#define ECC_LARGEST_CURVE_SIZE   (32)

The size of the the largest supported EC. For now, assuming the 256-bit EC is the largest supported curve type.

#define ECC_NUM_SUPP_CURVES   ((sizeof(gastrECCSuppList)) / (sizeof(tstrEllipticCurve)))

#define ECC_POINT_MAX_SIZE   ECC_LARGEST_CURVE_SIZE

Maximum size of one coordinate of an EC point.

#define ECC_POINT_MAX_SIZE_WORDS   (ECC_POINT_MAX_SIZE / 4)

SIZE in 32-bit words.
