* gpg: Allow passing a keygrip as description to pinentry.Werner Koch2021-12-201-0/+1
| | | | | | | * g10/keydb.h (FORMAT_KEYDESC_KEYGRIP): New. * g10/passphrase.c (gpg_format_keydesc): Add new mode. Signed-off-by: Werner Koch <wk@gnupg.org>
* gpg: Use a more descriptive prompt for symmetric decryption.Werner Koch2021-05-171-6/+6
| | | | | | | | | | | | | | | | | | | | | * g10/keydb.h (GETPASSWORD_FLAG_SYMDECRYPT): New. (passphrase_to_dek_ext): Remove this obsolete prototype. * g10/passphrase.c (passphrase_get): Add arg flags. Use new flag value. (passphrase_to_dek): Add arg flags and pass it on. * g10/mainproc.c (proc_symkey_enc): Use new flag. * sm/decrypt.c (pwri_decrypt): Use "passphrase". -- Signed-off-by: Werner Koch <wk@gnupg.org> (cherry picked from commit 03f83bcda5d1f8d8246bcc1afc603b7f74d0626b) Note that we keep on using the term "passphrase" although "password" would be better. There are however so many occurance of this and given it is a bike shedding topic we fix that in the PO files. Signed-off-by: Werner Koch <wk@gnupg.org>

* gpg: Fix the encrypt+sign hash algo preference selection for ECDSA.Werner Koch2020-11-131-4/+5
| | | | | | | | | | | | | | | | | | | * g10/keydb.h (pref_hint): Change from union to struct and add field 'exact'. Adjust callers. * g10/pkclist.c (algo_available): Take care of the exact hint. * g10/sign.c (sign_file): Rework the hash detection from recipient prefs. -- This fixes a encrypt+sign case like: One recipient key has SHA512 as highest ranked hash preference but the the signing key is a 256 bit curve. Because we don't want to use a truncated hash with ECDSA, we need to have an exact match - this is in particular important for smartcard which check that the hash matches the curves.

* gpg: Fix trustdb for v5key.NIIBE Yutaka2020-08-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | * g10/keydb.h (fpr20_from_pk): New. * g10/keyid.c (fpr20_from_pk): New. * g10/tdbio.c (tdbio_search_trust_byfpr): Use fpr20_from_pk. * g10/trustdb.c (keyid_from_fpr20): New. (verify_own_keys): Use keyid_from_fpr20. (tdb_update_ownertrust): Use fpr20_from_pk. (update_min_ownertrust): Likewise. (update_validity): Likewise. -- For the compatibility of existing implementation, we keep the format of trustdb untouched. The format of trustdb uses 20-byte fingerprint for the trust record entry. To handle both of v4key (with 20-byte fingerprint) and v5 key (with 32-byte fingerprint), we introduce FPR20 fingerprint, internally. For v4key, FPR20 is as same as v4 fingerprint. For v5key, FPR20 is constructed from v5key fingerprint. GnuPG-bug-id: 5000 Signed-off-by: NIIBE Yutaka <gniibe@fsij.org>

(check_sig_and_print): Try the included key block if no key is available. -- This is is the second part to support the new Key Block subpacket. The idea is that after having received a signed mail, it is instantly possible to reply encrypted - without the need for any centralized infrastructure. There is one case where this does not work: A signed mail is received using a specified signer ID (e.g. using gpg --sender option) and the key block with only that user ID is thus imported. The next time a mail is received using the same key but with a different user ID; the signatures checks out using the key imported the last time. However, the new user id is not imported. Now when trying to reply to that last mail, no key will be found. We need to see whether we can update a key in such a case. GnuPG-bug-id: 4856 Signed-off-by: Werner Koch <wk@gnupg.org>

We need to add code to shutdown the datastream reader thread in case of errors and to properly get it up again. We also need to make really sure that both threads run in lockstep so that the datastream thread is only active while we are sending a command to the keyboxd.

Resync secret keyblock. -- When importing an invalid secret key ring for example without key binding signatures or no UIDs, gpg used to let gpg-agent store the secret keys anyway. This is clearly a bug because the diagnostics before claimed that for example the subkeys have been skipped. Importing the secret key parameters then anyway is surprising in particular because a gpg -k does not show the key. After importing the public key the secret keys suddenly showed up. This changes the behaviour of GnuPG-bug-id: 4392 to me more consistent but is not a solution to the actual bug. Caution: The ecc.scm test now fails because two of the sample keys don't have binding signatures. Signed-off-by: Werner Koch <wk@gnupg.org>

Remove special treatment of ring trust packets and initialization of the signature caches. -- This patch introduced the framework to store meta data for keys and user ids in the keyrings/keyboxes. Ring trust packets are implementation defined and have always been used in gpg to cache the signature verification status. Ring trust packets are only exported with the export option "backup" and only imported with the import option "restore". The new code uses a cleaner way to handle the ring trust packets: When the parser reads a ring trust packet and the previously read packet matches the type of that ring trust packet, the information is stored in that previously read packet (signature, user id, or primary key) and the next packet is read immediately. Thus only the parser sees the ring trust packets. Ring trust packets are written by using the new function build_packet_and_meta instead of build_packet. That function writes a ring trust packet when the needed information is available. As a side-effect of this patch the signature status cache works again and "gpg --check-sigs" is thus much faster.
