* 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 (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.
GnuPG-bug-id: 6815
* 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/openpgp-oid.c (map_gcry_pk_to_openpgp): Map KEM to Kyber.

* g10/keyid.c (keygrip_from_pk): Add arg get_second to support dual
algos. Implement for Kyber.
(hexkeygrip_from_pk): Extend 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/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.

* 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.
GnuPG-bug-id: 6815
* g10/keygen.c (struct common_gen_cb_parm_s): New.
(common_gen): Add args common_gen_cb and common_gen_cb_parm. Adjust
all callers.
(do_generate_keypair): Clarify the code by using a better var name.
--
We may eventually also replace the long arg list with that object.
The immediate reason for this change is the followup commit.
* g10/keygen.c (curve_is_448): New.
(do_create_from_keygrip): Pass arg keygen_flags byref so that it can
be updated. Set v5 flag for X448.
(gen_ecc): Ditto.
(do_create): Change keygen_flags as above. For robustness change
checking for Ed448.
(do_generate_keypair): Change keygen_flags as above
(generate_subkeypair): Ditto.
(gen_card_key): Ditto. Support v5 keys.

--
The problem showed up because in 2.4 we changed the standard ECDH
parameter some years ago. Now when trying to write an ECDH key
created by 2.2 with 2.4 to an openpgp card, scdaemon computes a wrong
fingerprint and thus gpg was not able to find the key again by
fingerprint.
The patch also avoids updating the stored fingerprint in certain
situations.
This fix is somewhat related to

This makes use of a new encryption flag:
The "restricted encryption key" (2nd,0x04) does not take part in any
automatic selection of encryption keys. It is only found on a
subkey signature (type 0x18), one that refers to the key the flag
applies to.
Followup patches will add encryption support and a --quick command.

This option allows to export a secret key in GnuPG's native format.
Thus no re-encryption is required and further the public key parameters
are also authenticated if a protection passphrase has been used.
Note that --import is not yet able to handle this new mode. Although
old version of GnuPG will bail out with "invalid packet" if a mode1003
exported secret key is seen.
* g10/export.c (receive_seckey_from_agent): Add arg r_key.
(do_export_one_keyblock): Pass NULL for new arg.

Due to the meanwhile expired patent on OCB there is no more reason for
using EAX. Thus we forcefully use OCB if the AEAD feature flag is set

The reason for this change is that we don't enforce these constraints
in the --quick-gen-key interface. I added the constraints right in the
beginning of gnupg to make sure that we have a uniform style for
user-ids. However, this is all problematic with non-Latin names
and we prefer to use mail addresses anyway.
* g10/gpg.c (main): Remove note about rfc4880bis.
* g10/keygen.c (keygen_set_std_prefs): Use only OCB in the AEAD

It is more than unlikely that EAX will ever be used in practice and
thus we remove it from the preference list.
* g10/keygen.c (generate_subkeypair): On error, write error and
