(pubkey_get_npkey): Return 2 for RSA even if it isn't available so we can
at least handle RSA keys.
----------------------------------------------------------------------
pubkey.c CVS:

--override-session-key on --symmetric messages (new-style or old-style).
(proc_pubkey_enc): Move code to show session key from here to
proc_encrypted() so it can work with any type of message. Suggested by
Michael Young.
any ultimately trusted keys. This ensures that if we lose all our
ultimately trusted keys, we don't leave behind the old validity
calculations. Noted by Peter Palfrader.
* revoke.c (gen_desig_revoke): Specify in the comment when a designated
revocation is generated.
* getkey.c (merge_selfsigs_main, merge_selfsigs_subkey,
get_seckey_byname2): Remove Elgamal check since we are removing type 20
keys altogether.
Document --bzip2-compress-level, and --bzip2-compress-lowmem. Clarify the
plurarility (or not) of various list and verify options. Document BZIP2
in the --compress-algo section. Warn about compatibility issues with ZLIB
and BZIP2.
* misc.c (compress_algo_to_string): Translate "Uncompressed". Requested by
Tommi Vainikainen. (string_to_compress_algo): Include multi-string for
"uncompressed|none".
string with tokens separated by |. (answer_is_yes_no_default,
answer_is_yes_no_quit, answer_is_okay_cancel): Use it here to enable
alternate translations.
"external" trust model, where the user can provide a pregenerated trustdb.
* keyedit.c (keyedit_menu): Do not allow editing ownertrust with an
external trust model trustdb.
* main.h, encode.c (setup_symkey): New. Prompt for a passphrase and
create a DEK for symmetric encryption. (write_symkey_enc): New. Write out
symmetrically encrypted session keys. (encode_crypt, encrypt_filter): Use
them here here when creating a message that can be decrypted with a
passphrase or a pk.
* sign.c (sign_file): Call setup_symkey if we are doing a --symmetric
--sign --encrypt.
--quiet is set. Suggested by Duncan Harris. Also don't fail with BUG()
when processing a --symmetric message with a cipher we don't have.
* g10.c: Alias --personal-xxx-prefs to --personal-xxx-preferences.
list of ultimately trusted keys.
* keygen.c (do_generate_keypair): Use it here so that the ultimate
ownertrust happens before the trustdb (might be) rebuilt. Also fix an
error where the newly generated pk is thought to be a subkey by the
trustdb.
* g10.c (main): Fix --export-all do actually do something different than
--export.
* pkclist.c (build_pk_list): Show all recipients rather than showing each
recipient as they are added.
* mainproc.c (proc_symkey_enc, proc_encrypted): Keep a count of the number
of passphrases that can decrypt a symmetric or mixed symmetric/pk message
and include it in the list of keys shown to the user.
check_compress_algo): Add bzip2.
* compress.c (compress_filter): Make static to help force the use of
push_compress_filter. Remove default algorithm setting since that is done
in push_compress_filter now.
* main.h: Use named algorithm.
* filter.h, compress.c (push_compress_filter, push_compress_filter2): New.
Figure out which is the appropriate compression filter to use, and push it
into place.
* compress.c (handle_compressed), encode.c (encode_simple, encode_crypt),
sign.c (sign_file, sign_symencrypt_file), import.c (read_block), export.c
(do_export): Use push_compress_filter instead of pushing the compression
filter ourselves.
* compress-bz2.c: New. Bzlib versions of the compression filter routines.
* Makefile.am: Include compress-bz2.c if bz2lib is available.
* keylist.c (list_keyblock_print): Denote secrets keys stored on a
card with an '>'. Print the '#' also for subkeys.
(list_keyblock_colon): Introduce new field 15 for sec/ssb to print
the serial number.
message that can be decrypted via a passphrase or public key system.
* main.h, encode.c (encode_seskey): Allow passing in an already-created
session key dek. (encode_simple): Use the actual symmetric cipher when
encrypting a session key for a symmetric message. (encode_crypt): Add a
flag to trigger a hybrid mode that can be decrypted via a passphrase or a
pk. Change all callers.
* mainproc.c (symkey_decrypt_sesskey): There is no way to tell the
difference here between a bad passphrase and a cipher algorithm that we
don't have, so use a error message that makes that clear. Use the actual
list of ciphers when checking whether a cipher is invalid. Return error
if the decrypted cipher algorithm is invalid. (proc_symkey_enc): In a
mixed passphrase/pk message, if a valid dek already exists from decrypting
via pk, do not try to process the passphrase. (proc_symkey_enc): Indicate
when we're decrypting a session key as opposed to decrypting data. If a
passphrase is invalid, discard the dek so we'll keep trying.
