The Caesar cipher is an encryption technique that was used by Julius Caesar to send secret messages to his allies. It works by shifting the letters in the plaintext message by a certain number of positions, known as the “shift” or “key”. Try decrypting: qnspjins.htr/ns/ougwzjmbnqjw with a shift of 5 😉.

Here is how it works:

1. Choose some text you want to encrypt
2. Choose a shift value between 1-25
3. Choose output as plain text or encoded numbers
4. Enter output and shift value to decrypt later
