Dr. Stephen Henson 29dc350813 Rebuild error codes. 2005-04-12 16:15:22 +00:00
Bodo Möller 62e3163b1b ECPublicKey_set_octet_string and ECPublicKey_get_octet_string 
behaviour was not quite consistent with the conventions
for d2i and i2d functions as far as handling of the 'out'
or 'in' pointer is concerned.

This patch changes this behaviour, and renames the functions to
o2i_ECPublicKey and i2o_ECPublicKey (not 'd2i' and 'i2d' because the
external encoding is just a raw object string without any DER icing).

Bodo Möller 7eb18f1237 Simplify handling of named curves: get rid of EC_GROUP_new_by_name(), 
EC_GROUP_new_by_nid() should be enough.  This avoids a lot of

Bodo Möller 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 :-)

Bodo Möller 3ba1f11147 Improve EC efficiency. 2001-11-15 22:32:11 +00:00
Bodo Möller 4f69172d25 Completely remove mont2 stuff. 
It does not appear to be faster than the current Montgomery code
except for very small moduli (somewhere between 192 and 224 bits
in a 64-bit Sun environment, and even less than 192 bits
on 32 bit systems).

that applications can request precomputation when appropriate.
