WebJul 18, 2013 · When you call CryptGetHashParam (HP_HASHVAL), it serves as a signal that you aren't planning to add any more data to the hash, at which point the hash is finalized (the details depend on the algorithm; for MD5, padding bytes and length are appended). The resulting hash value cannot be added to.
