🔠 Ciphers

• Caesar Cipher: A simple classical cipher that shifts letters by a fixed number in the alphabet.
• Vigenère Cipher: A key‑based polyalphabetic substitution cipher; exposes encrypt(text, key) and decrypt(cipher, key).

Caesar Cipher Visualizer

Test the Caesar cipher in your browser: Open Visualizer

This tool lets you enter plaintext and a shift value to see the encrypted result instantly.
