* g10/sign.c (update_keysig_packet): Honor --cert-digest-algo when
recreating a cert.
This is used by various things in --edit-key like setpref, primary,
etc. Suggested by Christian Aistleitner.
for are >=v4. (write_signature_packets, make_keysig_packet): Only
call it for >=v4 sigs. This allows --force-v3-sigs and
--force-v4-certs to enable or disable notations, policies, and
keyserver URLs. This is bug#800.
Change all callers. (sign_file, clearsign_file,
sign_symencrypt_file): Calculate one timestamp for the whole
transaction. Different timestamps for each step can leak performance
information.
and one being DSA2 and encrypting at the same time, if the recipient
preferences give a hash that can work with the DSA2 key, then allow the
DSA1 key to be promoted rather than giving up and using hash_for().
(build_sig_subpkt_from_sig), getkey.c (fixup_uidnode,
merge_selfsigs_main, merge_selfsigs_subkey), keygen.c
(keygen_add_key_expire): Fix meaning of key expiration and sig
expiration subpackets - zero means "never expire" according to 2440,
not "expire instantly".
to disable.
* pkclist.c (algo_available): If --enable-dsa2 is set, we're allowed to
truncate hashes to fit DSA keys.
* sign.c (match_dsa_hash): New. Return the best match hash for a given q
size. (do_sign, hash_for, sign_file): When signing with a DSA key, if it
has q==160, assume it is an old DSA key and don't allow truncation unless
--enable-dsa2 is also set. q!=160 always allows truncation since they
must be DSA2 keys. (make_keysig_packet): If the user doesn't specify a
--cert-digest-algo, use match_dsa_hash to pick the best hash for key
signatures.
SHA-224.
* sign.c (write_plaintext_packet), encode.c (encode_simple): Factor
common literal packet setup code from here, to...
* main.h, plaintext.c (setup_plaintext_name): Here. New. Make sure the
literal packet filename field is UTF-8 encoded.
* options.h, gpg.c (main): Make sure --set-filename is UTF-8 encoded
and note when filenames are already UTF-8.
than 160 bits as per DSA2. This will allow us to verify and issue DSA2
signatures for some backwards compatibility once we start generating DSA2
keys.
* sign.c (do_sign), sig-check.c (do_check): Change all callers.
* sign.c (do_sign): Enforce the 160-bit check for new signatures here
since encode_md_value can handle non-160-bit digests now. This will need
to come out once the standard for DSA2 is firmed up.
Use it here for the various notation commands.
* packet.h, main.h, keygen.c (keygen_add_notations), build-packet.c
(string_to_notation, sig_to_notation) (free_notation): New "one stop
shopping" functions to handle notations and start removing some code
duplication.
card. If it does, only allow 160-bit hashes, a la DSA. This involves
passing the *sk in, so change all callers. This is correct for today,
given the current 160-bit q in DSA, and the current SHA-1/RIPEMD160
support in the openpgp card. It will almost certainly need changing
down the road.
* app-openpgp.c (do_sign): Give user error if hash algorithm is not
supported by the card.
(sign_file, clearsign_file, sign_symencrypt_file), g10.c (main), keyedit.c
(sign_uids): Use seconds rather than days internally to calculate
expiration. We no longer need the day-based code as we don't generate v3
keys.
--default-cert-expire options. Suggested by Florian Weimer.
* main.h, keygen.c (parse_expire_string, ask_expire_interval): Use
defaults passed in, or "0" to control what default expiration is.
* keyedit.c (sign_uids), sign.c (sign_file, clearsign_file,
sign_symencrypt_file): Call them here, so that default expiration
is used when --ask-xxxxx-expire is off.
Changed all callers.
(ask_passphrase): Add new arg CACHEID and use it in agent mode.
Changed all callers.
(passphrase_clear_cache): New arg CACHEID. Changed all callers.
* cardglue.c (format_cacheid): New.
(pin_cb): Compute a cache ID.
(agent_scd_pksign, agent_scd_pkdecrypt): Use it.
(agent_clear_pin_cache): New.
* card-util.c (change_pin): Clear the PIN cache.
(check_pin_for_key_operation): Ditto.
filename when using --use-embedded-filename with input that has no
filename (clearsigned or message generated from a pipe).
* encode.c (encode_simple, encode_crypt), progress.c (handle_progress),
sign.c (write_plaintext_packet): Fix a few inconsistent calls (NULL
filename means a pipe here, so don't bother to check it twice).
Elgamal signing keys since we no longer support any Elgamal signing keys.
* sign.c (sign_file, clearsign_file): Use "writing to" instead of "writing
to file" to match other strings.
* pkclist.c (check_signatures_trust): Fix typo. Noted by Moray Allan.
This is Debian bug #278708.
* passphrase.c (ask_passphrase, passphrase_to_dek): "password" ->
"passphrase".
* keyedit.c (show_key_with_all_names): Show designated revoker as part of
translatable string.
* exec.c, sign.c: Change "can't open file" to "can't open" and "can't
create file" to "can't create" to be consistent with other strings so we
don't have to translate both.
http.
* openfile.c (overwrite_filep, make_outfile_name, open_outfile)
(open_sigfile): Use iobuf_is_pipe_filename to check for pipes so
that special filesnames are taken into account. This is bug 327.
* tdbdump.c (import_ownertrust): Ditto.
* sign.c (write_plaintext_packet): Ditto.
* progress.c (handle_progress): Ditto.
* plaintext.c (handle_plaintext): Ditto.
* encode.c (encode_simple, encode_crypt): Ditto.
* iobuf.c (iobuf_is_pipe_filename): New.
* fileutil.c (is_file_compressed): Use it here.
opt.s2k_digest_algo. This helps fix a problem with PGP 2.x encrypted
symmetric messages. Change all callers (encode.c, g10.c, keyedit.c,
keygen.c, passphrase.c, sign.c).
* armor.c, cardglue.c, getkey.c, import.c, keygen.c: Be consistent in some
more quoted strings. Always use 'user ID', not 'user id', "quotes" for
user IDs, etc.
* g10.c (main): New alias --throw-keyid for --throw-keyids, so that it
continues to work in old configuration files. Noted by Jens Adam.
* pkclist.c (algo_available): --pgp8 now allows blowfish, zlib, and bzip2.
* status.c (do_get_from_fd): Flush stdout if status isn't flushing it for
us. This guarantees that any menus that were displayed before the prompt
don't get stuck in a buffer. Noted by Peter Palfrader. This is Debian
bug #254072.
* sign.c (update_keysig_packet): Revert change of 2004-05-18. It is not
appropriate to strip policy and notations when remaking a sig. That
should only happen when specifically requested by the user.
expired user IDs. Also, once we've established that a given uid cannot or
will not be signed, don't continue to ask about each sig.
* mainproc.c (proc_symkey_enc), seckey-cert.c (do_check): Check the S2K
hash algorithm before we try to generate a passphrase using it. This
prevents hitting BUG() when generating a passphrase using a hash that we
don't have.
* sign.c (sign_symencrypt_file): Allow using --force-mdc in --sign
--symmetric messages.
generate_subkeypair): New is_subkey argument to set whether a generated
key is a subkey. Do not overload the ret_sk. This is some early cleanup
to do backsigs for signing subkeys.
* keygen.c (write_keybinding, do_generate_keypair, generate_subkeypair):
Keep track of the unprotected subkey secret key so we can make a backsig
with it.
* keygen.c (make_backsig): New function to add a backsig to a binding sig
of signing subkeys. Currently disabled. (write_keybinding): Call it here,
for signing subkeys only.
* sign.c (make_keysig_packet): Allow generating 0x19 signatures (same as
0x18 or 0x28, but used for backsigs).
* packet.h, build-packet.c (build_sig_subpkt): Add new SIGSUBPKT_SIGNATURE
type for embedded signatures.
encode_md_value), sig-check.c (do_check), sign.c (do_sign): Remove
--emulate-md-encode-bug as it only applied to Elgamal signatures, which
are going away.
* main.h, encode.c (setup_symkey): New. Prompt for a passphrase and
create a DEK for symmetric encryption. (write_symkey_enc): New. Write out
symmetrically encrypted session keys. (encode_crypt, encrypt_filter): Use
them here here when creating a message that can be decrypted with a
passphrase or a pk.
* sign.c (sign_file): Call setup_symkey if we are doing a --symmetric
--sign --encrypt.
check_compress_algo): Add bzip2.
* compress.c (compress_filter): Make static to help force the use of
push_compress_filter. Remove default algorithm setting since that is done
in push_compress_filter now.
* main.h: Use named algorithm.
* filter.h, compress.c (push_compress_filter, push_compress_filter2): New.
Figure out which is the appropriate compression filter to use, and push it
into place.
* compress.c (handle_compressed), encode.c (encode_simple, encode_crypt),
sign.c (sign_file, sign_symencrypt_file), import.c (read_block), export.c
(do_export): Use push_compress_filter instead of pushing the compression
filter ourselves.
* compress-bz2.c: New. Bzlib versions of the compression filter routines.
* Makefile.am: Include compress-bz2.c if bz2lib is available.
