4.1, 4.2, and 4.4, due September 17th

1.  The reading was great. I really liked reading about the DES and was fascinated by the amount of encryption and how many layers there are. I guess that helps in a system like DES because it's not a group. I'm also excited to see the more complex cryptosystems.

2. I didn't understand all the technical details of how to do everything. I understood the left-right shift and iteration of the L's and R's but don't see the whole picture very well.
