This patch solves two purposes:
- We write a note that the ADSK key was used for decryption

"oops: public key not found for preference check\n"
due to ADSK keys. The error is mostly harmless but lets gpg return

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.

applies to.

This patch avoid the printing of often hundreds of "Invalid digest

the behaviour.
We now also print "[self-signature]" with --check-sigs or --list-sigs

It might be useful to distribute revocations of old keys along with
new keys. This is in particicualrr useful for WKD stored keys. This
patch allows to put unrelated standalone revocations into a key. For
example they can simply appended to a keyblock. Right now it is a bit

need to have an exact match - this is in particular important for
smartcard which check that the hash matches the curves.

For the compatibility of existing implementation, we keep the format

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.

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.

This code as a lot of rough edges, in particular it relies on a well

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.
We should also see whether we can depend nPth initialization on the
--use-keyboxd option to avoid any problems with nPth.

When importing an invalid secret key ring for example without key

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.

* g10/keydb.h (IS_BACK_SIG): New.
* g10/sig-check.c: Re-indent and use macros.
--
This makes the code easier to understand.

* g10/pkclist.c (select_aead_from_pklist): Return the AEAD_algo.
* g10/encrypt.c (use_aead): Return the AEAD algo.
(encrypt_simple): Adjust for this change.
(encrypt_crypt): Ditto.
(encrypt_filter): Ditto.
* g10/sign.c (sign_symencrypt_file): Ditto.
* g10/misc.c (MY_GCRY_CIPHER_MODE_EAX): New.
(openpgp_aead_algo_info): New.
* g10/cipher-aead.c (MY_GCRY_CIPHER_MODE_EAX): Remove.
(write_header): Use new fucntion.
* g10/decrypt-data.c (MY_GCRY_CIPHER_MODE_EAX): Remove.
(decrypt_data): Use new function. Also allow for chunkbytes other
than 10.
--
Note that other chunk bytes than 10 and in particular 0 (64 byte
chunks) have not yet been tested.

* g10/dek.h (DEK): Turn fields use_mdc, algo_printed and symmetric
into single bit vars. Make sure they are always set to 1 or 0.
(DEK): New field use_aead.
* g10/options.h (struct opt): New field force_aead.
* g10/pkclist.c (select_aead_from_pklist): New.
* g10/gpg.c (oForceAEAD): New const.
(opts): New options "--force-aead".
(main): Set new option.
* g10/encrypt.c (use_aead): New.
(encrypt_simple): Implement new flags DEK.use_aead.
(encrypt_crypt): Ditto.
(encrypt_filter): Ditto.
* g10/sign.c (sign_symencrypt_file): Ditto.
--
This patch should be enough to detect whether AEAD can be used.
Not tested.

* g10/keydb.c (keydb_handle): New field 'keep_lock'.
(keydb_release): Clear that flag.
(keydb_lock): New function.
(unlock_all): Skip if KEEP_LOCK is set.
* g10/getkey.c (get_keyblock_byfprint_fast): Call keep_lock if
requested.
--
That change is straightforward. It helps to avoid the race condition
that another gpg process inserts a key while the first process is
between the search and the insert.
A similar change is due for gpgsm.
Note that the key edit operations may still suffer from a race.
GnuPG-bug-id: 3446
* g10/getkey.c (get_pubkey_byfprint_fast): Factor most code out to ...
(get_keyblock_byfprint_fast): .. new function.
* g10/import.c (revocation_present): s/int rc/gpg_error_t err/.
(import_one): Use get_keyblock_byfprint_fast to get the keyblock and a
handle. Remove the now surplus keyblock fetch in the merge branch.
