What is Bacon?
Bacon's cipher (1605) represents each letter with a unique pattern of five binary symbols, classically rendered as a/A and b/B so the message can hide inside innocuous-looking text.
How it works
Each letter maps to its five-letter A/B pattern (I/J and U/V share patterns, as in the classic 24-letter version). Decoding accepts any spacing and validates the groups.
