The **SimpleCryptographicService** class contains method to encrypt/decrypt phrases with symmetric encryption. With the usage of [OpenSSL](https://www.php.net/manual/en/intro.openssl.php) each encoding of the same phrase results in a different encoded string.

Quick example usage:

```
$cryptographicService = new SimpleCryptographicService('$ecr3t');

$encryptedString1 = $cryptographicService->encrypt('Hello world!');  // some encrypted string, i.e. 'ABCDEFG'
echo $cryptographicService->decrypt($encryptedString1);              // outputs 'Hello world!'

$encryptedString2 = $cryptographicService->encrypt('Hello world!');  // some encrypted string, i.e. 'HIJKLMNOP'
echo $cryptographicService->decrypt($encryptedString2);              // outputs 'Hello world!'
```

This library can be used easily in Symfony projects but also in non-Symfony projects.

Requirements
------------

[](#requirements)

The usage of [**PHP ≥ v7.4**](https://www.php.net/manual/en/migration74.php)and [**Symfony ≥ 5**](https://symfony.com/doc/5.0/setup.html) is recommended.

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

[](#installation)

Please install via [composer](https://getcomposer.org/).

```
composer require assistenzde/simple-cryptographic-bundle
```

The bundle will be automatically added to your `bundles.yaml` configuration.

Symfony Configuration
---------------------

[](#symfony-configuration)

By default the bundle depends on the `APP_SECRET` environment variable and uses the `aes-256-ctr` cipher method. If you want to use a custom cipher key **OR** a customer cipher method create the `config/packates/simple-cryptographic-bundle.yaml` configuration file and set the related values.

**simple-cryptographic-bundle.yaml**:

```
simple-cryptographic-bundle.yaml:
  # set a custom cipher key or comment out to use the default value
  # default is %kernel.secret% (which contains the APP_SECRET value)
  key: My-cu5t0m-c1ph3r-k3y
  # set a custom cipher method or comment out to use the default value
  # default is aes-256-ctr
  cipher: camellia-128-ofb
```

Usage
-----

[](#usage)

Use dependency injection to access the cryptographic service.
