About the Caesar Cipher
The Caesar cipher is one of the earliest known and simplest methods of encryption. It's a type of substitution cipher where each letter in the plaintext is 'shifted' a certain number of places down the alphabet. For example, with a shift of 3, 'A' would become 'D', 'B' would become 'E', and so on.
