A [FPDI](https://www.setasign.com/fpdi) 2 compatible and enhanced version of the [FPDF\_Protection](http://www.fpdf.org/en/script/script37.php) script.

This version requires and uses OpenSSL functions instead of Mcrypt or a user land implementation of RC4.

RC4-40bits and RC4-128bits encryption are supported.

Installation with [Composer](https://packagist.org/packages/setasign/fpdi-protection)
-------------------------------------------------------------------------------------

[](#installation-with-composer)

```
{
    "require": {
        "setasign/fpdi-protection": "^2.0"
    }
}
```

Manual Installation
-------------------

[](#manual-installation)

If you do not use composer, just require the autoload.php in the /src folder:

```
require_once('src/autoload.php');
```

If you have a PSR-4 autoloader implemented, just register the src path as follows:

```
$loader = new \Example\Psr4AutoloaderClass;
$loader->register();
$loader->addNamespace('setasign\FpdiProtection', 'path/to/src/');
```

Don't forget to install [FPDI](https://www.setasign.com/fpdi) and [FPDF](http://www.fpdf.org/), too!

Example
-------

[](#example)

This class offers one public method, which allows you to set the protection of the resulting PDF document. All other code is identically to [FPDI](https://www.setasign.com/fpdi) or [FPDF](http://www.fpdf.org/).

If you pass null or an empty string as the owner password the method will create a random owner password. The return value of this method is the owner password.
