Execute steam=Shake256(m,d) with inputs m (character array or byte array of any length as the input stream) and d (number of output bytes desired). The output (stream) will be the number of bytes requested (d) in hexadecimal form. This code can be easily converted to Shake128 by adjusting the constant r=1344 in the SPONGE function. It has been tested on many input streams and provides the expected output streams.
