Как сделать file download по паролю самым простым способом?

<?
if($pass1=='12345'){
 
Header('Content-type: application/ppt; name=file.ppt');
Header('Content-Transfer-Encoding: base64');
$filename = 'asdf.ppt';
$fd = fopen( $filename, 'r' );
$contents = fread( $fd, filesize( $filename ) );
fclose( $fd );
echo $contents;
}
?>

<?php
 
if ($pass1 == "12345") {
    $file = 'any_file.ext';
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
} else {
echo "Пароль не подошол";
}
?>
