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.
section for random gatherers.
* keyring.c (create_tmp_file, rename_tmp_file): Create tmp files with
user-only permissions, but restore the original permissions if the user
has something special set.
* openfile.c (copy_options_file): Create new options file (gpg.conf) with
user-only permissions.
* keydb.c (keydb_add_resource): Create new keyrings with user-only
permissions.
for the hash that the sig is expecting. This can happen if a onepass sig
header does not match the actual sig, and also if the clearsign "Hash:"
header is missing or does not match the actual sig.
restarting gpg. This is Debian bug 124219, though their supplied patch
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.
clearsign_file): Use the same --pgpX warning string everywhere to ease
translations.
* encode.c (write_pubkey_enc_from_list): Warn when using --throw-keyid
with --pgpX. Noted by Vedaal Nistar.
(--import/export-options may be used as well). Document --import-options
and --export-options with their various options. --show-photos now works
during signature verification as well. Document --exec-path. Note in
--simple-sk-checksum that the passphrase must be changed for this to take
effect. Note that --pgp7 does not disable MDC. Document
--no-mdc-warning.
