Section 2.3, September 14

1. The hardest part to understand in this article was deciphering the key length used in the cipher. It is actually a really interesting analysis of the language, in the way that their is a higher chance of letters occurring the same with the shiften cipher. It does show me that to come up with breaks for older ciphers a solid knowledge of the language was needed.

2. The most interesting part for me was the cipher its self. I think it is really interesting how traditionally people took known ciphers and modified them so they make it harder to break. It is interesting how much harder it is to break these slightly shifted codes. It is also interesting because it represents a key being added to a known cipher who key before was just a pairing of letters to other letters.
