It's really interesting to interact with problems that don't ever come up in the day job, I'm only part way through set 2 but this has taught me a huge amount already. > People "know" this already, but they don't really know it in their gut, and we think the reason for that is that very few people actually know how to implement the best-known attacks. I agree with them when they say it's important to teach implementations alongside theory. Despite knowing some theory behind cryptography seeing implementations come together is still an eye-opener. I guess it's like the difference between knowing orbital mechanics which is basically high school math and then playing kerbal space program and crashing rockets because while you could derive the functions every time it still takes some practical feel before things "click". Only in this case you also get to break it all down again which is another level of satisfaction.
