and one being DSA2 and encrypting at the same time, if the recipient
preferences give a hash that can work with the DSA2 key, then allow the
DSA1 key to be promoted rather than giving up and using hash_for().
keygen_add_std_prefs, proc_parameter_file): Add --default-keyserver-url to
specify a keyserver URL at key generation time, and "Keyserver:" keyword
for doing the same through a batch file.
(not a copy) of the stub secret key for the secret key we just
generated on the card. (generate_card_subkeypair): Use it here so
that the signing key on the card can use the card to generate the 0x19
backsig on the primary key. Noted by Janko Heilgeist and Jonas Oberg.
This prevents a memory allocation attack with a very large user ID. A
very large packet length could even cause the allocation (a u32) to wrap
around to a small number. Noted by Evgeny Legerov on full-disclosure.

on the key size. (ask_keysize, generate_keypair): Ask for DSA size when
--enable-dsa2 is set.
called with them closed. This is to protect our keyring/trustdb files
from corruption if they get attached to one of the standard fds. Print a
warning if possible that this has happened, and fail completely if we
cannot reopen (should never happen). (main): Call it here.
(build_sig_subpkt_from_sig), getkey.c (fixup_uidnode,
merge_selfsigs_main, merge_selfsigs_subkey), keygen.c
(keygen_add_key_expire): Fix meaning of key expiration and sig
expiration subpackets - zero means "never expire" according to 2440,
not "expire instantly".

* pkclist.c (algo_available): If --enable-dsa2 is set, we're allowed to
truncate hashes to fit DSA keys.
* sign.c (match_dsa_hash): New. Return the best match hash for a given q
size. (do_sign, hash_for, sign_file): When signing with a DSA key, if it
has q==160, assume it is an old DSA key and don't allow truncation unless
--enable-dsa2 is also set. q!=160 always allows truncation since they
must be DSA2 keys. (make_keysig_packet): If the user doesn't specify a
--cert-digest-algo, use match_dsa_hash to pick the best hash for key
signatures.
SHA-224.
* sign.c (write_plaintext_packet), encode.c (encode_simple): Factor
common literal packet setup code from here, to...
* main.h, plaintext.c (setup_plaintext_name): Here. New. Make sure the
literal packet filename field is UTF-8 encoded.
* options.h, gpg.c (main): Make sure --set-filename is UTF-8 encoded
and note when filenames are already UTF-8.
* keyedit.c (menu_backsign): Allow backsigning even if the secret
subkey doesn't have a binding signature.
* armor.c (radix64_read): Don't report EOF when reading only a pad (=)
character. The EOF actually starts after the pad.
* gpg.c (main): Make --export, --send-keys, --recv-keys,
--refresh-keys, and --fetch-keys follow their arguments from left to
right. Suggested by Peter Palfrader.
than 160 bits as per DSA2. This will allow us to verify and issue DSA2
signatures for some backwards compatibility once we start generating DSA2
keys.
* sign.c (do_sign), sig-check.c (do_check): Change all callers.
* sign.c (do_sign): Enforce the 160-bit check for new signatures here
since encode_md_value can handle non-160-bit digests now. This will need
to come out once the standard for DSA2 is firmed up.
same API as the other auto-key-locate fetchers.
* getkey.c (get_pubkey_byname): Use the fingerprint of the key that we
actually fetched. This helps prevent problems where the key that we
fetched doesn't have the same name that we used to fetch it. In the
case of CERT and PKA, this is an actual security requirement as the
URL might point to a key put in by an attacker. By forcing the use of
the fingerprint, we won't use the attacker's key here.

* keyedit.c (menu_backsign): Small tweak to work properly with keys
originally generated with older GnuPGs that included comments in the
secret keys.

* keyedit.c (menu_set_notation): Use it here to allow deleting a notation
marked with '-'. This works with either "-notation" or "-notation=value".
