[Release] Widevine L3 Guesser Extension-Works in 2024 Firefox/Chrome All OS

[FoxRefire]

As I have said many times (and from the content of the error message) the reason you cannot use this extension on some sites is clearly irrelevant as to whether the stream is m3u8 or not.
Once again, this site uses m3u8 for the stream, but the extension works fine.
https://online.familyclub.jp/s/jno/page/live_player_test

The m3u8 stream website you are trying to use "just happens" to use licence wrapping and the scheme is not supported by the extension.

Of course, conversely, even MPD stream websites are not available if the License wrapping scheme is not supported by the extension.
Example:https://www.vdocipher.com/video-security/

Again, I will not respond to a support request for a particular website if there is no scheme submission. (Rule 2)

> I just trying get key from bitmovin webpage, but key wasn't found
Did you select ”https://cwip-shaka-proxy.appspot.com/no_auth” as License URL and ”CommonWV” as Challenge scheme?
Also, did you follow install instruction at README.md properly?

If the above still does not resolve the issue, go to the Network tab in Devtool and check if the response from the license server is normal.

Good morning,
I tried to modify the inject.js code to detect pssh code in simplier mode. with M6Replay it works very well but I can't do it with MYTF1 (see photo)

M6Replay :

[Attachment 78588 - Click to enlarge]

MYTF1:

[Attachment 78589 - Click to enlarge]

my code Get Pssh:

function GetPssh(buffer) {
	var binary = '';
    var bytes = new Uint8Array( buffer );
    var len = bytes.byteLength;
    for (var i = 0; i < len; i++) {
        binary += String.fromCharCode( bytes[ i ] );}
    return window.btoa( binary );
}

...etc
document.dispatchEvent(new CustomEvent('pssh', {detail: GetPssh(initData)}));

Anyway, from looking at your code, it seems that you are breaking the ability to parse PSSH from long init data.

const toHexString = bytes => bytes.reduce((str, byte) => str + byte.toString(16).padStart(2, '0'), '');

great job, if I can give you a function for a future since you have intergrated saving in json of the pssh and key also make a simple file as a cache

Good morning,

I would like to know how to automatically display the link https//widevine...etc in the text license?

if(psshs.length==1){
        document.getElementById('pssh').value=psshs[0];
		document.getElementById('license').value=requests['widevine']; <= show the link which has the word widevine?
        }

Hello, Foxfire, thank you for the good work, would it be possible to add "manifest url" to the automatic detection code, just like in the photo?

[Spectrumhsm]

Great work FoxRefire. Thanks!

With recent many browser extensions doing all the work to get the keys, the use of scripts to get the keys is taking a back seat.

We have entered a sweet spot.

Happy downloading!

Don't forget sharing is caring.

[kingkong0]

I wanted to share with you that today they published decrypting the code for this, which detects url and prints mpd as well. The purpose was to take some of the code and bring it into this

Can anyone here help me implementing the following process into extension?
1.Send message from Popup Script to Content Script with required arguments
2.Execute fetch on Content Script and return result to Popup
3.Await for the content script side to finish processing and receive the result on the pop-up side


Background:
I am currently attempting to add a RedBee's scheme(Channel4) support but this license server requires that the Origin header be identical to the original.
However, when a direct fetch request is made from the pop-up side, the hostname of the extension is used as the Origin header, even though the original Origin is specified, which is obtained by monitoring requests.

[Attachment 78640 - Click to enlarge]
This is because the Origin header is defined as a “Forbidden header name,” and requests made by web browsers usually cannot be set to anything arbitrary.
https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name
However, if you make a fetch request from a content script that runs as “content in a website,” you can send the request with the original Origin applied.
The python scheme file itself is already complete, and I have successfully obtained a license by manually changing the “message” portion of the request body to an arbitrary challenge in the Devtool.

[Attachment 78641 - Click to enlarge]
Therefore, as long as this CORS problem can be solved, the RedBee scheme can be made to work.
My current attempts can be found on the features/RedBee branch of Github.(If you are noob, don't use it. not working for now)
