   Framework adapted from Dinu Gherman's MD5 implementation by
   J. Hallén and L. Creighton. SHA-1 implementation based directly on
   the text of the NIST standard FIPS PUB 180-1.

        Update the md5 object with the string arg. Repeated calls
        are equivalent to a single call with the concatenation of all
        the arguments, i.e. m.update(a); m.update(b) is equivalent
        to m.update(a+b).

        The hash is immediately calculated for all full blocks. The final
        calculation is made in digest(). It will calculate 1-2 blocks,
        depending on how much padding we have to add. This allows us to
        keep an intermediate value for the hash, so that we only need to
        make minimal recalculation if we call update() to add more data
        to the hashed string.
