AI overview
A Caesar cipher is a simple encryption technique that shifts each letter in a message by a fixed number of positions in the alphabet, making the text unreadable without knowing the shift amount. It matters as a foundational example in cryptography that illustrates basic principles of how information can be scrambled and unscrambled, though it's too simple to provide real security by modern standards.
