Installation
------------

[](#installation)

You can install this library using composer

```
composer require caesarcipher/caesarcipher
```

Usage
-----

[](#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);
```

[kunstmaan/utilities-bundle

The KunstmaanUtilitiesBundle makes your life easier by providing a couple of small but usefull helper services you can use and re-use in your applications. We already implemented an easy to use cipher service and a shell helper service for you but feel free to send in a pull request with your additions. The shell helper allows you to run apps in the background, see if a process is running and has a method to kill a running process. The cipher service allow you to encode and decode strings using the Rijndael 256 cipher
