-- These are non-substantive corrections for minor spelling mistakes within the GnuPG codebase.

2011-06-13Fix for latest fix in Libgcrypt.Werner Koch1-1/+1
2011-02-03Finished ECC integration.ECC-INTEGRATION-2-1Werner Koch1-2/+0
Wrote the ChangeLog 2011-01-13 entry for Andrey's orginal work modulo the cleanups I did in the last week. Adjusted my own ChangeLog entries to be consistent with that entry. Nuked quite some trailing spaces; again sorry for that, I will better take care of not saving them in the future. "git diff -b" is useful to read the actual changes ;-). The ECC-INTEGRATION-2-1 branch can be closed now.
2011-02-02Compute the fingerprint for ECDH only on demand.Werner Koch1-9/+18
This also fixes a failed assertion when using a v3 key where the fingerprint size is not 20.
2011-01-31Fixed the ECC interface to Libgcrypt to be ABI compatible with the previous ↵Werner Koch1-2/+2
version. 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 .
2011-01-31Reworked the ECC changes to better fit into the Libgcrypt API.Werner Koch1-12/+36
See ChangeLog for details. Key generation, signing and verification works. Encryption does not yet work. Requires latest Libgcrypt changes.
2011-01-25Started with some code cleanups in ECDH.Werner Koch1-13/+57
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.
2011-01-21Editorial changes and allow building with old libgcrypts.Werner Koch1-85/+26
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 <[email protected]> * configure.ac: Need Libgcrypt 1.4.6 due to AESWRAP. (HAVE_GCRY_PK_ECDH): Add new test. [agent/] 2011-01-21 Werner Koch <[email protected]> * cvt-openpgp.c (GCRY_PK_ECDH) [!HAVE_GCRY_PK_ECDH]: New. [include/] 2011-01-21 Werner Koch <[email protected]> * cipher.h (GCRY_PK_USAGE_CERT): Remove compatibility macros because we now require libgcrypt 1.4.6. (GCRY_PK_ECDH): Add replacement.
2011-01-11'g10/gpg2 --encrypt --debug 15 -r ecdsa -a -o _e.asc _' and 'g10/gpg2 ↵Andrey Jivsov1-74/+0
--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
2011-01-06Integrating http://code.google.com/p/gnupg-ecc/source/detail?r=15 .Andrey Jivsov1-10/+141
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.

Rename function in a simlar way. Re-indent encrypt.c
