Question:

Message digests are reasonably fast, but here's a much faster function to compute. Take your message, divide it into 128-bit chunks, and XOR all the chunks together to get a 128-bit result. Finally, do the standard message digest on the result (which is only 128 bits). Is this a good message digest function? Why or why not? You must clearly state your reason, simply giving a yes or no will not earn any credit.

Notice: the operation stated in this question is different form what we have discussed in class when we talked about Hash.
