v3 keys are deprecated for about 15 years and due the severe
weaknesses of MD5 it does not make any sense to keep code around to
use these old and broken keys.  Users who need to decrypt old messages
should use gpg 1.4 and best re-encrypt them to modern standards.
verification of old (i.e. PGP2) created signatures is thus also not
anymore possible but such signatures have no values anyway - MD5 is
just too broken.

We have also kept support for v3 signatures until now.  With the
removal of support for v3 keys it is questionable whether it makes any
sense to keep support for v3-signatures.  What we do now is to keep
support for verification of v3-signatures but we force the use of
v4-signatures.  The latter makes the --pgp6 and --pgp7 switch a bit
obsolete because those PGP versions require v3-signatures for
messages.  These versions of PGP are also really old and not anymore
maintained so they have not received any bug fixes and should not be
used anyway.

Werner Koch 457bce5cd3 gpg: Improve passphrase caching.
* agent/cache.c (last_stored_cache_key): New.
(agent_get_cache): Allow NULL for KEY.
(agent_store_cache_hit): New.
* agent/findkey.c (unprotect): Call new function and try to use the
last stored key.

* g10/revoke.c (create_revocation): Add arg CACHE_NONCE and pass to
make_keysig_packet.
(gen_standard_revoke): Add arg CACHE_NONCE and pass to
create_revocation.
* g10/keygen.c (do_generate_keypair): Call gen_standard_revoke with
cache nonce.
--

This patch adds two features:

1. The key for the last passphrase successfully used for unprotecting
a key is stored away.  On a cache miss the stored away passphrase is
tried as well.  This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase.  See the
code for more comments.

2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt.  Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).

Werner Koch 2b8d8369d5 gpg: Remove options --pgp2 and --rfc1991.
* g10/gpg.c (oRFC1991, oPGP2): Remove
(opts): Remove --pgp2 and --rfc1991.
* g10/options.h (CO_PGP2, CO_RFC1991): Remove.  Remove all users.

--

The use of PGP 2.c is considered insecure for quite some time
now (e.g. due to the use of MD5).  Thus we remove all support for
_creating_ PGP 2 compatible messages.

The gpg server mode is not actual working and thus we can avoid the
warnings by explicitly disabling the mode.  We keep it working under
Unix, though.

Without this patch, pk2 would be freed twice.

Subject: [PATCH] avoid use of freed pointer

If we free pk2 at the top of the for-loop, set it to NULL
so that we don't free it again just before returning.
* revoke.c (gen_desig_revoke): Don't use pk2 after freeing it.

Werner Koch 5da12674ea Fix regression in gpg's mail address parsing.
Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'.  This happened when I merged the user id
classification code of gpgsm and gpg.

Werner Koch b008274afd Nuked almost all trailing white space.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces.  In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much.  For future commits the pre-commit scripts
checks that this won't happen again.

Werner Koch c0c2c58054 Finished the bulk of changes for gnupg 1.9. This included switching
to libgcrypt functions, using shared error codes from libgpg-error,
replacing the old functions we used to have in ../util by those in
../jnlib and ../common, renaming the malloc functions and a couple of
types.  Note, that not all changes are listed below becuause they are
too similar and done at far too many places.  As of today the code
builds using the current libgcrypt from CVS but it is very unlikely
that it actually works.
