CIMPORT_C CRYSError_t CRYS_ECDH_SVDP_DH	(	CRYS_ECPKI_UserPublKey_t *	PartnerPublKey_ptr,
		CRYS_ECPKI_UserPrivKey_t *	UserPrivKey_ptr,
		uint8_t *	SharedSecretValue_ptr,
		uint32_t *	SharedSecrValSize_ptr,

	)

Creates the shared secret value according to [IEEE1363, ANS X9.63]:

Checks input-parameter pointers and EC Domain in public and private keys.
Derives the partner public key and calls the EcWrstDhDeriveSharedSecret function, which performs EC SVDP operations.

Note:: The term "User" refers to any party that calculates a shared secret value using this primitive. The term "Partner" refers to any other party of shared secret value calculation. Partner's public key shall be validated before using in this primitive.

Returns:: CRYS_OK on success.; A non-zero value on failure as defined crys_ecpki_error.h.

Parameters:

[in]	PartnerPublKey_ptr	Pointer to a partner public key.
[in]	UserPrivKey_ptr	Pointer to a user private key.
[out]	SharedSecretValue_ptr	Pointer to an output buffer that will contain the shared secret value.
[in,out]	SharedSecrValSize_ptr	Pointer to the size of user-passed buffer (in) and actual size of output of calculated shared secret value (out).
[in]	TempBuff_ptr	Pointer to a temporary buffer.
