Description
Uses the first 16 bytes from HashData to create a Guid. The first 16 bytes of HashData should be premixed to include all cryptographically necessary bytes from the hash to describe larger dataset, so that changing any byte of the dataset will change the first 16 bytes of HashData. If HashData is less than 16 bytes, it is padded with 0 to create the guid.
