Sorry for my bad English.

I using Wowza Stream Engine and I Enable Outgoing security with SecurityToken Version 2.

My Application using C# on server to generate PLay URL

I do Step by step in this article: https://www.wowza.com/docs/how-to-protect-streaming-using-securetoken-in-wowza-streaming-engine

These is my Configuration:

Server Root Url: http://192.168.1.107:1935

VOD ApplicationName: vod

Share Secret: aaaa

Query Prefix: imv

FilePath: sample.mp4

Option: Include client IP address in hash generation Is On

Client IP: 192.168.1.107

And String for hash Generated: vod/sample.mp4?192.168.1.107&aaaa

I Use SHA256 for Encryption.

And this is may Result:[PHP]http://192.168.1.107:1935/vod/sample.mp4/playlist.m3u8?imvhash=94a7ad9755e8de92cfc68c69afc48ae02f1142fa9f5cd8b1fed2f5792d6d0c41[/PHP]

I try to open this URL in VLC Player. But it not working for me.

Any help, please.

Any help?

Hi,

The calculated hash you are presenting here does not look like a URL-safe Base64 encoded string.

You should also Base64 encode the hashed string and replace the ‘+’ character with the ‘-’ character and the ‘/’ character with the ‘_’ character.

hash

(Required) The hash generated at the client as a URL-safe Base64-encoded string. URL-safe Base64 encoding replaces the ‘+’ character with the ‘-’ character and the ‘/’ character with the ‘_’ character.

Example: wowzatokenhash=VSNlS5S2Na5KxwwiVLXIcHwC90CF2lHdmCm9v_8Bh0o=

In PHP you can use something similar to this:

<?php
$clientIP = null; // provide client IP optionally
// $clientIP = $_SERVER['REMOTE_ADDR'];
$host = "hostname.com"; // your ip/host
$url= "http://".$host.":1935/";
$stream = "live/myStream"; // your stream
$start = time();
$validity = 1000; // validity in seconds
$end = time() + $validity;
$secret = "00secret"; // your secret
$tokenName = "wt";
$params = array("{$tokenName}starttime=".$start, "{$tokenName}endtime=".$end, $secret);
if(!is_null($clientIP)){
        $params[] = $clientIP;
}
sort($params);
$string4Hashing = $stream."?";
foreach($params as $entry){
        $string4Hashing .= $entry."&";
}
$string4Hashing = preg_replace("/(\&)$/","", $string4Hashing);
$hash = hash('sha256', $string4Hashing, true); // generate the hash string
echo $string4Hashing;
echo "<br>";
$base64Hash = strtr(base64_encode($hash), '+/', '-_'); // Base64 encode the hashed string
$playbackURL = $url.$stream."/playlist.m3u8?".$tokenName."starttime=".$start.$tokenName."endtime=".$end.$tokenName."hash=".$base64Hash;
echo $base64Hash;
echo "<br>";
echo $playbackURL;
echo "<br>";
?>

Hi,

If wanted to access files in a sub-folder then be sure to use definst when you construct your URL, for example

protocol://[wowza-address]:1935/[app-name]/_definst_/mp4:[path]/[stream-name]
[/url]
