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

[pssh]

1. Update your extension to the latest version
2. Edit in python/after.py file.

# parse license challenge
cdm.parse_license(session_id, licence)

# get keys
keys=""
for key in cdm.get_keys(session_id):
    if key.type=="CONTENT":
        keys+=f"--key {key.kid.hex}:{key.key.hex()}\n"  # close session, disposes of session data
cdm.close(session_id)
keys

Keys will be shown like :

Thank you.

Just a note, if you commenting out the old line (8) and adding new one
do not use TAB, only spaces .....

Using TAB will make it not working ....(At least on Windows 11/Chrome)

#REPLACE
#########################
#keys+=f"{key.kid.hex}:{key.key.hex()}\n"
#########################

#WITH
#########################
keys+=f"--key {key.kid.hex}:{key.key.hex()}\n"

Good morning,

here is how to display the license URL in the text. in the code r.url.includes the name of the license that you use most often me https:\\widevine...etc license

my code in popup.js file :

....etc
drawList(requests.map(r => r['url']),'requestSearch','requestList','license');
	const filteredUrl = requests.reduce((acc, r) => {
    if(r.url.includes('cwip-shaka')) {
        acc.push(r.url);
	}
    return acc;}, []);
    if(psshs.length==1){
        document.getElementById('pssh').value=psshs[0];
    }
	if(filteredUrl.length>=1){
		document.getElementById('license').value=filteredUrl[0];
	}
    });

[Attachment 78642 - Click to enlarge]

the problem comes in the gauss function to get the key.

let vars=`pssh="${document.getElementById('pssh').value}"\n`
    vars+=`licUrl="${requests[userInputs['license']]['url']}"\n`
    vars+=`licHeaders='${requests[userInputs['license']]['headers'].replace(/\\/g, "\\\\")}'\n`

I tried this but it doesn't work.

let vars=`pssh="${document.getElementById('pssh').value}"\n`
    vars+=`licUrl="${document.getElementById('license').value}"\n`
    vars+=`licHeaders='${requests[document.getElementById('license').value]['headers'].replace(/\\/g, "\\\\")}'\n`

Thanks for your effort and sharing this extension. Works well with Binge, where scripts don't play so well.

Hello everyone,

I would like to know how to obtain the key to videos with links that are automatically displayed in the text with : https://bitmovin.com/demos/drm

my code in popup.js file :

drawList(requests.map(r => r['url']),'requestSearch','requestList','license');
	const filteredUrl = requests.reduce((acc, r) => {
    if(r.url.includes('cwip-shaka')) {
        acc.push(r.url);
	}
    return acc;}, []);
    if(psshs.length==1){
        document.getElementById('pssh').value=psshs[0];
    }
	if(filteredUrl.length>=1){
		document.getElementById('license').value=filteredUrl[0];
	}
    });
}

async function guess(){
    let pyodide = await loadPyodide();
    await pyodide.loadPackage(["certifi-2024.2.2-py3-none-any.whl","charset_normalizer-3.3.2-py3-none-any.whl","construct-2.8.8-py2.py3-none-any.whl","idna-3.6-py3-none-any.whl","packaging-23.2-py3-none-any.whl","protobuf-4.24.4-cp312-cp312-emscripten_3_1_52_wasm32.whl","pycryptodome-3.20.0-cp35-abi3-emscripten_3_1_52_wasm32.whl","pymp4-1.4.0-py3-none-any.whl","pyodide_http-0.2.1-py3-none-any.whl","pywidevine-1.8.0-py3-none-any.whl","requests-2.31.0-py3-none-any.whl","urllib3-2.2.1-py3-none-any.whl"].map(e=>"wheels/"+e))
    let vars=`pssh="${document.getElementById('pssh').value}"\n`
	if (document.getElementById('license').value.length==1){
		vars+=`licUrl="${document.getElementById('license').value}"\n`
		vars+=`licHeaders='${[document.getElementById('license').value]['headers'].replace(/\\/g, "\\\\")}'\n`
	} else {
        vars+=`licUrl="${requests[userInputs['license']]['url']}"\n`
        vars+=`licHeaders='${requests[userInputs['license']]['headers'].replace(/\\/g, "\\\\")}'\n`
	}
    let pre=await fetch('python/pre.py').then(res=>res.text())
    let after=await fetch('python/after.py').then(res=>res.text())
    let scheme=await fetch(`python/schemes/${document.getElementById("scheme").value}.py`).then(res=>res.text())
    let result = await pyodide.runPythonAsync([vars, pre, scheme, after].join("\n"));
    document.getElementById('result').value=result;
}

I'm stuck with this code to display the headers code:

vars+=`licHeaders='${[document.getElementById('license').value]['headers'].replace(/\\/g, "\\\\")}'\n`

Do you have a solution to resolve this problem with automatic links?

I made a contribution to the pssh-box-wasm project, which was a great inspiration for the development of the new version of my extension, adding the ability to convert the CDM format.
https://github.com/emarsden/pssh-box-wasm/pull/5

If you need to convert CDM format between WVD <==> Blobs, consider using this tool.
https://emarsden.github.io/pssh-box-wasm/convert/

Happy open source!

i've tried Install add-on from file, then load .zip file from extension panel, but i've this:

I don't intend to implement features related to downloading or decrypting content, such as obtaining mpd links, in the future.
This is because I do not want to put myself at legal risk by my extension.

I bet it doesn't work with Canal Plus, right?

unfortunately i tried it with polish canal plus and no luck, even tho its widevine l3

cdm.parse_license(session_id, licence)

# get keys
keys=""
for key in cdm.get_keys(session_id, "CONTENT"):
  keys+=f"--key {key.kid.hex}:{key.key.hex()}\n"

ohh my good

sure bud now you lose the history lol

read my last edit i have it done fixed

[FoxRefire]

[Opinions wanted]
I'm planning to implement a feature in the extension to block requests to the license server temporarily.
License servers such as VdoCipher need to send a one-time token in the request payload, and once the token is consumed, it becomes unusable.
This feature is intended to work around that problem.
I'm currently considering adding an item like “Block acquisition and reload” to the right-click menu on the web page, which would block requests to the license server at the time of reloading.
Let me know if you have an opinion on a better way.

[WALEED2021]

when i add to firefox which file i choose from directory and thee extention works well on chrome on many sites except “ shahid.net”

[sesamap159]

Good morning,
I would like to know is it possible to retrieve the .mpd link of the video?

oooh yeah thad very good idea

Sure, why not


@sesamap159

Who is that geared towards, as Foxrefire has no intensions of adding it?


With respect to having the keys listed as per N_m3u8DL-RE --key format

Edit in python/after.py file.
# parse license challenge
cdm.parse_license(session_id, licence)


# get keys
keys=""
for key in cdm.get_keys(session_id, "CONTENT"):
keys+=f"--key {key.kid.hex}:{key.key.hex()} "


# close session, disposes of session data
cdm.close(session_id)
keys


and

22222
popup.js


From : KEYS: result.split("\n").slice(0,-1)
To : KEYS: result

[jack_666]

Also, it's a good idea to edit the manifest.json and change the version number, say something like (daymonthyear)


"version": "1.28042024",

[FoxRefire]

[Announcement]

You can now request additional custom license schemes even if you cannot write the code.
https://gist.github.com/FoxRefire/fd606ec29a9bfa1f1bef897e0dc3a231
Follow this guide.

Attention:
Requests are not guaranteed to be added.
I will decide whether or not to add a scheme based on the information I receive, based on technical ease and my mood.
If I request it, you must be willing to confirm if the my code works on requested website.
I do not want to go through the trouble of finding a VPN and registering an account to check the operation on my end.

[sesamap159]

Good evening,
I would like to display the mpd link in the console log but I can't get the .mpd link?

here is the code:

chrome.webRequest.onBeforeRequest.addListener(
 function(details) {
	if (details.method === "GET") {
		if ((url.startsWith("https") && (url.contains(".mpd")))){
			chrome.tabs.query({ active: true, currentWindow: true }, function(tabs) {
				chrome.tabs.sendMessage(tabs[0].id, { action: "MpdUrl", mpd_url: url }, function(response) {console.log(response)});
			});
        }
	}
 }, 
 {urls: ["<all_urls>"]},
 ["requestMDP"]
);

Depends what site you're on - it's not necessarily the case that all sites load .mpd files as a single file over a network request - some make it more difficult.
