http://xx.xx.xx.:8081/vod/sample.mp4/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9NS80LzIwMTIgODozMzowNSBBTSZoYXNoX3ZhbHVlPXE3MjN6aEVmdGFUOUJoWjBQTmw1TVE9PSZ2YWxpZG1pbnV0ZXM9MjA2

i have see the toutrial here https://blog.wmspanel.com/2013/11/nimble-streamer-protect-hotlinking-domain-lock.html

i dont know where to put this code and how to deal with it

<?php
$today = gmdate("n/j/Y g:i:s A");
$initial_url = "http://stream.company.com:8081/vod/sample.mp4/playlist.m3u8";
$ip = $_SERVER['REMOTE_ADDR'];
$key = "defaultpassword"; //this is also set up in WMSPanel rule
$validminutes = 20;

$str2hash = $ip . $key . $today . $validminutes;
$md5raw = md5($str2hash, true);
$base64hash = base64_encode($md5raw);
$urlsignature = "server_time=" . $today ."&hash_value=" . $base64hash. "&validminutes=$validminutes";
$base64urlsignature = base64_encode($urlsignature);

$signedurlwithvalidinterval = "$initial_url?wmsAuthSign=$base64urlsignature";
?>

i use videojs to stream my m3u8 ive made a rule to protect against progressive download but when i play the stream i get a video.ts file grapped by idman this is another problem i want to resolve it

This code should be on your test player page, and you should replace stream URL with signed version like this:
<video src="<?=$signedurlwithvalidinterval?>">
Player page should be handled by PHP - in some cases it enouth to give .php extension, but it depend on server config.

Thank You Bro FOr Your reply But IStill Get NOthing i see The player But its doesnt play anything this is the code i make inse a file.php
please correct me

<?php
$today = gmdate("n/j/Y g:i:s A");

$ip = $_SERVER['REMOTE_ADDR'];
$key = "19866687"; //this is also set up in WMSPanel rule
$validminutes = 20;

$str2hash = $ip . $key . $today . $validminutes;
$md5raw = md5($str2hash, true);
$base64hash = base64_encode($md5raw);
$urlsignature = "server_time=" . $today ."&hash_value=" . $base64hash. "&validminutes=$validminutes";
$base64urlsignature = base64_encode($urlsignature);

$signedurlwithvalidinterval = "$initial_url?wmsAuthSign=$base64urlsignature";
?>
