* cipher/idea.c: New. Take from Libgcrypt master and adjust for
direct use in GnuPG.
* cipher/idea-stub.c: Remove.
* cipher/Makefile.am: Add idea.c and remove idea-stub.c rules.
* configure.ac: Remove idea-stub code.
* g10/gpg.c (check_permissions): Remove code path for ITEM==2.
(main): Make --load-extension a dummy option.
* g10/keygen.c (keygen_set_std_prefs): Include IDEA only in PGP2
compatibility mode.
* g10/misc.c (idea_cipher_warn): Remove. Also remove all callers.
* g10/seckey-cert.c (do_check): Remove emitting of STATUS_RSA_OR_IDEA.
* g10/status.c (get_status_string): Remove STATUS_RSA_OR_IDEA.
* g10/status.h (STATUS_RSA_OR_IDEA): Remove.
--
To keep the number of actually used algorithms low, we support IDEA
only in a basically read-only way (unless --pgp2 is used during key
generation). It does not make sense to suggest the use of this old 64
bit blocksize algorithm. However, there is old data available where
it might be helpful to have IDEA available.
passphrase as if it was used (move from next_pw to last_pw).
* pubkey-enc.c (get_session_key): Use it here to handle the case where a
passphrase happens to be correct for a secret key, but yet that key isn't
the anonymous recipient (i.e. the secret key could be decrypted, but not
the session key). This also handles the case where a secret key is
located on a card and a secret key with no passphrase. Note this does not
fix bug 594 (anonymous recipients on smartcard do not work) - it just
prevents the anonymous search from stopping when the card is encountered.
* encode.c (encode_simple): Allow for 32 bytes (256 bits) of symmetrically
encrypted session key. Use --s2k-cipher-algo to choose cipher, rather
than the default cipher.
* parse-packet.c (parse_subkeyenc): Give a warning if an symmetrically
encrypted session key is seen without salt. Show in --list-packets if a
symetrically encrypted session key is present.
* pubkey-enc.c (get_it): Always show cipher-not-in-prefs warning unless
--quiet is set. Use text name of cipher in warning.
passphrase against all secret keys rather than trying all secret keys in
turn. Don't if --try-all-secrets or --status-fd is enabled.
* passphrase.c (passphrase_to_dek): Mode 1 means do a regular passphrase
query, but don't prompt with the key info.
* seckey-cert.c (do_check, check_secret_key): A negative ask count means
to enable passphrase mode 1.
* keydb.h, getkey.c (enum_secret_keys): Add flag to include
secret-parts-missing keys (or not) in the list.
