* gpg: Make Kyber creation more flexible.wk/kyber-testWerner Koch2024-04-095-11/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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: Changes to the new KEM code in pkdecrypt.cWerner Koch2024-04-091-22/+35
| | | | | | | | | | * 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/.
* gpg: Some support to allow Kyber decryption.Werner Koch2024-04-097-15/+67
| | | | | | | | | | | | | | | | | | * g10/call-agent.c (agent_pkdecrypt): Support dual keygrips and switch to KEM mode. * g10/ecdh.c (pk_ecdh_decrypt): Add an extra length check. * g10/keyid.c (do_hash_public_key): Fix Kyber fingerprint computation. * g10/mainproc.c (release_list): Free all 4 data elements. (proc_pubkey_enc): Copy all 4 data elements. * g10/misc.c (openpgp_pk_test_algo2): Map Kyber to KEM. * g10/parse-packet.c (parse_pubkeyenc): Fix Kyber parser. * g10/pubkey-enc.c (get_session_key): Allow Kyber. (get_it): Support Kyber. -- GnuPG-bug-id: 6815

* kbx: Fix keyid search for mixed v4/v5 case.Werner Koch2024-04-081-28/+25
| | | | | | | | | | | | * 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: 01329da8a778d3b0d121c83bfb61d99a39cccac4 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
* gpg: Allow to create a Kyber key from keygrips.Werner Koch2024-04-056-13/+97

(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

* gpg: Initial support for generating Kyber subkeys.Werner Koch2024-04-039-110/+461
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

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.

(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.

(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

(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.
