NAME
kcapi_kpp_ecdh_setcurve - set the ECC curve to be used for ECDH
SYNOPSIS
|
int kcapi_kpp_ecdh_setcurve(struct kcapi_handle * handle, unsigned long curve_id); |
ARGUMENTS
handle
[in] cipher handle
curve_id
[in] ID of the ECC curve
DESCRIPTION
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.
