1. (Difficult) Most of the lecture was very easy to follow. The trickiest code was when she showed us the one dependent on a repeating word, like "milk" or "fifteen", mapped it's letters to a message and then mapped those letters again to other letters. I didn't completely follow all that but if I had more time to study it I'm sure I could get it. Clever idea.

2. (Reflection) I knew about the D&C name substitutions but didn't know about all of the encrypted letters sent from the Congress representatives to Utah. That's very clever some of the codes they sent. Especially when the decoded words were in a completely different letter. My favorite though was that they used the Hawaiian alphabet as a code and of course only Utah had someone who could read it because of missionary work. Yeah missionary work! I feel like BYU would have someone who could understand pretty much any foreign language thrown at us too. :-)
