The presentation today was very interesting. I really loved to hear the different ways that things had been coded in the past. The most interesting one for me was the final cipher she showed us. It was interesting because it reminds me quite a bit of the way that modern symetric encryption works. You could even do a one-time pad with it if you had a long enough key.
It was also really interesting to see the other way they hid messages besides codes. It was a good stody of the history of codes, back when the key was not knowing the algorithm rather than not knowing the key.
Nothing really stood out as hard to understand, but that was just because the presenter did a great job.
