* 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
* agent/pkdecrypt.c (agent_hybrid_pgp_kem_decrypt): Replace fixed-info
by an s-exp parameter. Do not expect the algo and extra length octet.
--
This code needs more work, for example extracting the curve from the
s-expression and mapping it to a KEM algo. It might even be better
top move parts of the code to common/.
* g10/armor.c (radix64_read): Detect the end of armor when
there is no CRC24 checksum.

* kbx/keybox-search.c (blob_cmp_fpr_part): Reworked.
(has_short_kid, has_long_kid): Simplify.
--
The old code was too complicated and did not cope correctly a blob
having a mix of v5 and v4 keys.
Fixes-commit: 01329da8a7
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.
(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.
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.
(disable_translate_sys2libc_fd): New.
(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.
--
GnuPG-bug-id: 7060
* common/homedir.c (gpgconf_ctl): Add field "gnupg".
(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.

Fixes-commit: 1ddd69935d
in the not yet released master branch.
* 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.
* g10/trustdb.c: Move a function and some definitions around.
(user_utk_list): Rename to trusted_key_list. Change all users.
(any_trusted_key_seen): New.
(tdb_register_trusted_key): Set it here. Handle the new value "none".
(verify_own_keys): Do not delete a trusted key from the trustdb if a
trusted-key option was not used.
--
GnuPG-bug-id: 7025
* tools/gpg-wks-client.c (oRealClean): New.
(opts): Add "realclean".
(parse_arguments): Implement.
(main): Take a copy of the module name to fix bad assignment from a
former patch.
* tools/gpg-wks-server.c (main): Ditto.
* tools/gpg-wks.h (opt): Add field realclean.
* tools/wks-util.c (wks_get_key): Call gpg with export-realclean
depending on the new option.
--
The default for gpg-wks-client is to install keys with all valid key
signatures. The new option will eventually allow to install the keys
only with key signatures done by trusted-keys. Also the export-option
is in gpg, it requires one more gpg patch to make it actually work.
* g10/options.h (EXPORT_REALCLEAN): New. Also re-assign other values
to keep them more in sync with the corresponding import values.
* g10/export.c (parse_export_options): Add "export-realclean".
(do_export_stream): Call clean_all_uids directly with the options
arg.
* g10/import.c (import_one_real): Change for direct use of options in
clean_all_uids.
* g10/key-clean.c (is_trusted_key_sig): New. Stub for now.
(clean_sigs_from_uid): Re-purpose self_only to a general options arg.
Implement EXPORT_REALCLEAN code path.
(clean_one_uid): Re-purpose self_only to a general options arg.
(clean_all_uids): Ditto.
* g10/keyedit.c (keyedit_menu): Use EXPORT_MINIMAL instead of a simple
flag.
(menu_clean): Re-purpose self_only to a general options arg.
* g10/keyid.c (fpr20_from_pk): Factor code out to ....
(fpr20_from_fpr): new. Remove useless case for ARRAY being NULL.
* g10/tdbio.c (tdbio_search_trust_byfpr): Add arg fprlen and use
fpr20_from_fpr if needed.
(tdbio_search_trust_bypk): Pass 20 for the fingerprint length.
--
Note that this code has no function yet. Another patch will follow to
extract the trusted-keys flag from the trustdb.
* g10/compress-bz2.c: Replace all log_fatal by log_error,
write_status_error, and g10_exit.
(do_uncompress): Ditto.
--
This gives gpgme a better way to detect corrupted data in the
compression layer.
GnuPG-bug-id: 6977
* agent/gpg-agent.c (parse_rereadable_options): Use make_filename_try
for opt.pinentry_program. Change definition accordingly.
* g10/gpg.c (main): Use make_filename for agent_program,
dirmngr_program, and keyboxd_program. Change definition accordingly.
* sm/gpgsm.c (main): Ditto.
* tools/gpg-card.c (parse_arguments): Ditto.
* tools/gpg-connect-agent.c (main): Ditto.
* tools/gpg-wks-client.c (parse_arguments): Likewise. Do it also for
option --output.
(process_confirmation_request): Print a note for a successful sent.
--
GnuPG-bug-id: 7017
* agent/command.c (cmd_get_passphrase): Allow use in restricted mode
but ignore the cacheid.
--
The use case is symmetric encryption via the extra-socket. To avoid
that the gpg running on the server has access to the cache we set the
cache id to NULL so that the cache is not used at all.
* g10/build-packet.c (gpg_mpi_write): Take care of the fact that
get_opaque already returns a bit-exact value.
--
Fixes-commit: ab17f7b6c3

* tools/gpg-wks-client.c (wrong_args): Take two args. Change all
callers.
(main): Pass ARGPARSE_FLAG_COMMAND for recent gpgrt version.
--
This requires gpgrt 1.48. Of course "gpg-wks-client --create ..."
continues to work.
