MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$Vector_of_FileHash = $MadelineProto->upload->getCdnFileHashes(['file_token' => 'bytes', 'offset' => int, ]);

Or, if you're into Lua:

Vector_of_FileHash = upload.getCdnFileHashes({file_token='bytes', offset=int, })
