Answer:Caesar cipher is one of the earliest known and simplest ciphers. It is a type of substitution cipher in which each letter in the plaintext is 'shifted' a certain number of places down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on.

A Caesar Cipher is a basic encryption type.

Explanation:

Its implementation is very easy and straightforward. It uses a one-to-one of characters in a character set. The input needed is the plain-text message and the encryption number.

For example, using the character set A-Z, encrypting the text CS IS COOL using the key of 3 generates FV LV FRRO. What has been done here is to take each character in the plain-text message and move it by "encryption number steps" in the character set.
