* common/recsel.c (struct recsel_expr_s): Add field lefta. (recsel_parse_expr): Parse it. (recsel_select): Implement selection. -- This flags makes it for example easy to select keys last updated from an ldap server: gpg --list-filter 'select=origin=ks && -^ url =~ ldap' \ -k --with-key-origin

* common/compliance.c (get_assumed_de_vs_compliance): Also consider a registry entry. -- On Windows it is easier to set the registry key than to use an envvar.

This returns 2023 instead of 23 to indicate the non-approval state. GnuPG-bug-id: 6638
2024-10-21common: Fix test for the assumed compliance.Werner Koch1-1/+1
* common/compliance.c (gnupg_status_compliance_flag): Fix test. -- In general the cache is used to query this flag but in this function it is used directly and we need to adjust the test. Thanks to Ingo for reporting this.

2024-10-07Implement GNUPG_ASSUME_COMPLIANCE envvar for testingWerner Koch1-1/+19
* common/compliance.c (assumed_de_vs_compliance): New. (get_compliance_cache): Check envvar and fake compliance. (gnupg_status_compliance_flag): Return 2023 for de-vs if in faked mode. * g10/gpg.c (gpgconf_list): For compliance_de_vs return 23 or 2023. -- The user visible changes are that GNUPG_ASSUME_COMPLIANCE=de-vs gpgconf --list-options gpg \ | awk -F: '$1=="compliance_de_vs" {print $8}' returns 2023 if "compliance de-vs" is found in gpg.conf. If eventually the software is arpproved the returned value will be 23 and not 1 as it was before. Consumers should check whether they see value of true (Kleopatra does this right now) and also check whether the value is > 2000 and in this case print a beta/non-approved warning. The envvar is currently used to assume that the underlying libgcrypt is compliant and approved. This is not yet the case but eventually libgcrypt will announce this itself and from then on the envvar is not anymore required for testing.

(parse_shrouded_key_bag): Create a new context instead of using the former encapsulated mechanism for tlv_expect_octet_string. (parse_bag_data): Ditto. (p12_parse): Ditto. -- GnuPG-bug-id: 7213 Fixing this took way too long; I should have earlier explained the code to a co-hacker to find the problem myself in my code by this.

* 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
2024-04-03gpg: Initial support for generating Kyber subkeys.Werner Koch1-2/+1
* 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
2024-04-03common: Extend openpgp_oid_to_curve to return an abbreviated name.Werner Koch2-14/+39
* 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.
2024-04-03common: Allow building with libgcrypt 1.10 for now.Werner Koch1-0/+4
* 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*.
