Blog due Friday September 28

Which topics and ideas do you think are the most important out of those we have studied?
Conceptually, I think the most important are DES, affine and vigenere ciphers, and possibly Hill ciphers

What kinds of questions do you expect to see on the exam?
Ones similar to those on the homework. I at least hope to have the formulas given for me for stuff like block ciphers though. I could memorize but at least it would be nice to know which encryption styles we needed to have memorized before the test.

What do you need to work on understanding better before the exam?
Probably Hill ciphers. If there will be any proofs on the test, definitely those:)
