Create a password protected zip

[XPOL555]

The ->setPassword() method is not setting the password for the archive you are making; it's just setting the password to use to extract files when reading a zip archive.

As noted in this comment https://www.php.net/manual/en/ziparchive.setpassword.php#122465 the correct way to create a password protected zip file is to use ->setEncryptionName('test.txt', ZipArchive::EM_AES_256, 'passw0rd'); on each file entry.

This is currently not possible on Madzipper because the repository is not giving public access to the ZipArchive instance.

i have created this pr #17 to add the methods to let user set password by name or by index (just reflecting the ZipArchive methods).

My current solution was to extend completely MadZipper and add a ->makeCustom() methods that let me use a custom repository. The custom Repository has public access to $archive property. So i can do this:

//MadZipperCustom.php

class MadZipperCustom extends MadZipper{

  //other methods here...
  //copy and paste almost any private method and property
 
  public function makeCustom($pathToFile, $type)
      {
          $new = $this->createArchiveFile($pathToFile);
  
          $objectOrName = $type;
          if (is_string($type)) {
              $objectOrName = $type; //this is the main difference, the original make method lets just classes within the Madnest namespace
          }
  
          if (! is_subclass_of($objectOrName, 'Madnest\Madzipper\Repositories\RepositoryInterface')) {
              throw new \InvalidArgumentException("Class for '{$objectOrName}' must implement RepositoryInterface interface");
          }
  
          try {
              if (is_string($objectOrName)) {
                  $this->repository = new $objectOrName($pathToFile, $new);
              } else {
                  $this->repository = $type;
              }
          } catch (Exception $e) {
              throw $e;
          }
  
          $this->filePath = $pathToFile;
  
          return $this;
      }
}

//PasswordProtectedZipRepository.php

class PasswordProtectedZipRepository implements RepositoryInterface {
     /**
     * @var ZipArchive
     */
    public $archive;
    
    //other required methods here...
}

and the final usage:

$zipper = new MadZipperCustom();
$zipper->makeCustom('myzip.zip',PasswordProtectedZipRepository::class);
foreach ($files as $file) {
    $zipper->addString($file->name, $file->content);
    $zipper->getRepository()->archive->setEncryptionName($file->name,\ZipArchive::EM_AES_256,$password);
}
$zipper->close();

i hate this solution alot and ⚠️ i do not reccomend this. That's why i'm here taking sometime to explain the situation and maybe change something on this repository 😄
