About Caesar Cipher
The Caesar cipher is one of the simplest and most widely known encryption techniques. It's a substitution cipher where each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. This tool allows you to both encrypt and decrypt messages using this classic method.
