This is useful because for Libgcrypt we specify the algorithm in the S-expressions and the public key ids are not anymore needed. This patch also adds some support for PUBKEY_ALGO_EDDSA which will eventually be used instead of merging EdDSA with ECDSA. As of now an experimental algorithm id is used but the plan is to write an I-D so that we can get a new id from the IETF. Note that EdDSA (Ed25519) does not yet work and that more changes are required. The ECC support is still broken right now. Needs to be fixed. Signed-off-by: Werner Koch <wk@gnupg.org>

* Compute the fingerprint for ECDH only on demand.Werner Koch2011-02-021-3/+4
| | | | | This also fixes a failed assertion when using a v3 key where the fingerprint size is not 20.
* Reworked the ECC changes to better fit into the Libgcrypt API.Werner Koch2011-01-311-1/+1
| | | | | See ChangeLog for details. Key generation, signing and verification works. Encryption does not yet work. Requires latest Libgcrypt changes.
* Started with some code cleanups in ECDH.Werner Koch2011-01-251-0/+7
| | | | | | The goal is to have the ECDH code more uniform with the other algorithms. Also make error messages and variable names more similar to other places.

* Editorial changes and allow building with old libgcrypts.Werner Koch2011-01-211-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. [/] 2011-01-21 Werner Koch <wk@g10code.com> * configure.ac: Need Libgcrypt 1.4.6 due to AESWRAP. (HAVE_GCRY_PK_ECDH): Add new test.

| | | | | | | | --debug 15 _e.asc', as well as decoding of an old message posted on https://sites.google.com/site/brainhub/pgpecckeys work. This is the milestone 2 that brings in ECDH support from http://code.google.com/p/gnupg-ecc/source/detail?r=15 . This corresponds to the commit 899386826c85f1e757e75bcc5d5b2159d05676a0 in libgcrypt
* Integrating http://code.google.com/p/gnupg-ecc/source/detail?r=15 .Andrey Jivsov2011-01-061-1/+11
| | | | | | | | | | 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.

* Finished the bulk of changes for gnupg 1.9. This included switchingWerner Koch2003-06-181-0/+34
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.
