Section 2.5 - 2.8, September 16

1. The hardest part of this reading was in understanding how to break the Hill algorithm. Once again like the rest of the chapter it was hard, it was just the hardest of what their was. I was interesting to see how easy it was to find a working key matrix. I didn't notice that we need to first check the determinate, but it was easy after that.

2. The most interesting part was the Sherlock homes section. It was interesting because it is basically a subsitution cipher that goes to a different alphabet. It was also the most interesting because the story that accompinied it. So it was the most mathametically interesting, but certainly the most exciting part in the chapter.
