Monoalphabetic Cipher in C++ - Sanfoundry

WebJan 17, 2024 · We get a formula for rotating cipher [i] left by key: cipher [i] - 65 brings the ASCII range A .. Z into an integer range 0..25 (cipher [i] - 65 + 26 - key) % 26 rotates that value left by key (subtracts key modulo 26) + 65 to shift the range 0..25 back into ASCII range A .. Z. e.g. given a key of 2, A becomes Y, B becomes Z, C becomes A, etc. 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).
