A Caesar cipher', or shift cipher is a primitive form of encryption named after Julius Caesar who used the encryption algorithm in his letters. The algorithm works by shifting every letter in the plaintext forward in the alphabet a specific number of values to form the ciphertext. For example, using a Caesar cipher of 1, A becomes B, B becomes C, C becomes D, and so forth until you get to Z, which rolls back to the beginning of the alphabet to become A. The cipher is With only minor variations, the algorithm can be adjusted to work with any alphabet for any language.

This algorithm can also be referred to ROT13, which is a specific
