Quite some changes were needed but in the end we have less code than
before. Instead of trying to do everything with MPIs and pass them
back and forth between Libgcrypt and GnuPG, we know use the
S-expression based interface and make heavy use of our opaque MPI
feature.
Encryption, decryption, signing and verification work with
self-generared keys.
Import and export does not yet work; thus it was not possible to check
the test keys at https://sites.google.com/site/brainhub/pgpecckeys .
Changed order of some conditional to make to put the special case into
the true branch. Indentation changes. Minor other changes to make the
ECC code more similar to the rest of our code.
It builds but many sefltests still fail. Need to fix that before
using it with an ECDH enabled libgcrypt.

* configure.ac: Need Libgcrypt 1.4.6 due to AESWRAP.
(HAVE_GCRY_PK_ECDH): Add new test.
[agent/]
2011-01-21 Werner Koch <wk@g10code.com>
* cvt-openpgp.c (GCRY_PK_ECDH) [!HAVE_GCRY_PK_ECDH]: New.
[include/]
2011-01-21 Werner Koch <wk@g10code.com>
* cipher.h (GCRY_PK_USAGE_CERT): Remove compatibility macros
because we now require libgcrypt 1.4.6.
(GCRY_PK_ECDH): Add replacement.
The following works:
gpg2 --gen-key (ECC)
gpg2 --list-keys
gpg2 --list-packets ~/.gnupg/pubring.gpg
gpg2 --list-packets <private key from http://sites.google.com/site/brainhub/pgpecckeys>
ECDH doesn't work yet as the code must be re-written to adjust for gpg-agent refactoring.
* seskey.c (encode_session_key): Debug output of the session key.
* pubkey-enc.c (get_it): Handle card case.
* call-agent.c (agent_scd_pkdecrypt): New.
* pkglue.c (pk_encrypt): Add RSA support.
* g10.c (main): Default to --use-agent.
* keygen.c (show_smartcard): Print info about the public key.
(check_smartcard): Check for existing key here.
(gen_card_key): And not anymore here.
(fpr_is_zero): New.
(generate_keypair): Generate both keys for a card.
(smartcard_change_url): Nw.
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.
