Caesar Cipher

The Caesar cipher is one of the simplest and most widely known encryption techniques. It shifts each letter by a fixed number of positions in the alphabet.

Input Text

Shift (0-25)

How it works:

•Each letter in the plaintext is shifted by a fixed number of positions
•For example, with a shift of 3: A→D, B→E, C→F, etc.
•The shift wraps around: X→A, Y→B, Z→C (with shift 3)
•Non-alphabetic characters remain unchanged
