Hi all, i'm trying to figure out how to run some basic server side code which will hide a private key... I did this before with PHP, but now in DNN I can't figure out how to do anything other than normal HTML... Below is the code I am trying to replicate (with generic keys put in obviously)


function get_signed_player($videokey,$playerkey) {
$path = "players/".$videokey."-".$playerkey.".js";
$expires = time() + 3600;
$secret = "Ksi99h9938sjKfha9JaheEMp";
$signature = md5($path.':'.$expires.':'.$secret);
$url = 'http://content.mysite.com/'.$path.'?exp='.$expires.'&sig='.$signature;
return $url;
};

echo "Watch this cool video:";
echo "script type='text/javascript' src='".get_signed_player('nPrip99l','ALJ9XQCI')."'>"; ?> "

Where are you trying to put this?

Normally, something like this would be part of the code behind in a module.

I'm trying to put this on any page (i.e. in an HTML module)

So, to explain, I am playing video on my website. The video is hosted somewhere else and the "embeded link" needs to be authenticated (and has a time component, so it eventually expires)...

In order to properly embed the video, I have to put the link on my page which automatically generates a new link with a new time expiration. Problem is that if I do all this through normal HTML, anyone can see my "secret" keys and could embed the video on their website.

Ideally I need to do this calculation server side and then have it generate a completed link (hence the PHP script above)

I just need some way to generate this link server side and then spit out the HTML code.. Is there any way to just use a normal PHP or ASP style code to do this? Seems like it would be relatively simple, no?

You can probably do this by using an IFrame to show an asp page.

It would be better, though, to do this in a simple module.  Essentially, you can convert your asp script to asp.net code in a module.  Modules that are basically code and don't require database access or settings are a relative snap to create.

You also can do this with OWS or DotNetMushroom.

K, silly question, but I've got no idea how to create a module. Any places I can find instructions for how to do this (given the fact that I'm not accessing the database at all I'm guessing this would be relatively simple...)

This example is a good one.  You put your "script" code (converted to vb or c#)  in the codebehind file for view.ascx. 

Ask if you need more pointers or help.

OK, I think I can do that, but I don't use VB a whole lot...

Could you help me translate the above PHP code into VB, making sure I have one input for "PATH"

(essentially I need a module where I could drop in the "path" to the specific video, and then it would do all the above calculations server side, and spit out the proper javascript / URL and thus display the video)

(Here is the full script example from the other website, except that I spelled out the word "plus" because I couldn't figure out how to get the symbol to show up here..:

* This PHP function will generate a signed URL. Parameters:
*
* $path - The path of the video or player you want to sign, e.g. "videos/KsoieJsu-123.mp4"
* Note this excludes the domain and excludes the trailing slash.
* $secret - The API secret of your account, e.g. "Jau8Ya71hakdpF0A".
* This acts as a shared secret between your server and BOTR.
* $timeout -The time in seconds you want the signed URL to remain valid, e.g. "3600".
* Typical timeouts are between a minute and a few hours. Default is "3600".
* Make sure the time on your server is set correctly, or URLs with short timeouts will fail!
* $domain - The masked domain name you want to use for signing the content, e.g. "video.mysite.com".
* Use this if you have setup DNS masking. Defaults to "content.bitsontherun.com".
**/
function get_signed_url($path,$secret,$timeout,$domain) {
if($timeout) {
$expires = time() "plus" $timeout;
} else {
$expires = time() "plus" 3600;
}
$signature = md5($path.':'.$expires.':'.$secret);
if($domain) {
$url = 'http://'.$domain.'/'.$path.'?exp='.$expires.'&sig='.$signature;
} else {
$url = 'http://content.mydomain.com/'.$path.'?exp='.$expires.'&sig='.$signature;
}
return $url;
};

I did a quick web search and found some sites that claim to be able to translate php to vb. 

Ah yes, didn't even think of that. Ok, thank you!
