About Caesar Cipher
The Caesar cipher is one of the simplest encryption techniques. It works by shifting each letter in the plaintext by a fixed number of positions down or up the alphabet.
Security Note
While Caesar cipher is great for learning about cryptography, it’s not secure for modern encryption needs as it can be easily broken through brute force or frequency analysis.
