WebSubstitution cipher decoder. This online calculator tries to decode substitution cipher without knowing the key. It uses genetic algorithm over text fitness function to break the encoded text. Note that you may need to run it several times to find completely accurate solution. The calculator logic is explained below the calculator.

WebThe Caesar cipher (or Caesar code) is a monoalphabetic substitution cipher, where each letter is replaced by another letter located a little further in the alphabet (therefore shifted but always the same for given cipher message). The shift distance is chosen by a number called the offset, which can be right (A to B) or left (B to A).
