Cipher Challenge
A Matter of Pairs
Introduction
Francis Bacon’s biliteral cipher conceals one message inside another by assigning every carrier letter to class A or B. Each group of five carrier letters represents one plaintext letter, and a carrier letter keeps the same class wherever it appears. The word BACON occurs somewhere in the plaintext.
