Caesar Cipher
Encrypt and decrypt text using the Caesar cipher with a configurable shift value (1-25). Supports both encoding and decoding modes.
How to Use Caesar Cipher
The Caesar Cipher tool lets you encrypt and decrypt text using one of the oldest known ciphers. Enter your text, choose a shift value (1-25), and select encrypt or decrypt mode. Each letter is shifted by the specified number of positions in the alphabet. Non-alphabetic characters are preserved unchanged. This tool is great for learning about classical cryptography, creating simple encoded messages, solving cipher puzzles, or teaching the fundamentals of encryption. All processing happens in your browser.
