a5d03c54ab Corrected OPENSSL_NO_EC_NISTP_64_GCC_128 usage in ec_lcl.h. PR#3370 2014-06-03 23:17:21 +01:00

3d520f7c2d Fix warnings.
Also, use the common Configure mechanism for enabling/disabling the 64-bit ECC code.

9c37519b55 Improve optional 64-bit NIST-P224 implementation, and add NIST-P256 and
NIST-P521. (Now -DEC_NISTP_64_GCC_128 enables all three of these;
-DEC_NISTP224_64_GCC_128 no longer works.)

69e2ec63c5 Reorganise ECC code so it can use FIPS module.
Move compression, point2oct and oct2point functions into separate files.

Add a flags field to EC_METHOD.

Add a flag EC_FLAGS_DEFAULT_OCT to use the default compession and oct functions
(all existing methods do this). This removes dependencies from EC_METHOD while
keeping original functionality.

Backport from HEAD with minor changes.

48ce525d16 New 64-bit optimized implementation EC_GFp_nistp224_method().
Binary compatibility is not affected as this will only be
compiled in if explicitly requested (#ifdef EC_NISTP224_64_GCC_128).

9dd8405341 ecc api cleanup; summary:
- hide the EC_KEY structure definition in ec_lcl.c + add
  some functions to use/access the EC_KEY fields
- change the way how method specific data (ecdsa/ecdh) is
  attached to a EC_KEY
- add ECDSA_sign_ex and ECDSA_do_sign_ex functions with
  additional parameters for pre-computed values
- rebuild libeay.num from 0.9.7

0f814687b9 Deprecate the recursive includes of bn.h from various API headers (asn1.h,
dh.h, dsa.h, ec.h, ecdh.h, ecdsa.h, rsa.h), as the opaque bignum types are
already declared in ossl_typ.h. Add explicit includes for bn.h in those C
files that need access to structure internals or API functions+macros.

ba729265a8 Allow EC_GROUP objects to share precomputation for improved memory
efficiency (EC_PRE_COMP objects are now constant once completed).

Extend 'extra_data' API to support arbitrarily many slots (although we
need only one at the moment).

Modify EC internal 'extra_data' API: EC_GROUP_[clear_]free_extra_data
now frees only a single slot (the previous functions are available as
EC_GROUP_[clear_]free_all_extra_data).

35b73a1f20 Rename implementations of method functions so that they match
the new method names where _GF... suffixes have been removed.

Revert changes to ..._{get/set}_Jprojective_coordinates_...:
The current implementation for ECC over binary fields does not use
projective coordinates, and if it did, it would not use Jacobian
projective coordinates; so it's OK to use the ..._GFp prefix for all
this.

Add author attributions to some files so that it doesn't look
as if Sun wrote all of this :-)
