* encode.c (encode_sesskey): Checked the code and removed
the warning since all compatibility checks with PGP succeeded.
* mainproc.c (symkey_decrypt_sesskey): Better check for the
algorithm and check the return values of some functions.
to libgcrypt functions, using shared error codes from libgpg-error,
replacing the old functions we used to have in ../util by those in
../jnlib and ../common, renaming the malloc functions and a couple of
types. Note, that not all changes are listed below becuause they are
too similar and done at far too many places. As of today the code
builds using the current libgcrypt from CVS but it is very unlikely
that it actually works.
* 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.
(get_user_id_printable): this. Filter out all dangerous
characters. Checked all usages.
(get_user_id_string_native): Renamed to..
(get_user_id_string_printable): this. Filter out all dangerous
characters. Checked all usages.
* keyedit.c (show_basic_key_info): New.
* keylist.c (print_fingerprint): New mode 3.
* import.c (import_one): Use new function to display the user ID.
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.
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.
