ANSIX963KDF_generate()

MOC_EXTERN MSTATUS ANSIX963KDF_generate	(	MOC_HASH(hwAccelDescr hwAccelCtx) const BulkHashAlgo *	pBulkHashAlgo,
		ubyte *	z,
		ubyte4	zLength,
		const ubyte *	sharedInfo,
		ubyte4	sharedInfoLen,
		ubyte4	retLen,
		ubyte	ret[]
	)

Performs the ANSI x9.63 Key Derivation.

Parameters

pBulkHashAlgo	Pointer to a suite holding the function pointer hash methods to be used.
z	Buffer holding the input shared secret as a byte array.
zLength	The length of z in bytes.
sharedInfo	Optional. Buffer holding the shared info as a byte array.
sharedInfoLen	The length of the shared info in bytes.
retLen	The requested length of the derived key in bytes.
ret	Buffer that will hold the resulting derived key.

Returns

OK (0) if successful; otherwise a negative number error code definition from merrors.h.
