Caesar Cipher

A PHP Port of Rob Spectre's Python Caesar Cipher library. Encode, decode and crack messages with Caesar Shift Cipher.

Installation

You can install this library using composer

Usage

Encoding a message with an offset:

$cipher = new CaesarCipher();
$message = "Brooklyn";
$cipher->encode($message,5);

Decoding a ciphertext with an offset:

$cipher = new CaesarCipher();
$message = "Uxjmjp";
$cipher->decode($message,5);

Cracking a ciphertext without knowing the offset:

$cipher = new CaesarCipher();
$cipher_text = "Bj qfhp ymj rtynts yt rtaj yt ymj sjb gjfy!";
$crack_text = $cipher->crack($cipher_text);
