i’m a little confused on how the s-boxes work; they don’t really make sense to me. i usually get confused when we start talking about bits, because i’m not sure i know exactly what that means. i know i saw this a lot, but i usually don’t really understand this stuff until i go to class or do examples of it.
something that struck me was that a long time ago, the DES was resistant to differential cryptanalysis. i take that to mean that it was relatively unbreakable. but now it’s becoming outdated, which i take to mean that it’s becoming breakable. i just think it’s interesting that we are now able to break codes we haven’t been able to in the past!
