importing at -r time. The URL in the PKA record may point to a key put in
by an attacker. Fix is to use the fingerprint from the PKA record as the
recipient. This ensures that the PKA record is followed.
* keyserver-internal.h, keyserver.c (keyserver_import_pka): Return the
fingerprint we requested.
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.
(keyserver_import_pka), card-util.c (fetch_url): Always require a
scheme:// for keyserver URLs except when used as part of the
--keyserver command for backwards compatibility.
card. If it does, only allow 160-bit hashes, a la DSA. This involves
passing the *sk in, so change all callers. This is correct for today,
given the current 160-bit q in DSA, and the current SHA-1/RIPEMD160
support in the openpgp card. It will almost certainly need changing
down the road.
* app-openpgp.c (do_sign): Give user error if hash algorithm is not
supported by the card.
getkey.c:get_pubkey_byname which was getting crowded.
* keyserver.c (keyserver_import_cert): Import a key found in DNS via CERT
records. Can handle both the PGP (actual key) and IPGP (URL) CERT types.
* getkey.c (get_pubkey_byname): Call them both here.
* options.h, keyserver.c (parse_keyserver_options): Add
"auto-cert-retrieve" option with optional max size argument.
* keyserver-internal.h, keyserver.c (keyserver_spawn, keyserver_work,
keygerver_getname): New keyserver_getname function to fetch keys by name.
* getkey.c (get_pubkey_byname): Call it here to enable locating keys by
full mailbox from a keyserver a la PKA. Try PKA first, though, as it is
likely to be faster.
curl_writer_finalize): New functionality to handle binary format keys by
armoring them for input to GPG.
* gpgkeys_curl.c (get_key), gpgkeys_hkp.c (get_key): Call it here.
keyserver_fetch): Set a flag to indicate that we're doing a direct URI
fetch so we can differentiate between a keyserver operation and a URI
fetch for protocols like LDAP that can do either.
when fetching a URI.
* keyserver-internal.h, keyserver.c (keyserver_fetch): New. Fetch an
arbitrary URI using the keyserver helpers.
* gpg.c (main): Call it from here for --fetch-keys.
