When overridden in a derived class, routes data written to the object into the SHA512Managed hash algorithm for computing the hash.
Assembly: mscorlib (in mscorlib.dll)
This method is not called by application code.
This abstract method performs the hash computation. Every write to the cryptographic stream object passes the data through this method. For each block of data, this method updates the state of the hash object so a correct hash value is returned at the end of the data stream.
