selfsig into both the pk and sk, so that someone importing their sk (which
will get an autoconvert to the pk) won't end up with two selfsigs.
(do_generate_keypair): Call it from here.
* parse-packet.c (can_handle_critical_notation): New. Check for
particular notation tags that we will accept when critical. Currently,
that's only preferred-email-encoding@pgp.com, since we know how to handle
it (pass it through to a mail program). (can_handle_critical): Call it
from here. (parse_one_sig_subpkt): Sanity check that notations are
well-formed in that the internal lengths add up to the size of the
subpacket.
(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.

comment packet.
* keygen.c (gen_elg, gen_dsa): Do not put public factors in secret key as
a comment.
* options.h, encode.c (encode_simple, encode_crypt), keygen.c (do_create):
Remove disabled comment packet code.
--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.

no-pubkey and chosen revocation cases. (clean_uid): New function to
clean a user ID of unusable (as defined by mark_usable_uid_certs)
certs.
* keyedit.c (keyedit_menu, menu_clean_uids): Call it here for new
"clean" command that removes unusable sigs from a key.
extra check for a bad passphrase and/or unknown cipher algorithm here.
We'll fail quite happily later, and usually with a better error
message to boot.
(add_keyserver_url): Use isascii() to protect the isfoo macros and
to replace direct tests. Possible problems noted by Christian

reader type specific.
(scan_or_find_devices): Do not check the interface subclass in the
SPR532 kludge, as this depends on the firmware version.
(ccid_get_atr): Get the Slot status first. This solves the
problem with readers hanging on recent Linux 2.6.x.
(bulk_in): Add argument TIMEOUT and changed all callers to pass an
appropriate one. Change the standard timeout from 10 to 5 seconds.

(do_close_reader): Do an usb_reset before closing the reader.
* mk-w32-dist: Check for patch files.
* w32installer.nsi: Translated a few more strings. Print a
warning if permssions are not suitable for the installation.
Add Uninstaller entries.
Fixes#423.
* DETAILS: Document new status codes.
* cardglue.c (agent_scd_pkdecrypt, agent_scd_pksign)
(agent_scd_genkey, agent_scd_setattr, agent_scd_change_pin)
(agent_scd_checkpin, agent_openpgp_storekey): Make sure to send a
SC_OP_FAILURE after card operations which might change data.
* card-util.c (change_pin): Send a SC_OP_SUCCESS after a PIN has
been changed.
(change_name): Removed a debug output.

interactive, do a --check_trustdb unless --no-auto-check-trustdb is
set.
* import.c (import_keys_internal): Moved from here.
* keyserver.c (keyserver_refresh): Call it here after all refreshing
has happened so that we don't rebuild after each preferred keyserver
set of imports, but do one big rebuild at the end. This is Debian bug
#293816, noted by Kurt Roeckx.
before the encryption key. This is a partial workaround for a PGP bug
(as of this writing, all versions including 8.1), that causes it to
try and encrypt to the most recent subkey regardless of whether that
subkey is actually an encryption type. In this case, the auth key is
an RSA key so it succeeds.
instead of 0x0000000000000000 for the invalid key ID since all-zeroes
is reserved for the anonymous recipient.
* keyedit.c (change_passphrase), keygen.c (generate_subkeypair): Fix a
string ;)
ask for the passphrase. Return an error if the primary key is a
plain stub.
* keyedit.c (change_passphrase): Don't ever change any stub key.
Print a note if a key consists of only stub keys. Reported by
Dany Nativel. These are bugs #401 and #402.
the cache. Changed all callers.
(get_one_do): Bypass the cache if the value would have been read
directly for v1.1 cards.It makes things a bit slower but obnly for
1.0 cards and there are not that many cards out in the wild. This
is required to fix a caching bug when generating new keys; as a
side effect of the retrieval of the the C4 DO from the 6E DO the
chaced fingerprint will get updated to the old value and later
when signing the generated key the checking of the fingerprint
fails becuase it won't match the new one. Thanks to Moritz for
analyzing this problem.
(verify_chv3): Removed the CHV status reread logic because we
won't cache the C4 DO anymore.

provided, default to '\n' or '\r\n' as appropriate. (is_armor_header):
Trim tabs in armor header lines as well.
* keyserver.c (keyserver_spawn): Use it here to force '\n' line endings
since the keyserver output file gets a LF->CRLF expansion on win32.
* armor.c (is_armor_header): Allow CR and LF (not just actual spaces) in
an armor header line (-----BEGIN etc). This is needed due to CRLF issues
on win32. As before, --openpgp makes it strict.
(scan_or_find_devices): Add new args to return endpoint info and
interface number.
(ccid_open_reader, ccid_shutdown_reader): Take care of these new
args.
(bulk_in, bulk_out): Use the correct endpoints.

subpacket at a time.
chosen selfsig so we don't accidentally promote an older selfsig to
chosen. Discovered by Simon Josefsson and 'Todd'.
* keygen.c (ask_expire_interval): Fix typo.
passphrase still wrong. Roman Pavlik found such a case.
* mpicoder.c (mpi_read_from_buffer): Don't abort in case of an
invalid MPI but print a message and return NULL. Use log_info and
not log_error.
* passphrase.c: Don't check for __CYGWIN__, so it is treated as a
unix-like system.
* options.h, g10.c (main), textfilter.c (standard): Use new option
--rfc2440-text to determine whether to filter "<space>\t\r\n" or just
"\r\n" before canonicalizing text line endings. Default to
"<space>\t\r\n".
temporary user ID.
* keyedit.c (keyedit_menu): Merge updpref and setpref. Keep updpref as an
invisible alias. Add invisible alias for revphoto. Fix small memory leak
when using "setpref" (not all of the uid was freed). (menu_revkey):
Trigger a trust rebuild after revoking a key. Don't allow revoking an
already-revoked whole key. (menu_revsubkey): Don't allow revoking an
already-revoked subkey.
Revoke a whole key. (keyedit_menu): Call it here for when 'revkey' is used
without any subkeys selected. This is to be consistent with the other
functions which are "selected part if selected, whole key if not".
exit if it cannot lock memory. Also remove --nrsign-key and --nrlsign-key
since this can better be done via --edit-key.
* secmem.c (secmem_init): Return a flag to indicate whether we got the
lock.
* memory.h: Return a flag to indicate whether we got the lock.

revoked.
* keyedit.c (show_key_with_all_names): Don't show validity for secret key
UIDs.
* keyedit.c (parse_sign_type): New. Figure out the flags (local,
nonrevoke, trust) for a signature. (keyedit_menu): Call it here so we can
mix and match flags, and don't need "nrltsign", "ltsign", "tnrsign", etc,
etc, etc.
(not used). (standard): 2440 says that textmode hashes should canonicalize
line endings to CRLF and remove spaces and tabs. 2440bis-12 says to just
canonicalize to CRLF. So, we default to the 2440bis-12 behavior, but
revert to the strict 2440 behavior if the user specifies --rfc2440. In
practical terms this makes no difference to any signatures in the real
world except for a textmode detached signature.
CUSTOM_DESCRIPTION. Changed all callers.
* app-openpgp.c (do_getattr, do_learn_status, do_setattr): Support
the new private DOs.
(do_change_pin): Add a "N" prefix to the strings so that the

unless --expert is given.
Set PUBKEY_USAGE_UNKNOWN to handle flags that we don't understand.
(fixup_uidnode, merge_selfsigs_main, merge_selfsigs_subkey): Call it from
here to remove duplicate code.
(parse_import_options, import_keys_internal): Make the import-options and
export-options distinct since they can be mixed together as part of
keyserver-options.

easier lining up of displays.
* keyedit.c (show_key_with_all_names), keylist.c (list_keyblock_print):
Use it here to print validity strings.
* gpgv.c: Stub.
(main): Unconditionally implement --status-file, --logger-file,
--attribute-file, --passphrase-file, --command-file. This is not

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

create file" to "can't create" to be consistent with other strings so we
don't have to translate both.

* app-openpgp.c (do_sign): Replace asprintf by direct allocation.
This avoids problems with missing vasprintf implementations.
* card-util.c (generate_card_keys): Add a #warning for gnupg 1.9
and use the same string there.

dash-space (i.e. a blank line that was quoted). Give a warning for bad
dash escaping.
trust since the meaning is different.
* keyedit.c (trustsig_prompt): Change the strings to match the ones in

there by the scdaemon which is a bit different to the direct
integration in gpg 1.3. In general they should all be maintained in

appropriate to strip policy and notations when remaking a sig. That
should only happen when specifically requested by the user.
uids are always on a line for themselves. Mark expired secret keys as
expired.
* options.h, g10.c (main): Rename list show-validity to show-uid-validity
as it only shows for uids.
* armor.c (armor_filter): Do not use padding to get us to 8 bytes of
header. Rather, use 2+4 as two different chunks. This avoids a fake
filename of "is".
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.
continuing confusion and make room for possible changes in devel.
* parse-packet.c (parse_plaintext): Show the hex value for the literal
packet mode since it may not be printable.
* keygen.c (make_backsig): Make sure that the backsig was built
successfully before we try and use it.
* status.h, status.c (get_status_string), plaintext.c (handle_plaintext):
New status tags PLAINTEXT and PLAINTEXT_LENGTH.
which we hashed them when issuing the signature. Noted by Nicholas Cole.
* pkclist.c (do_edit_ownertrust): Fix a kbnode leak and do another
keyid-format conversion.
keyservers, and auto-key-retrieve is set, try and get a missing key from
the preferred keyserver subpacket when we verify the sig.
* gpgv.c (parse_preferred_keyserver, free_keyserver_spec): Stubs.
* keyserver.c (keyidlist): Use new parse_preferred_keyserver function.
(keyserver_work): Use the passed-in keyserver spec rather than the options
global one.
* keyserver-internal.h, keyserver.c (parse_preferred_keyserver): New
function to take a sig and return a split out keyserver_spec.
(keyserver_import_keyid): Now takes a keyserver_spec.
merge selfsigs if we have to for honor-keyserver-url. (keyserver_refresh):
Keyserver URL handler moved here. (calculate_keyid_fpr): Removed.
* keydb.h, keyid.c (keystr_from_desc): Calculate a key string from a
KEYDB_SEARCH_DESC.
keyserver to happen even if there is no global keyserver set.
* sig-check.c (do_check_messages): No need to check for Elgamal signatures
any longer. (do_check_messages, do_check, check_key_signature2):
--keyid-format conversion.
* pkclist.c (show_paths, edit_ownertrust): Remove some unused code.
* mainproc.c (check_sig_and_print): track whether we are retrieving a key.
* status.c (status_currently_allowed): New. (write_status_text,
write_status_text_and_buffer): Use it here.
* g10.c: New command --gpgconf-list. (gpgconf_list): New. From Werner on
stable branch.
Improved URI parser that keeps track of the path information and doesn't
modify the input string. (keyserver_spawn): Tell keyserver plugins about
the path.
(list_one): Use const char* for i18n string helpers.
* keygen.c (do_generate_keypair, read_parameter_file): Really
close the files.
(do_generate_keypair): Create the secret key file using safe
permissions. Noted by Atom Smasher.
preferred keyserver on "keyserver" command line. Sanity check keyserver
URL before accepting it.
* keyserver-internal.h, g10.c (main), keyserver.c (parse_keyserver_uri):
Add an option to require the scheme:// and change all callers.
(free_keyserver_spec): Make public.
show. Don't allow a not-shown notation to prevent us from issuing the
proper --status-fd message.
* options.h, g10.c (main): Add show-std/standard-notations and
show-user-notations. show-notations is both. Default is to show standard
notations only during verify. Change all callers.
using key_byname to do the heavy lifting. Note that this also fixes an
old problem when the first key on the secret keyring has an unusable stub
primary, but is still chosen.
backsigs.
* getkey.c (merge_selfsigs_subkey): Find 0x19 backsigs on subkey selfsigs
and verify they are valid. If DO_BACKSIGS is not defined, fake this as
always valid.
* packet.h, parse-packet.c (parse_signature): Make parse_signature
non-static so we can parse 0x19s in self-sigs.
* main.h, sig-check.c (check_backsig): Check a 0x19 signature.
(signature_check2): Give a backsig warning if there is no or a bad 0x19
with signatures from a subkey.
parse_keyserver_options now returns a success code.
* keyserver.c (parse_keyserver_options): Return error on failure to parse.
Currently there is no way to fail as any unrecognized options get saved to
be sent to the keyserver plugins later. Check length of keyserver option
tokens since with =arguments we must only match the prefix.
(free_keyserver_spec): Moved code from parse_keyserver_url.
(keyserver_work, keyserver_spawn): Pass in a struct keyserver_spec rather
than using the global keyserver option. (calculate_keyid_fpr): New.
Fills in a KEYDB_SEARCH_DESC for a key. (keyidlist): New implementation
using get_pubkey_bynames rather than searching the keydb directly. If
honor-keyserver-url is set, make up a keyserver_spec and try and fetch
that key directly. Do not include it in the returned keyidlist in that
case.
requires end of line conversion. This is being considered for a UTF8 text
packet. If this doesn't take place, no major harm done. If it does take
place, we'll get a jump on starting the changeover.
* g10.c (main): --no-use-embedded-filename.
* build-packet.c (calc_plaintext, do_plaintext): Do not create illegal
(packet header indicates a size larger than the actual packet) encrypted
data packets when not compressing and using a filename longer than 255
characters.
* keyedit.c (no_primary_warning): Cleanup. (menu_expire): Don't give
primary warning for subkey expiration changes. These cannot reorder
primaries.
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.
and properly handle a partial match against an option with an argument.
* keyserver-internal.h, keyserver.c (parse_keyserver_options): Use new
optsep and argsplit functions.
which self-sig we actually chose.
* keyedit.c (menu_expire, menu_set_primary_uid, menu_set_preferences): Use
it here to avoid updating non-used self-sigs and possibly promoting an old
self-sig into consideration again.
keyserver.c (parse_keyserver_uri): Parse keyserver URI into a structure.
Cleanup for new "guess my keyserver" functionality, as well as refreshing
via a preferred keyserver subpacket.
functions in log_debug.
* import.c (import_one): Try and collapse user IDs when importing a key
for the first time.
* keyedit.c (menu_addrevoker): Allow appointing a subkey as a designated
revoker if the user forces it via keyid!, so long as the subkey can
certify. Also use the proper date string when prompting for confirmation.
* g10.c (main): Maintain ordering of multiple Comment lines. Requested by
Peter Hyman.

import_revoke_cert, chk_self_sigs, delete_inv_parts, merge_blocks): Still
more --keyid-format conversions.

list format since it is not much longer than regular 8-character short
keyids.
a key string from a key in one step. This isn't faster than before, but
makes for neater code.
* keylist.c (list_keyblock_print): Use keystr_from_xx here.
(print_key_data): No need to pass a keyid in.
support their pk algorithm. This allows for early (during get_*)
rejection of a subkey, and selection of another.
* passphrase.c (passphrase_to_dek): Give a little more information when we
have room to do so.
(passphrase_to_dek), keyserver.c (print_keyrec): A few more places to use
--keyid-format.
* options.h, g10.c (main), export.c (parse_export_options,
do_export_stream): Remove --export-all and the "include-non-rfc"
export-option as they are no longer meaningful with the removal of v3
Elgamal keys.
length mode and change all callers. (do_plaintext): Turn off partial
length encoding now that we're done writing the packet. (do_comment,
do_user_id): Try for a headerlen of 2 since that's the smallest and most
likely encoding for these packets.
* parse-packet.c (parse): Remove call to start old gpg partial length
mode.
replace the list-option (and eventually verify-option) show-long-keyids.
The format can be short, long, 0xshort, and 0xlong.
* keydb.h, keyid.c (keystr, keystrlen): New functions to generate a
printable keyid.
* keyedit.c (print_and_check_one_sig, show_key_with_all_names), keylist.c
(list_keyblock_print): Use new keystr() function here to print keyids.
(copy_packet, skip_packet, skip_rest, read_rest, parse_plaintext,
parse_encrypted, parse_gpg_control): Use a flag to indicate partial or
indeterminate encoding. This is the first step in some minor surgery to
remove the old gpg partial length encoding.
present if --expert is set.
* plaintext.c (handle_plaintext): Make bytecount static so it works with
multiple literal packets inside a message.
* encode.c, helptext.c (keygen.algo, keygen.algo.elg_se), keygen.c
(ask_algo), sig-check.c (do_check_messages), skclist.c (build_sk_list):
Rename "ElGamal" to "Elgamal" as that is the proper spelling nowadays.
Suggested by Jon Callas.
* encode.c (encode_simple): Show cipher with --verbose.
* options.h, g10.c (main), keyedit.c (sign_keys): Add --ask-cert-level
option to enable cert level prompts during sigs. Defaults to on.
Simplify --default-cert-check-level to --default-cert-level. If
ask-cert-level is off, or batch is on, use the default-cert-level as the
cert level.
* options.h, g10.c (main), trustdb.c (mark_usable_uid_certs): Simplify
--min-cert-check-level to --min-cert-level.
header lines, and include "sig:" records for the benefit of people who
store their keys in LDAP servers. It makes it easy to do queries for
things like "all keys signed by Isabella".
* Makefile.am: We get mkdtemp.c from libutil.a now, so don't link with
@LIBOBJS@.
* keyserver.c (keyserver_spawn): Pass the scheme to the keyserver helper.
along with a zero length, interpret this as an actual zero length packet
and not as an indeterminate length packet. (do_comment, do_user_id): Use
it here as these packets might be naturally zero length.
* parse-packet.c (parse): Show packet type when failing due to an
indeterminate length packet.
* misc.c (parse_options): Only provide args for the true (i.e. not
"no-xxx") form of options.

import.c (parse_import_options), g10.c (main): Use it here to allow for
options with optional arguments. Change all callers.
key to ensure that it does not advertise any that we cannot fulfill. Use
the keyedit command list function to optionally rewrite the prefs.
(import_one, import_secret_one): Use it here when importing a public key
that we have the secret half of, or when importing a secret key that we
have the public half of.
general command list functionality to replace it.
* g10.c (main): Use the general command functionality to implement
--sign-key, --lsign-key, --nrsign-key, and --nrlsign-key.
key, a revocation key set in a direct key signature, and a revocation from
that revocation key, all arrive piecemeal. Needless to say, this is pretty
obscure.
public subkeys.
* keylist.c (list_keyblock_print), keyedit.c (show_key_with_all_names):
Show the revocation date of a key/subkey, and general formatting work.
* packet.h, getkey.c (merge_selfsigs_main, merge_selfsigs_subkey,
merge_selfsigs): Keep track of the revocation date of a key.
* keydb.h, keyid.c (revokestr_from_pk): New function to print the
revocation date of a key.
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.

* 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.
Changed all callers.
* cardglue.c (pin_cb): Use it here, so the machine interface can
tell whether the Admin PIN is requested.
* cardglue.c (agent_scd_checkpin): New.

encrypted session key is seen without salt. Show in --list-packets if a
symetrically encrypted session key is present.

check_trustdb_stale (new), so that it can be called before validity is
checked.
* keylist.c (list_keyblock_print): Disable the overall key validity
display until it can be thought about more. Use check_trustdb_stale here
to avoid putting the check warning in the middle of a listed key.
* trustdb.c (init_trustdb): Only verify_own_keys() for those trust models
that it applies to (i.e. classic and OpenPGP).
