Sec 8.3,9.5, due Nov 11th

1. Ok, I'm not going to lie, the secure hash algorithm was a little confusing to me... especially all the new symbols on page 225. I was also confused about how to know the block length that you would divide your message up in to. They had to add like a bunch of 0's and all sorts of stuff to finally get 6 blocks of length 512. So yeah, this section got me.
2. I really liked section 9.5 though. It was clear and I understood it, and it's nice because I've seen all that stuff before. I really liked learning about digital signatures, because not only is it interesting, but it's something that we can all relate to personally. Anyway, good sections for today, just a little confused on 8.3.
