clone in class AbstractMessageDigest

Returns:

a clone of this SHA256 Object

engineReset

public void engineReset()

SPI: Resets this SHA256 message digest object for being supplied with new data.

This method is called by engineDigest after the actual hash computation has been finished to automatically reset the message digest object for being supplied with new data for starting a new hash computation.
