matter where the user puts the = sign.
* options.skel: Comment out the first three lines in case someone manually
copies the skel file to their homedir.
* sign.c (clearsign_file): Only use pgp2mode with v3 keys and MD5. This
matches what we do when decoding such messages and prevents creating a
message (v3+RIPEMD/160) that we can't verify.
* sig-check.c (signature_check2): Use G10ERR_GENERAL as the error for
signature digest conflict. BAD_SIGN implies that a signature was checked
and we may try and print out a user ID for a key that doesn't exist.
keydb.h, keyid.c (namehash_from_uid): New function to rmd160-hash the
contents of a user ID packet and cache it in the uid object.
* keylist.c (list_keyblock_colon): Use namehash in field 8 of uids. Show
dates for creation (selfsig date), and expiration in fields 6 and 7.
* trustdb.c (get_validity, get_validity_counts, update_validity): Use new
namehash function rather than hashing it locally.
Simplify by returning a ? for error directly.
* keyedit.c (show_key_with_all_names): Use get_validity_string and
get_ownertrust_string to show full word versions of trust (i.e. "full"
instead of 'f').

as get_ownertrust_info, and get_validity_info, except returns a full
string.
* trustdb.c (get_ownertrust_with_min): New. Same as 'get_ownertrust' but
takes the min_ownertrust value into account.
* trustdb.h, trustdb.c (trust_letter): Make static. (get_ownertrust_info,
get_validity_info): Don't mask the trust level twice.
* trustdb.h, gpgv.c, trustdb.c (get_validity, get_validity_info),
keylist.c (list_keyblock_colon), keyedit.c (show_key_with_all_names_colon,
menu_revuid): Pass a user ID in rather than a namehash, so we only have to
do the hashing in one place.

(release_public_key_parts): Remove unused namehash element for public
keys.
trustdb.c (update_validity): Store temporary full & marginal counts in the
trustdb. (clear_validity, get_validity_counts): Return and clear temp
counts. (store_validation_status): Keep track of which keyids have been

(validate_keys): Only use unused keys for each new round.
(reset_unconnected_keys): Rename to reset_trust_records, and only skip
specifically excluded records.

* keyring.c (keyring_search): skipfnc didn't work properly with non-keyid
searches. Noted by Stefan Bellon.

continue then.
* openfile.c (copy_options_file): Print a warning if the skeleton
file has active options.
(check_key_signature2): Pass the ultimately trusted pk directly to
check_key_signature2 to avoid going through the key selection mechanism.
This prevents a deadly embrace when two keys without selfsigs each sign
the other.
there are no keys to refresh or if there is no keyserver set.
* getkey.c (merge_selfsigs_main): Any valid user ID should make a key
valid, not just the last one. This also fixes Debian bug #174276.

* getkey.c (get_pubkey_byname, get_seckey_byname2, get_seckey_bynames),
keyedit.c (keyedit_menu, menu_addrevoker): Include disabled keys in these
functions.

(import_one): Use it here.
Use merge_keys_and_selfsig in the interactive mode to avoid
wrong key information.

* trustdb.h, trustdb.c (trustdb_pending_check): New function to
check if the trustdb needs a check.
* import.c (import_keys_internal): Used here so we don't rebuild
the trustdb if it is still clean.
(import_one, chk_self_sigs): Only mark trustdb dirty if the key
that is being imported has any sigs other than self-sigs.
Suggested by Adrian von Bidder.
* options.skel: Include the required '=' sign in the sample
'group' option. Noted by Stefan Bellon.
* import.c (chk_self_sigs): Don't try and check a subkey as if it
was a signature.
RECTYPE_TRUST records a bit.
* g10.c (main): Comment out --list-trust-path until it can be implemented.
* import.c (import_one): Warn when importing an Elgamal primary that this
may take some time (to verify self-sigs). (chk_self_sigs): Try and cache
all self-sigs so the keyblock is written to the keyring with a good rich
cache.
* keygen.c (ask_algo): Make the Elgamal sign+encrypt warning stronger, and
remove the RSA sign+encrypt warning.
* options.h (opt): Added mangle-dos-filenames.

filename only when this option is set; this is the default.
Minimal isn't always best.

modification of the original signature time. Make sure that this doesn't
cause a time warp.
* keygen.c (keygen_add_key_expire): Properly handle a key expiration date
in the past (use a duration of 0).
* keyedit.c (menu_expire): Use update_keysig_packet so any sig subpackets
are maintained during the update.

function to update version record values during a trustdb check or update.
(tdbio_dump_record): Show trust model in dump.
* trustdb.c (validate_keys): Call tdbio_update_version_record on success
so that the correct options are stored in the trustdb.
* options.h: rearrange trust models so that CLASSIC is 0 and OPENPGP is 1.
pkclist.c (algo_available), revoke.c (gen_revoke): Add --pgp8 mode. This
is basically identical to --pgp7 in all ways except that signing subkeys,
v4 data sigs (including expiration), and SK comments are allowed.

encode_crypt): Call default_cipher_algo and default_compress_algo to get
algorithms.
* g10.c (main): Allow pref selection for compress algo with --openpgp.
--personal-digest-preferences is, then use the first hash algorithm in the
personal list. If the signing algorithm is DSA, then use the first
160-bit hash algorithm in the personal list. If --pgp2 is set and it's a

"uncompressed".
partial length encoding. This is required because OpenPGP allows only for
32 bit length fields. From Werner on stable branch.

made extern. (get_pubkey_byfprint_fast): New. From Werner on stable
branch.
* keydb.h, import.c (import_one): Use get_pubkey_fast instead of
get_pubkey. We don't need a merged key and actually this might lead to
recursions. (revocation_present): Likewise for search by fingerprint.
From Werner on stable branch.
* g10.c (main): Try to create the trustdb even for non-colon-mode list-key

* passphrase.c (agent_send_all_options): Fix compile warning.
* keylist.c (list_keyblock_colon): Validity for subkeys should match that
of the primary key, and not that of the last user ID.
* getkey.c (merge_selfsigs): Revoked/expired/invalid primary keys carry
these facts onto all their subkeys, but only after the subkey has a chance
to be marked valid. This is to fix an incorrect "invalid public key"
error verifying a signature made by a revoked signing subkey, with a valid
unrevoked primary key.

keyring. (keydb_locate_writable): Prefer the default keyring if possible.
* g10.c (main): Add --default-keyring option.

trustdb.
passphrase against all secret keys rather than trying all secret keys in
turn. Don't if --try-all-secrets or --status-fd is enabled.
* passphrase.c (passphrase_to_dek): Mode 1 means do a regular passphrase
query, but don't prompt with the key info.
* seckey-cert.c (do_check, check_secret_key): A negative ask count means
to enable passphrase mode 1.

"always" which is the same as the current option --always-trust (which
still works). Default is "openpgp".

trust sigs.
* gpgv.c (main), mainproc.c (check_sig_and_print), pkclist.c (do_we_trust,
do_we_trust_pre, check_signatures_trust): Use new --trust-model option in

* main.h, keygen.c (keygen_get_std_prefs), keyedit.c (keyedit_menu):
Return and use a fake uid packet rather than a string since we already
have a nice parser/printer in keyedit.c:show_prefs.

regexp subpackets.
* trustdb.h, trustdb.c (clear_ownertrusts), delkey.c (do_delete_key),
import.c (import_one): Rename clear_ownertrust to clear_ownertrusts and
have it clear the min_ownertrust value as well.
* keylist.c (list_keyblock_print): Indent uid to match pub and sig.

* main.h: Prototypes for the new functions.
* delkey.c (do_delete_key): Use it here.
* revoke.c (gen_desig_revoke): Ditto.
show_prompt, keyserver_search_prompt, keyserver_spawn): Go to version 1 of
the keyserver protocol. This is a better design, similar to
--with-colons, that allows for keys with multiple user IDs rather than
using multiple keys. It also matches the machine readable pksd format.
Also use a prettier --search-keys listing format that can fill different
size windows (currently set at 24 lines).

* sig-check.c (signature_check2): Use new is_primary flag to check rather
than comparing main_keyid with keyid as this still works in the case of a
not fully filled in pk.

* status.c, status.h (STATUS_IMPORT_OK): New.
* import.c (import_one,import_secret_one): Print new status.
* options.skel: The PGP LDAP keyserver is back. Use MIT keyserver as a
sample rather than cryptnet as cryptnet does not support searching yet.
* keyedit.c (show_key_with_all_names): Fix error message (preferences are
userid/selfsig and not key specific).
* encode.c (encode_simple,encode_crypt): Use new style CTB for
compressssed packets when using MDC. We need to do this so that
concatenated messages are properly decrypted. Old style
compression assumes that it is the last packet; given that we
can't determine the length in advance, the uncompressor does not
know where to start. Actually we should use the new CTB always
but this would break PGP 2 compatibility.
* parse-packet.c (parse): Special treatment for new style CTB
compressed packets.
* build-packet.c (do_mdc): Removed. Was not used.
(do_encrypted_mdc): Count the version number and the MDC packet.

revocation keys.
* pkclist.c (do_edit_ownertrust): Comment out the option for showing trust
paths until it can be implemented.

the chosen ciphertext attack.
* pkclist.c (select_algo_from_prefs): Fix requested algorithm bug so the
request succeeds even if the requested algorithm is not the first found.
* cipher.c (write_header), encode.c (use_mdc, encode_simple, encode_crypt,
encrypt_filter), g10.c (main): Be more eager to use a MDC. We use a MDC

will not do the right thing.
* main.h, tdbio.c (tdbio_set_dbname), misc.c (removed check_permissions),
keydb.c (keydb_add_resource), g10.c (main, check_permissions): Significant
reworking of the permission check mechanism. The new behavior is to check
everything in the homedir by checking the homedir itself. If the user
wants to put (possibly shared) keyrings outside the homedir, they are not
checked. The options file and any extension files are checked wherever
they are, as well as their enclosing directories. This is Debian bug
147760.

translations.
* encode.c (write_pubkey_enc_from_list): Warn when using --throw-keyid

"repair-hkp-subkey-bug", which repairs as much as possible the HKP
mangling multiple subkeys bug. It is on by default for keyserver
receives, and off by default for regular --import.
* main.h, import.c (import, import_one, delete_inv_parts), hkp.c
(hkp_ask_import), keyserver.c (keyserver_spawn): Use keyserver import
options when doing keyserver receives.
keyserver.c (keyserver_spawn): If the user does not use "exec-path",
completely replace $PATH with GNUPG_LIBEXECDIR before calling the
keyserver helper. If the user does use "exec-path", append
GNUPG_LIBEXECDIR after the specified path.
delete_inv_parts), keyserver.c (parse_keyserver_options): add new
--import-options option. The only current flag is "allow-local-sigs".
* g10.c (main): Don't disable MDC in pgp7 mode.

revoker flag.
* revoke.c (gen_desig_revoke): When generating a designated revocation,
include the direct key sig that contains the designated revoker subpacket.
This allows sensitive designated revocation subpackets to be exported.
Also indicate which revokers are sensitive in the first place.
designated revoker means "sensitive", not "local". It's exportable under
the right circumstances.
* main.h, options.h, export.c (do_export_stream), g10.c (main), hkp.c
(hkp_export), keyserver.c (keyserver_spawn: Add a flag to skip attribute
packets and their signatures while exporting. This is to accomodate
keyservers (pksd again) that choke on attributes. Use keyserver-option
"include-attributes" to control it. This defaults to ON (i.e. don't
skip).
keyserver_work), hkp.c (hkp_ask_import, hkp_export, hkp_search): Use a
much more strict reading of RFC-2396 for the keyserver URIs. Specifically,
don't try and be smart about checking the value of ":port" so long as it
is all digits, and properly handle opaque data (those scheme specific
parts that do not start with "//").

recreate it when needed.
* mainproc.c (check_sig_and_print): Properly disregard expired uids.
Make sure that the first uid listed is a real uid and not an attribute
(attributes should only be listed in the "aka" section). When there are
no valid textual userids, try for an invalid textual userid before using
any attribute uid.
