Guest Lecture, due on September 11

Difficult: 

     I think the most difficult part would be understanding how people didn't break these codes more easily. A lot of the old ways to encode were fairly simple and it seems today would easily have been solved. I suppose it is a pain to have to try and figure out some of the substitution ciphers but still  be possible. I suppose it seems that if someone really wanted to break the cipher they could have.

Reflective: 

   I think it is really interesting how some people wanted to use codes but some did not. Today, I think we are much more likely to want to do cipher things because we care much more about security. In the past they also just had less things they would need to encode. Today we have much greater access to private documents and with more access we need better security and so we want to encode things.
