Function Documentation

PKIFCryptoPPExternalDigestAccumulator* NewEDAccumulator	(	unsigned char *	digest,
		size_t	len
	)

Interface: Module Create a new MessageAccumulator that uses the external digest class instead of one that expects to calculate the digest using Update() repeatedly

Returns:

newly allocated ExternalDigestAccumulator The caller is responsible for freeing it, but if it's used with Verify() it will be freed by crypto++ inside the Verify() routine.

Parameters:

digest	[in] pre-calculated message digest to use with the accumulator
len	[in] size in bytes of the digest buffer
