Bacon's cipher, also known as Bacon's alphabet, is a method of steganography invented by Francis Bacon in the early 17th century. It encodes a message by substituting letters for groups of five binary digits (bits). The key idea is that each letter of the alphabet is represented by a unique combination of five characters, traditionally using the letters "A" and "B," but it can also be adapted to other character sets.
