int kcapi_kpp_ecdh_setcurve(struct kcapi_handle * handle, unsigned long curve_id);

handle

curve_id

With this function, the caller sets the ECC curve for subsequent cipher operations​. The curve ID is one of the ECC_CURVE_* identifiers​.

Note, this function defines that the subsequent key generation and shared secret operation performs an ECC Diffie-Hellman operation​.

return 0 upon success; a negative errno-style error code if an error occurred
