* 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
* agent/pkdecrypt.c (agent_hybrid_pgp_kem_decrypt): Change the format
of SEXP in the protocol for symmetric cipher algorithm identifier.

* 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: 5888
* 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.
* common/sexputil.c (get_pk_algo_from_key): Increase buffer for use
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
* 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.
* 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.

(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.
GnuPG-bug-id: 6815
* 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*.
* sm/certreqgen-ui.c (gpgsm_gencertreq_tty): Add a prompt for
extensions.
--
An example for an extension would be extKeyUsage for authentication:
2.5.29.37 n 301406082B0601050507030206082B06010505070301
* common/sysutils.c (no_translate_sys2libc_fd) [W32]: New global.

(translate_sys2libc_fd): Make static and cobuild only for Windows.
(translate_sys2libc_fd_int): Use no_translate_sys2libc_fd flag.
* g10/gpg.c, sm/gpgsm.c (oDisableFdTranslation): New const.
(opts): Add option "disable-fd-translation".
(main): Set option.

(parse_gpgconf_ctl): Support keyword "gnupg".
(my_gnupg_dirname): New.
(my_fixed_default_homedir): New.
(gnupg_registry_dir): New.
(standard_homedir): Use my_gnupg_dirname and my_fixed_default_homedir.
(default_homedir): Use gnupg_registry_dir and
my_fixed_default_homedir.
(_gnupg_socketdir_internal): Use my_gnupg_dirname. Increase size of
prefixbuffer.
(gnupg_sysconfdir): Use my_gnupg_dirname.
* tools/gpgconf.c (list_dirs): Use gnupg_registry_dir.
(show_other_registry_entries): Ditto.
--
This will be useful to install versions of GnuPG VS-Desktop and GnuPG
Desktop in addition to a standard GnuPG version. Only basic tests on
Unix done; Windows testing is still outstanding.
GnuPG-bug-id: 7040
* common/homedir.c (gpgconf_ctl): new struct.
(string_is_true): New.
(parse_gpgconf_ctl): New. Based on the former code in unix_rootdir.
(check_portable_app): Use parse_gpgconf_ctl and the new struct.
(unix_rootdir): Ditto.
--
This is a unification of the gpgconf.ctl mechanism. For backward
compatibility we need to keep the empty (or actually only comments)
method as used formerly under Windows. Iff one really wants a
portable application the new portable keyword should be used, though.
Noet that the Windows portable stuff has not been tested for quite
some time.
* g10/mainproc.c (proc_encrypted): Force a decryption failure if any
error has been seen.
* g10/decrypt-data.c (aead_checktag): Issue an ERROR line.
--
GnuPG-bug-id: 7042
Note that gpg in any case returns a failure exit code but due to
double forking GPGME would not see it.
* g10/options.h (LIST_STORE_X509_NOTATIONS): New.
* g10/gpg.c (parse_list_options): Add "store-x509-notations".
* g10/keylist.c (print_x509_notations): Add arg PK and code to write a
file.
(list_signature_print): Add arg lastpk and handle new option.
(list_keyblock_print): Track last key or subkey and pass to
list_signature_print.
* scd/ccid-driver.h (VENDOR_ACR, ACR_122U): New.
* scd/ccid-driver.c (ccid_open_usb_reader): Do not call
libsub_set_interface_alt_setting for this reader.

* tools/gpg-wks-client.c (mirror_one_key): Test for no domain
specified.
--
The code did not really work if no domain was given. It worked but
filtered out all keys so that no key was actually exported.
