A hash is an object used to calculate a checksum of a string of information.
Methods:
update() -- updates the current digest with an additional string
digest() -- return the current digest value
hexdigest() -- return the current digest as a string of hexadecimal digits
copy() -- return a copy of the current hash object
Attributes:
name -- the hash algorithm being used by this object
digest_size -- number of bytes in this hashes output
