A wrapper stream that calculates a hash of the base stream as it is being read or written. The calculated hash is only available after the stream is closed or CalculateHash is called. After calling CalculateHash, any further reads on the streams will not change the CalculatedHash. If an ExpectedHash is specified and is not equal to the calculated hash, Close or CalculateHash methods will throw an ClientException. If base stream's position is not 0 or HashOnReads is true and the entire stream is not read, the CalculatedHash will be set to an empty byte array and comparison to ExpectedHash will not be made.
