warning.
* sign.c (clearsign_file): Fix bug that prevents proper warning message
from appearing when clearsigning in --pgp2 mode with a non-v3 RSA key.
* main.h, misc.c (compliance_option_string, compliance_string,
compliance_failure), sign.c (sign_file, clearsign_file), encode.c
(encode_crypt, write_pubkey_enc_from_list): New functions to put the "this
message may not be usable...." warning in one place.
* options.h, g10.c (main): Part two of the simplification. Use a single
enum to indicate what we are compliant to (1991, 2440, PGPx, etc.)
encode.c, getkey.c, revoke.c: The current flags for different levels of
PGP-ness are massively complex. This is step one in simplifying them.
No functional change yet, just use a macro to check for compliance level.
(passphrase_to_dek): Ditto. Passed to above. Changed all
callers to pass NULL.
* seckey-cert.c (do_check): New arg CANCELED.
(check_secret_key): Terminate loop when canceled.
* keyedit.c (change_passphrase): Pass ERRTEXT untranslated to
passphrase_to_dek and translate where appropriate.
* seckey-cert.c (check_secret_key): Ditto.
* keygen.c (ask_passphrase): Ditto.
* passphrase.c (agent_get_passphrase): Translate the TRYAGAIN_TEXT.
Switch the codeset to utf-8.
pkclist.c (algo_available), revoke.c (gen_revoke): Add --pgp8 mode. This
is basically identical to --pgp7 in all ways except that signing subkeys,
v4 data sigs (including expiration), and SK comments are allowed.
* getkey.c (finish_lookup): Comment.
(get_pubkey_fast): this and made extern.
(get_pubkey_byfprint_fast): New.
* import.c (import_one): Use get_pubkey_fast instead of
get_pubkey. We don't need a merged key and actually this might
lead to recursions. --> There is still a problem, though.
(revocation_present): Likewise for search by fingerprint.
* g10.c (main): Try to create the trustdb even for non-colon-mode
list-key operations. This is required because getkey needs to
know whether a a key is ultimately trusted.
* 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.
