The Caesarian Cipher is an encryption method where you shift each character based on the given key value (Integer i.e. all Natural Numbers, 0, and Negative numbers). Let's walk through a long-form example of this shifting method then when we go to encrypt, we can scale down the explanation for this step.
As you can see this cipher is fairly basic as it is a linear mapping of the letters based off a shift value. However, the caesar cipher is a great introductory cipher to get us thinking about security and how we can use it to keep our data safe. Now let's go encrypt something...
