kcapi_kpp_ecdh_setcurve — set the ECC curve to be used for ECDH
int kcapi_kpp_ecdh_setcurve ( | struct kcapi_handle * handle, |
unsigned long 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
