to the codebase, and a judiciously
tuned spellchecker integrated as part of a standard test suite, it
should be possible to keep a uniform orthography within the project.
GnuPG-bug-id: 7116

simplify error handling.

(locate_one): Ditto.
(list_keyblock): Detect write error, print, and return it.
(list_keyblock_direct): Return error from list_keyblock.

GnuPG-bug-id: 6185
* g10/keygen.c (parse_key_parameter_part): Change Kyber defaults.
--
Also kyber1024 is now a shortcut for ky1024_bp384. This change is to
align it with the original wussler draft.
* g10/keygen.c (struct opaque_data_usage_and_pk): New.
(do_add_notation): New.
(keygen_add_key_flags_from_oduap): New.
(write_keybinding): Prepare for de-vs cplimance notation. Add a
notation to Kyber subkeys.
--
This code is based on the 2.2
commit b284412786
However the de-vs notation is currently ineffective as long as
Libgcrypt won't claim compliance.
The new notation fips203.ipd.2023-08-24 has been added to allow
detection of subkeys which have been crated with a pre-final FIPS203
spec for Kyber.
* common/openpgp-oid.c (oidtable): Support KEM for bp256 and bp384.
* g10/pkglue.c (do_encrypt_kem): Ditto.
--
GnuPG-bug-id: 6815
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
* 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/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.
* 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.
GnuPG-bug-id: 6815
* common/openpgp-oid.c (openpgp_is_curve_supported): Allow the
abbreviated curve name.
* g10/pkglue.c (pk_encrypt): Add debug output.
* 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.

* 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.
GnuPG-bug-id: 7072
* agent/cvt-openpgp.c (extract_private_key): Support Kyber algorithms.
* common/openpgp-oid.c (map_gcry_pk_to_openpgp): Map KEM to Kyber.

with "kyber1024".
* g10/call-agent.c (agent_get_keyinfo): Fix warning.
* g10/keygen.c (do_create_from_keygrip): Support Kyber.
(ask_algo): Ditto.
--
To test create a standard key and the use --edit-key and "addkey" with
selection 13 and use the comma delimited keygrips.
GnuPG-bug-id: 7014
* g10/keyid.c (keygrip_from_pk): Add arg get_second to support dual
algos. Implement for Kyber.
(hexkeygrip_from_pk): Extend for dual algos.
* g10/call-agent.c (agent_keytotpm): Bail out for dual algos.
(agent_keytocard): Ditto.
(agent_probe_secret_key): Handle dual algos.
(agent_probe_any_secret_key): Ditto.
(agent_get_keyinfo): Allow for dual algos but take only the first key.
* g10/export.c (do_export_one_keyblock): Bail out for dual algos.
--
This also adds some fixmes which we eventually need to address.
GnuPG-bug-id: 6815
* 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.
--
This could be done by using "set your own capabilities" for an RSA
key. In fact it was always set in this case.
GnuPG-bug-id: 7072
* common/openpgpdefs.h (PUBKEY_ALGO_KY768_25519): Remove.
(PUBKEY_ALGO_KY1024_448): Remove.
(PUBKEY_ALGO_KYBER): New. Use them everywhere instead of the removed.
* g10/build-packet.c (gpg_mpi_write_nohdr): Rename to
(gpg_mpi_write_opaque_nohdr): this. Change callers.
(gpg_mpi_write_opaque_32): New.
(do_key): Support Kyber keys using the revised format.
* g10/gpg.h (MAX_EXTERN_KEYPARM_BITS): New.
* g10/parse-packet.c (read_octet_string): Add arg nbytes so support
reading with a length prefix. Adjust callers.
(parse_key): Parse Kyber public keys.
* g10/misc.c (pubkey_get_npkey): Support Kyber.
(pubkey_get_nskey): Ditto.
* g10/keyid.c (pubkey_string): Support dual algorithms.
(do_hash_public_key): Support Kyber.
(nbits_from_pk): Ditto.
(keygrip_from_pk): Return the Kyber part for the ECC+Kyber dual algo.
* g10/keygen.c (struct common_gen_cb_parm_s): Add genkey_result2.
Note that this callback is not yet used.
(ecckey_from_sexp): Add optional arg sexp2 and use it for Kyber.
Change callers.
(ecckey_from_sexp): Do not leak LIST in case of an error.
(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.
