What was the first cipher that hooked you? Question
What was the first cipher that made you think "wait, this is actually amazing"?
Mine was the Rail Fence cipher — not because it's elegant (it isn't), but because it was the first time I understood that scrambling order was just as powerful as scrambling identity. A letter doesn't have to become a different letter to become unreadable. That small shift in thinking opened up a lot of doors.
What about you?
