4.6-4.8

The part about how different people cracked a DES password through distributed, and then custom aproaches was interesting. I thought that the EFF project was interesting since they managed to produce a machine which could crack DES in a matter of days on a relatively small budget. Additionally, it made me wonder how fast someone could crack DES encryption today with custom hardware. On part of it I felt like the book was incorrect in stating that adding salt to the UNIX one way password function made it so that a chip would have to try all 4096 possibilites. It seems like the people who wrote the book have never used an FPGA since it would be easy to just have an input for the salt and then switch the bits based on the salt.
