File MD5 checksum for integrity check on downloads
Proxima
To do this would require a small custom module with a "save_media_file" event listener that would do an md5_file() on the uploaded file - i.e.
function xxCustom_save_media_file_listener($_data, $_user, $_conf, $_args, $event)
{
$_data["{$_args['file_name']}_md5"] = md5_file($_args['saved_file']);
return $_data;
}
Let me know if that helps.
