Hi, guys
We work on openssl-1.0.0.a
When we want support HW acceleration of ECC algorithm, we find two kind of
limitations in engine support for ECC.
First, there is no engine mechanism to accelerate ECC mult.
Secondly, we find that ECDSA_METHOD or ECDH_METHOD is defined in ech_locl.h
which is not a public include file.
And we explore the package and don't find any interface to get or set the
members of ECxxx_METHOD.
So, does it means we had to patch the openssl package to accelerate ECDH or
ECDSA?
This is the same issue as reported in #2459 from 2/23/2011 by Kent Yoder,
and I have run into this same issue with the OpenSC engine_pkcs11 code that
requires ecs_locl.h to get the ECDSA_METHOD.
So OpenSC is looking for a fix too.
