  my $drm = OMA::Download::DRM->new(
      'content-type' => 'image/gif',                            # Content MIME type
      'data'         => \$data,                                 # GIF image binary data reference
  );
  print "Content-type: ".$drm->mime."\n\n";                     # Appropriate MIME type
  print $drm->fw_lock();                                        # Forward lock

combined

Combined delivery

  my $drm = OMA::Download::DRM->new(
      'content-type' => 'image/gif',                            # Content MIME type
      'data'         => \$data,                                 # GIF image binary data reference
      'domain'       => 'example.com'
  );
  print "Content-type: ".$drm->mime."\n\n";                     # Appropriate MIME type
  print $drm->combined($permission, %constraint);               # Combined delivery. See OMA::Download::DRM::REL.

separate_content

Separate delivery. Content encryption and packing.

  my $drm = OMA::Download::DRM->new(
      'content-type' => 'image/gif',                            # Content MIME type
      'data'         => \$data,                                 # GIF image binary data reference
      'domain'       => 'example.com',
      'key'          => '128bit ascii key'
  );
  print "Content-type: ".$drm->mime."\n";                       # Appropriate MIME type
  print "X-Oma-Drm-Separate-Delivery: 12\n";                    # The terminal expects WAP push 12 seconds later
  print $drm->separate_content($rights_issuer, $content_name);  # Encrypted content

You then need to send the rights object separately

separate_rights

Separate delivery. Rights object packing.

  my $rights = $drm->separate_rights($permission, %constraint)  # you have to send this rights object via WAP Push.
