runtime as it properly handles algorithms disabled at build or run time.
* getkey.c (merge_selfsigs_main): Properly handle expired user IDs when
the expired self-sig is not the only self-sig.
* misc.c (compress_algo_to_string): Return NULL on failure like all of the
other xxxx_algo_to_string() functions.
* mainproc.c (list_node): Minor spacing tweak to match --list-keys output.
* keylist.c (list_keyblock_print), mainproc.c (list_node): Mark revoked
subkeys as revoked. Requested by Matthew Wilcox. Revoked overrides
expiration when both apply.
* keyedit.c (show_prefs): Use compress algo constants.
(show_basic_key_info): Make revoked and expired tags translatable.
* g10.c (rm_group): Properly ungroup from a list of groups.
group. (add_group): When adding a group with the same name as an already
existing group, merge the two groups. (list_config): Show an error message
when listing a config item that doesn't exist. (main): Replace -z0 trick
for no compression.
* packet.h, keyedit.c (show_key_with_all_names_colon), keylist.c
(list_keyblock_colon), mainproc.c (list_node, proc_tree): Minor cleanup to
remove local_id, which is no longer used.
PK_UID_CACHE_SIZE (set in ./configure).
* getkey.c (get_pubkey): When reading key data into the cache, properly
handle keys that are partially (pk, no UIDs) cached already. This is
Debian bug #176425 and #229549.
* compress.c (init_compress, push_compress_filter2): Do the right thing
(i.e. nothing) with compress algo 0.
* main.h, decrypt.c (decrypt_messages): Accept filenames to decrypt on
stdin. This is bug #253.
* options.h, g10.c (set_screen_dimensions): New function to look at
COLUMNS and LINES.
* keyserver.c (parse_keyrec, keyserver_search_prompt), keyedit.c
(print_and_check_one_sig): Use new screen dimension variables.
Currently requires --with-colons. (collapse_args): New function to turn
argc/argv into a single string. (main): Use it here to pass list_config()
more than one argument as a single string. (print_algo_numbers): Helper to
print algorithm number for --list-config "pubkey", "cipher",
"hash"/"digest", and "compress" config options.
keyring.c (keyring_rebuild_cache): Add "noisy" flag so cache rebuilds can
remain noisy when called for itself, and quiet when called as part of the
trustdb rebuild.
* trustdb.c (validate_keys): Rebuild the sig caches before building the
trustdb. Note that this is going to require some architectual
re-thinking, as it is agonizingly slow.
* keyring.c (keyring_rebuild_cache): Clear sig cache for any signatures
that we can no longer process (say, if the user removed support for a
necessary pubkey or digest algorithm).
* sig-check.c (check_revocation_keys): Comments.
* getkey.c (merge_selfsigs_main): Don't bother to check designated revoker
sigs if the key is already revoked.
* packet.h, getkey.c (merge_selfsigs_main): New "maybe_revoked" flag on
PKs. It is set when there is a revocation signature from a valid
revocation key, but the revocation key is not present to verify the
signature.
* pkclist.c (check_signatures_trust): Use it here to give a warning when
showing key trust.
* compress-bz2.c: Include stdio.h. Solaris 9 has a very old bzip2 library
and we can at least guarantee that it won't fail because of the lack of
stdio.h.
* tdbio.c: Fixed format string bugs related to the use of DB_NAME.
Reported by Florian Weimer.
parse_keyserver_uri): honor-http-proxy is no longer an option since we can
do the same thing with http-proxy with no arguments. Also remove
broken-http-proxy since it can be better handled in the HTTP helper.
(parse_keyserver_options): Use them here to allow arguments to
keyserver-options. Since none of our options need arguments yet, just
pass them through whole to the keyserver helper.
the messages about which option didn't match or matched ambiguously.
Change all callers (g10.c, keyserver.c).
* main.h, import.c (import_options), export.c (export_options): Pass the
noisy flag through.
here... (signature_check2): ... to here. (check_key_signature2): ... and
here. This is a minor optimization to avoid fetching a key (which can be
expensive, especially if it is not self-signed, and there are many key
signatures on it which need to be checked for ultimate trust) if the
signature would have failed anyway because of algorithm or hash problems.
* keydb.h, keyid.c (hash_public_key, do_fingerprint_md): ... and make a
new one here that shares code with the fingerprint calculations. This
removes some duplicated functionality, and is also around 14% faster.
(Every bit helps).
* import.c (import_one): No longer need the Elgamal import warning.
* getkey.c (get_pubkey_fast): This one is sort of obscure. get_pubkey_fast
returns the primary key when requesting a subkey, so if a user has a key
signed by a subkey (we don't do this, but used to), AND that key is not
self-signed, AND the algorithm of the subkey in question is not present in
GnuPG, AND the algorithm of the primary key that owns the subkey in
question is present in GnuPG, then we will try and verify the subkey
signature using the primary key algorithm and hit a BUG(). The fix is to
not return a hit if the keyid is not the primary. All other users of
get_pubkey_fast already expect a primary only.
don't know the structure of by using the opaque MPI.
(do_fingerprint_md_sk): We cannot calculate the fingerprint from a secret
key unless we know the structure (since we can't leave off the secret key
parts), so fail early..... (keyid_from_sk, fingerprint_from_sk): .... and
return all zeroes.
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.
--override-session-key on --symmetric messages (new-style or old-style).
(proc_pubkey_enc): Move code to show session key from here to
proc_encrypted() so it can work with any type of message. Suggested by
Michael Young.
any ultimately trusted keys. This ensures that if we lose all our
ultimately trusted keys, we don't leave behind the old validity
calculations. Noted by Peter Palfrader.
* revoke.c (gen_desig_revoke): Specify in the comment when a designated
revocation is generated.
* getkey.c (merge_selfsigs_main, merge_selfsigs_subkey,
get_seckey_byname2): Remove Elgamal check since we are removing type 20
keys altogether.
* misc.c (compress_algo_to_string): Translate "Uncompressed". Requested by
Tommi Vainikainen. (string_to_compress_algo): Include multi-string for
"uncompressed|none".
"external" trust model, where the user can provide a pregenerated trustdb.
* keyedit.c (keyedit_menu): Do not allow editing ownertrust with an
external trust model trustdb.
* 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.
--quiet is set. Suggested by Duncan Harris. Also don't fail with BUG()
when processing a --symmetric message with a cipher we don't have.
* g10.c: Alias --personal-xxx-prefs to --personal-xxx-preferences.
list of ultimately trusted keys.
* keygen.c (do_generate_keypair): Use it here so that the ultimate
ownertrust happens before the trustdb (might be) rebuilt. Also fix an
error where the newly generated pk is thought to be a subkey by the
trustdb.
* g10.c (main): Fix --export-all do actually do something different than
--export.
* pkclist.c (build_pk_list): Show all recipients rather than showing each
recipient as they are added.
* mainproc.c (proc_symkey_enc, proc_encrypted): Keep a count of the number
of passphrases that can decrypt a symmetric or mixed symmetric/pk message
and include it in the list of keys shown to the user.
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.
* keylist.c (list_keyblock_print): Denote secrets keys stored on a
card with an '>'. Print the '#' also for subkeys.
(list_keyblock_colon): Introduce new field 15 for sec/ssb to print
the serial number.
message that can be decrypted via a passphrase or public key system.
* main.h, encode.c (encode_seskey): Allow passing in an already-created
session key dek. (encode_simple): Use the actual symmetric cipher when
encrypting a session key for a symmetric message. (encode_crypt): Add a
flag to trigger a hybrid mode that can be decrypted via a passphrase or a
pk. Change all callers.
* mainproc.c (symkey_decrypt_sesskey): There is no way to tell the
difference here between a bad passphrase and a cipher algorithm that we
don't have, so use a error message that makes that clear. Use the actual
list of ciphers when checking whether a cipher is invalid. Return error
if the decrypted cipher algorithm is invalid. (proc_symkey_enc): In a
mixed passphrase/pk message, if a valid dek already exists from decrypting
via pk, do not try to process the passphrase. (proc_symkey_enc): Indicate
when we're decrypting a session key as opposed to decrypting data. If a
passphrase is invalid, discard the dek so we'll keep trying.
