like "fully trusted", "marginally trusted", etc. (get_min_ownertrust):
New. Return minimum ownertrust. (update_min_ownertrust): New. Set
minimum ownertrust. (check_regexp): New. Check a regular epression
against a user ID. (ask_ownertrust): Allow specifying a minimum value.
(get_ownertrust_info): Follow the minimum ownertrust when returning a
letter. (clear_validity): Remove minimum ownertrust when a key becomes
invalid. (release_key_items): Release regexp along with the rest of the
info. (validate_one_keyblock, validate_keys): Build a trust sig chain
while validating. Call check_regexp for regexps. Use the minimum
ownertrust if the user does not specify a genuine ownertrust.
* pkclist.c (do_edit_ownertrust): Only allow user to select a trust level
greater than the minimum value.
* parse-packet.c (can_handle_critical): Can handle critical trust and
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.
* 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.
* export.c (do_export_stream): Fix noop bug in exporting sensitive
revocation keys.
* pkclist.c (do_edit_ownertrust): Comment out the option for showing trust
paths until it can be implemented.
symmetric compressed files.
* encode.c (encode_simple, encode_crypt): If we are not using a MDC,
compress even if a file is already compressed. This is to help against
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
if the keys directly support it, if the keys list AES (any) or TWOFISH
anywhere in the prefs, or if the cipher chosen does not have a 64 bit
blocksize.
