algorithm which will be used if available.
* encode.c (encode_crypt, encrypt_filter), sign.c (sign_file): Use new
select_algo_from_prefs feature to check if forcing an algorithm would
violate the recipient preferences.
* photoid.c (get_default_photo_command, show_photos): Use different
default viewers on different platforms. Currently we have Win 9x, Win NT
(2k, xp), Mac OSX, RISC OS, and "everybody else". These are #ifdefs as
much as possible to avoid clutter.
* g10.c (strusage, build_list), keyedit.c (show_prefs), main.h, misc.c
(compress_algo_to_string, check_compress_algo), pkclist.c
(algo_available), keygen.c (keygen_set_std_prefs): New algo_to_string and
check functions for compress algorithms.
and at most 1 revocation sig on a subkey, as per 2440:11.1.
* hkp.c (parse_hkp_index, hkp_search): Error if the keyserver returns an
unparseable HKP response.
Show "[expired]" before expired uids.
* keyedit.c (show_key_with_all_names_colon), mainproc.c (list_node),
keylist.c (list_keyblock_colon): Use "uat" for user attribute packets
instead of "uid". Also use '<count> <length>' rather than the fake user
id string.
* misc.c (check_permissions): Check directory permissions properly - they
are not special files.
* pkclist.c (expand_id, expand_group, build_pk_list): When expanding
groups before building a pk list, inherit flags from the original
pre-expanded string.
* pubkey-enc.c (is_algo_in_prefs): Don't use prefs from expired uids.
show prefs on a v3 key with a v3 selfsig.
* kbnode.c (dump_kbnode): Show if a uid is expired.
* import.c (merge_blocks, import_revoke_cert): Show user ID receiving a
revocation certificate.
* free-packet.c (cmp_user_ids): Properly compare attribute ids.
Members of an expansion inherit their flags from the expansion key.
* options.h, cipher.c (write_header), g10.c (main), keygen.c
(keygen_set_std_prefs): remove the personal_mdc flag. It no longer serves
a purpose now that the personal preference lists are split into
cipher/digest/zip.
helpers. Also don't leak the last line worth of memory from the keyserver
response.
* main.h, misc.c (deprecated_warning): New function to warn about
deprecated options and commands.
* g10.c (main), keyserver-internal.h, keyserver.c (parse_keyserver_uri):
Use new deprecated function to warn about honor-http-proxy,
auto-key-retrieve, and x-broken-hkp.
they work properly on Solaris. Noted by David Champion.
Also, check for the Mozilla LDAP library if the OpenLDAP library check
fails. Put -lsocket and -lnsl in NETLIBS rather than LIBS so not all
programs are forced to link to them.
option "include-subkeys". This feature already existed, but now can be
turned off. It defaults to on.
* options.h, keyserver.c (parse_keyserver_options, keyserver_spawn): There
are now enough options to justify making a structure for the keyserver
options rather than a page of if-then-else-if-then-etc.
* getkey.c (merge_keys_and_selfsig, merge_selfsigs_main): Fix bug in
calculating key expiration dates.
user ID while importing a key. Note this applies to both --import and
keyserver --recv-keys.
* exec.c (exec_finish): Log unnatural exit (core dump, killed manually,
etc) for fork/exec/pipe child processes.
expand_groups), g10.c (main, add_group): Add new "group" command to allow
one name to expand into multiple keys. For simplicity, and to avoid
potential loops, we only expand once - you can't make an alias that points
to an alias.
* main.h, g10.c (main), keygen.c (build_personal_digest_list): Simplify
the default digest list - there is really no need for the other hashes
since they will never be used after SHA-1 in the list.
* options.skel, options.h, g10.c (main), hkp.c (hkp_ask_import,
hkp_export, hkp_search), keyserver.c (parse_keyserver_options,
parse_keyserver_uri, keyserver_work, keyserver_refresh): Make the
"x-broken-hkp" keyserver scheme into keyserver-option "broken-http-proxy".
Move honor_http_proxy into keyserver_options. Canonicalize the three
variations of "hkp", "x-hkp", and "x-broken-hkp" into "hkp".
default digest preference list consisting of SHA-1, followed by every
other installed digest except MD5. Note this is the same as having no
digest preference at all except for SHA-1 being favored.
* options.h, g10.c (main), keygen.c (keygen_set_std_prefs), pkclist.c
(select_algo_from_prefs): Split --personal-preference-list into three:
--personal-{cipher|digest|compress}-preferences. This allows a user to
set one without affecting another (i.e. setting only a digest pref doesn't
imply an empty cipher pref).
* exec.c (exec_read): This is a safer way of guessing the return value of
system(). Noted by Stefan Bellon.
unparseable responses.
* exec.c (exec_read): Catch and display an error when the remote process
exits unnaturally (i.e. segfault) so the user knows what happened. Also
fix exec_write stub which has a different number of arguments now.
* encode.c (encode_sesskey): New.
(encode_simple): Use it here. But by default we use the compat
mode which supress to generate encrypted session keys.
time, consult the various hash prefs to pick a hash algorithm to use.
Pass in a 160-bit hint if any of the signing keys are DSA.
* keydb.h, pkclist.c (select_algo_from_prefs, algo_available): Pass a
"hints" opaque pointer in to let the caller give hints as to what
algorithms would be acceptable. The only current hint is for
PREFTYPE_HASH to require a 160-bit hash for DSA. Change all callers in
encode.c (encode_crypt, encrypt_filter) and sign.c (sign_file). If we
settle on MD5 as the best algorithm based solely on recepient keys and
SHA1 is also a possibility, use SHA1 unless the user intentionally chose
MD5. This is as per 2440:13.
* exec.c (make_tempdir): Fix duplicated filename problem.
enum_sig_subpkt when a subpacket is critical and change all callers in
keylist.c (show_policy_url, show_notation), mainproc.c
(print_notation_data), and pkclist.c (do_show_revocation_reason).
* keylist.c (show_policy_url, show_notation): Display if the policy or
notation is critical.
list_keyblock_print, list_keyblock_colon), status.h, status.c
(get_status_string): New --attribute-fd feature to dump the contents of
attribute subpackets for frontends. If --status-fd is also used, then a
new status tag ATTRIBUTE is provided for each subpacket.
* packet.h, getkey.c (fixup_uidnode, merge_selfsigs_main,
merge_selfsigs_subkey), parse-packet.c (setup_user_id): Keep track of the
expiration time of a user ID, and while we're at it, use the expired flag
from the selfsig rather than reparsing the SIG_EXPIRE subpacket.
* photoid.c (generate_photo_id): When adding a new photo ID, showing the
photo for confirmation is not safe when noninteractive since the "user"
may not be able to dismiss a viewer window. Noted by Timo Schulz.
* misc.c (pct_expando): Use the seckey for %k/%K if the pubkey is not
available.
* photoid.h, photoid.c (show_photos): Include the seckey in case a user
tries to view a photo on a secret key, and change all callers in keyedit.c
(menu_showphoto), keylist.c (list_keyblock_print), and photoid.c
(generate_photo_id).
* hkp.c (parse_hkp_index): Properly handle the '&' character (i.e.
"&") in HKP responses.
* getkey.c (merge_selfsigs_main): Fix reversed expiration time check with
self-sigs.
* keyedit.c (sign_uids): When making a new self-sig on a v3 key, make a v3
self-sig unless it is currently a v3 self-sig being promoted to v4.
