1. Install via composer

    ```
    composer require sivin/crypt
    ```
2. Register extension in `config.neon`:

    ```
    extensions:
    	crypt: SiViN\Crypt\DI\CryptExtension
    ```
3. Create or use your key/s:

    ```
    /** @var Crypt */
    private $crypt;

    public function __construct(Crypt $crypt)
    {
    	$this->crypt = $crypt;
    }
    ...
    $keys = $this->crypt->createKeyPair()
    $privateKeyRaw = $keys['privateKeyRaw'];
    $publicKeyRaw = $keys['publicKeyRaw'];
    ```
4. Use your own key or define it in a `config.local.neon`:

    ```
    $crypt->setPublicKey($myPublicKeyForEncrypt);
    $crypt->setPrivateKey($myPrivateKeyForDecrypt);
    //if there is a private key with a password
    $crypt->setPrivateKeyPassword($myPivateKeyPasswordForDecrypt);
    ```

    or in a `config.local.neon`:

    ```
    crypt:
    	publicKeyPath: publicKeyFile.pub #for encrypting
    	privateKeyPath: privateKeyFile.key #for decrypting
    	privateKeyPassword: 'PrivateKeyPassword' #optional
    ```

    > If you only want to encrypt/decrypt, just define the encrypting/decrypting key
5. And finally?:

    ```
    $encryptedStr = $crypt->encryptRijndaelMessage($stringToEncode); //for transport
    $decryptedStr = $crypt->decryptRijndaelMessage($encryptedStr);

    $encryptedStr = $crypt->encryptRsa($stringToEncode);
    $decryptedStr = $crypt->decryptRsa($encryptedStr);

    $encryptedStr = $crypt->encryptRijndael($stringToEncode);
    $decryptedStr = $crypt->decryptRijndael($encryptedStr);
    ```
