IMPORTANT

Because the project is not Laravel/Lumen, the use of upload, download and encryption features is not documented.

Find functionality by implementing the framework's service containers or create your own solution.

If you want to use this package in a project that is not based on Laravel / Lumen, you need to make the adjustments below

1 - Install dependencies to work correctly.

composer require illuminate/container illuminate/filesystem ramsey/uuid

2 - Prepare the code to launch the Container and FileSystem instance.

<?php

require_once 'vendor/autoload.php';

use Illuminate\Container\Container;
use Illuminate\Filesystem\Filesystem;
use Illuminate\Support\Facades\Facade;

try {
  $app = new Container();
  $app->singleton('app', Container::class);
  $app->singleton('files', Filesystem::class);
  Facade::setFacadeApplication($app);
  
  // Allow the use of Facades, only if necessary
  // $app->withFacades();
} catch (\Throwable $th) {
  // TODO necessary
}

3 - After this parameterization, your project will work normally.

<?php

require_once 'vendor/autoload.php';

use Illuminate\Container\Container;
use Illuminate\Filesystem\Filesystem;
use Illuminate\Support\Facades\Facade;
use LSNepomuceno\LaravelA1PdfSign\ManageCert;

try {
  $app = new Container();
  $app->singleton('app', Container::class);
  $app->singleton('files', fn () => new Filesystem);
  Facade::setFacadeApplication($app);
  
  $cert = new ManageCert;
  $cert->fromPfx('path/to/certificate.pfx', 'password');

  $pdf = new SignaturePdf('path/to/pdf/file.pdf', $cert, SignaturePdf::MODE_RESOURCE) // Use resource mode is default
  $resource = $pdf->signature();
} catch (\Throwable $th) {
  // TODO necessary
}
