I have a signing function, currently implemented in OpenSSL, that i'd like to convert to libgcrypt. However I can't seem to find good docks on ECDSA - specifically the gcrypt equivalent of EC_GROUP_new_curve_GFp(), EC_POINT_set_affine_coordinates_GF2m(), EC_GROUP_set_generator(), EC_KEY_set_group(), EC_KEY_get0_group(). Any help (example?) would be great! :) Thanks!
