Dec 5, 2016 · The Caesar cipher doesn't just add a value to the character value. What it does is the following (per character in the plaintext):.

Caesar ciphers are encrypted by adding modulo 26 (C = p + key mod 26, where C is ciphertext and p is plaintext) and are decrypted by adding the inverse of the ...
