Thanks Remy for asking the question in my mind. "ENGINE_set_default_EC_METHOD" will be perfect to offload EC Point multiplication, doubling and addition offered by some h/w crypto accelerators. Hi Matt, What is the reason to keep ec_method, ecdh_method and ecdsa_method structure definitions in local header files ec_locl.h, ech_locl.h and ecs_locl.h respectively unlike their peers.. dh_method, dsa_method, rsa_meth_st and rand_meth_st which are defined in exported header files? ENGINE_set_default_EC_METHOD is really nice idea. Even if it is not immediate, please discuss the possibility of having this with your team. Thanks, Thulasi.
