Caesar Cipher/ROT 13

The Caesar Cipher or Caesar Shift is a cipher which uses the alphabet in order to encode texts.

CAESAR encoded with a shift of 8 is KIMAIZ so ABCDEFGHIJKLMNOPQRSTUVWXYZ becomes IJKLMNOPQRSTUVWXYZABCDEFGH

ROT13 is the same thing but a fixed shift of 13, this is a trivial cipher to bruteforce because there are only 25 shifts.
