GnuPG-bug-id: 7097
Signed-off-by: NIIBE Yutaka <gniibe@fsij.org>
* 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
* configure.ac (NEED_LIBGCRYPT_VERSION): Set to 1.11.0
* agent/pkdecrypt.c (struct ecc_params): Move constants to the top.
--
It does not make anymore sense to allow building with older Libgcrypt
versions. After all PQ key support is a major feature and for this we
need Libgcrypt.
* 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.
* 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/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
* 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*.
* 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.
* g13/g13.c (oNoMount): New.
(opts): Add --no-mount.
(main): Implement this.
* g13/g13-common.h (opt): Add field no_mount.
* common/status.h (STATUS_PLAINDEV): New.
* g13/sh-cmd.c (has_option): Uncomment.
(cmd_mount): Add option --no-mount and pass down.
* g13/sh-dmcrypt.c (sh_dmcrypt_mount_container): Add arg nomount and
emit PLAINDEV status line.
(sh_dmcrypt_umount_container): Rund findmnt before umount.
--
This option can be used to decrypt a device but not to mount it. For
example to run fsck first. A command or option to run fsck before a
mount will eventually be added.
The use of findmnt is needed so that we can easily remove a device
which has not been mounted.
* common/homedir.c (copy_dir_with_fixup) [W32]: Fold double
backslashes.
--
This is in general no problem but when we hash or compare the directory
to test whether tit is the standard home directory, we may use a
different socket file and thus a second instance of a daemon.
GnuPG-bug-id: 6833
* scd/app-common.h (CARDTYPE_SCE7): New.
* scd/app.c (strcardtype): Support it.
(atr_to_cardtype): New.
(app_new_register): Try to get the cardtype from atr_to_cardtype.
* scd/app-piv.c (app_select_piv): Tweak for SCE7. Add general method
to construct a S/N from the Card UUID.
--
The test cards I have are rsa2048 with X.509 certificates. I don't
have the entire chain but loading the certificates work. For testing
I created an OpenPGP key from the keys and tested signing and
decryption.
GnuPG-bug-id: 6919
* common/homedir.c (enum wantdir_values): New enums.
(unix_rootdir): Change arg to use the enums. Adjust all callers. Add
support for the socketdir keyword.
(_gnupg_socketdir_internal): Take care of the socketdir keyword in
gpgconf.ctl.
* doc/tools.texi (Files used by gpgconf): Briefly explain the
gpgconf.ctl syntax.
* common/dotlock.h (DOTLOCK_LOCK_BY_PARENT, DOTLOCK_LOCKED): New.
* common/dotlock.c [HAVE_POSIX_SYSTEM]: Include <dirent.h>.
(dotlock_get_process_id, dotlock_detect_tname): New.
(dotlock_create_unix): Handle the case when no_write option is
specified. Not creating the lock file, but detect the the file of
tname.
(dotlock_create) [HAVE_POSIX_SYSTEM]: Add support of
DOTLOCK_LOCK_BY_PARENT and DOTLOCK_LOCKED for dotlock CLI util.
(dotlock_take_unix): Support the case of DOTLOCK_LOCK_BY_PARENT.
--

* common/dotlock.h (enum dotlock_reasons): New.
(DOTLOCK_PREPARE_CREATE): New flag.
* common/dotlock.c (struct dotlock_handle): Add info_cb and
info_cb_value.
(dotlock_create): Support the new flag.
(dotlock_finish_create): New.
(read_lockfile): Silence in case of ENOENT.
(dotlock_set_info_cb): New. Use callback after all error and info
messages.
(dotlock_take_unix, dotlock_take_w32): Allow termination by callback.
* common/name-value.c (struct name_value_container): Add flag
"modified".
(nvc_modified): New.
(nvc_new): Set flag.
(_nvc_add): Set flag.
(nvc_delete): Set flag.
(nvc_set): Set flag unless value did not change.
(nve_set): Add arg PK. Change the caller.
* agent/findkey.c (agent_write_private_key): Update only if modified.
--
This helps software which uses a file system watcher to track changes
to private keys. In particular smartcard triggered changes are a
problem for such software because this may at worst trigger another
smartcard read.
GnuPG-bug-id: 6829
* common/miscellaneous.c (is_openpgp_compressed_packet)
(is_file_compressed): Moved to ...

here.
(cipher_filter_cfb): Call write_status_printf when called with
IOBUFCTRL_INIT.
* g10/encrypt.c (encrypt_simple): Use new is_file_compressed function,
after call of iobuf_push_filter.
(encrypt_crypt): Likewise.
* g10/sign.c (sign_file): Likewise.

* g10/misc.c (pubkey_get_nenc): Add ky768 and ky1024 values.
* g10/parse-packet.c (read_octet_string): New.
(read_size_body): Rename to ...
(read_sized_octet_string): this and change args to update-able PKTLEN.
(parse_pubkeyenc): Split general parsing loop for easier reading.
Implement parser for the Kyber algorithms.
--
Take care: this has not been tested at all, it merely passes the
regression test for the other algos.
Kyber is also known as ML-KEM in FIPS-203.
The list mode is slighly changed: In case of a parsing error no data
is printed - before that already parsed data was printed.

* common/mischelp.c (timegm): Move to ...
* common/gettime.c (timegm): here. On Windows use timegm_u32.
(timegm_u32): New.
(isotime2epoch): Factor code out to ...
(isotime_make_tm): new helper.
(isotime2epoch_u64): New.
(_win32_timegm): Remove duplicated code.
(parse_timestamp): Use of timegm.
(scan_isodatestr): Fallback to isotime2epoch_u64.
--
This mainly helps on 32 bit Windows. For Unix we assume everyone is
using 64 bit or shall wait until the libc hackers finally provide a
time64_t.
