* gpg: Fix writing ECDH keys to OpenPGP smartcards.Werner Koch2023-04-211-21/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * agent/command.c (cmd_keytocard): Add new arg for ECDH params. * scd/app-openpgp.c (ecc_writekey): Use provided ECDH params to compute the fingerprint. * g10/call-agent.c (agent_keytocard): Add arg ecdh_param_str. * g10/keyid.c (ecdh_param_str_from_pk): New. * g10/card-util.c (card_store_subkey): Pass ECDH params to writekey. * g10/keygen.c (card_store_key_with_backup): Ditto. * scd/app-openpgp.c (store_fpr): Add arg update. (rsa_read_pubkey, ecc_read_pubkey): Add arg meta_update and avoid writing the fingerprint back to the card if not set. (read_public_key): Also add arg meta_update. (get_public_key): Do not pass it as true here... (do_genkey): ... but here. (rsa_write_key, ecc_writekey): Force string the fingerprint. -- The problem showed up because in 2.4 we changed the standard ECDH parameter some years ago. Now when trying to write an ECDH key created by 2.2 with 2.4 to an openpgp card, scdaemon computes a wrong fingerprint and thus gpg was not able to find the key again by fingerprint. The patch also avoids updating the stored fingerprint in certain situations. This fix is somewhat related to GnuPG-bug-id: 6378
* scd,openpgp: Switch key attributes between RSA and ECC in writekey.Werner Koch2023-03-151-5/+30

(pubkey_algo_string): Ditto. * scd/app-openpgp.c (do_writekey): Switch key attributes -- The scd WRITEKEY command for OpenPGP cards missed proper support to aautomagically switch key attributes based on the new key. We had this only in GENKEY. GnuPG-bug-id: 6378

Add checking for Ed25519 for ECC_FLAG_DJB_TWEAK flag. -- There used to be a possible support of Ed25519 with ECDSA, (instead of EdDSA).
