Create an implementation of the rotational cipher, also sometimes called the Caesar cipher.
The Caesar cipher is a simple shift cipher that relies on transposing all the letters in the alphabet using an integer key between
Using a key of
26 will always yield the same output due to modular arithmetic.
The letter is shifted for as many values as the value of the key.
The general notation for rotational ciphers is
ROT + <key>.
The most commonly used rotational cipher is
ROT13 on the Latin alphabet would be as follows:
Plain: abcdefghijklmnopqrstuvwxyz Cipher: nopqrstuvwxyzabcdefghijklm
It is stronger than the Atbash cipher because it has 27 possible keys, and 25 usable keys.
Ciphertext is written out in the same formatting as the input including spaces and punctuation.
