About Caesar Cipher
The Caesar Cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.
For example, with a shift of 3, 'A' would be replaced by 'D', 'B' would become 'E', and so on. The method is named after Julius Caesar, who used it in his private correspondence.
