WKS-KEYS Guide

[theshakez]

Hi Guys.

Cant seem to find a topic on here just for using WSK-KEYS (although there must be one I'm sure)

So just the process for extracting the key once PSSH & Licence URL have been obtained.

So just need some help on the commands & requirements.

Thx Gaz.

[theshakez]

Hey guys

So I've now got an L3 CDM

I've installed Python 3.9.7, have WSK-KEYS & have downloaded protobuf-3.20.0 (I'm on Win10)

Apparently it should work now is that correct?.. but I've just no clue how it works.

Any help for this noob would be great.

Thx Gaz

copy those files into the "WKS-KEYS\pywidevine\L3\cdm\devices\android_generic" folder, rename the files:
client_id.bin -> device_client_id_blob
private_key.pem -> device_private_key

Add headers from Licence POST to headers.py in python format
Use l3.py and enter the info it asks for

There are many such tutorials on the forum!

Hi piaohua

Thanks for the help.

So I've already renamed the 2 files but still struggling here.

https://files.videohelp.com/u/301511/1.JPG

You guys are all gurus / coders so its like another language to me lol

I've installed Python 3.9.7, have WSK-KEYS & have downloaded protobuf-3.20.0 (but protobuf-3.20.0 is just a folder on my PC do i need to install it or something I wouldn't know how

I typed import base64, requests, sys, xmltodict apparently I need to do that but nothing happens

I just get what's seen in the screenshot when I type l3

Thx Gaz

[piaohua]

you need

Open CMD

pip install requests

pip install xmltodict

pip install protobuf==3.20.3

Prompt to install what is missing

[iamghost]

open and run cmd in wks-keys folder
pip install -r requirements.txt
edit header.py andd header and save it
run l3.py
add pssh and lic url
they will give you keys

[theshakez]

Thx guys but I've failed at the first hurdle as I expected lol.

So I'm obviously doing something wrong here.

Any help would be very grateful, done a bit of googling but this is so new to me I just get more lost lol.

Thx Gaz

....\WKS-KEYS>pip install requests

[piaohua]

don't type py

[theshakez]

Thanks again for the help guys!!..... but I'm still being a tool somehow lol.

Thx Gaz

[piaohua]

try py -m pip install requests

You need to add the path of your pip installation to your PATH system variable.

you can try to uninstall your Python, then go to python.org download the latest version, Check to add environment variables during installation!

[theshakez]

Some progress guys!!

So this did the trick:

py -m pip install requests
py -m pip install xmltodict
py -m pip install protobuf==3.20.3

I downloaded the latest python & made sure it installed pip (something i didn't know) also added add environment variables

I thought i did need to be Python 3.9.7 so that must have been my error.

Now when I run l3.py I get the below.

Am i correct in thinking when I run l3.py it should just ask for PSSH & Lic URL & then it returns.

I've not edited any of the files in WSK-KEYS apart from adding my CDM & renaming them.

Thx Gaz

You haven't installed all necessary modules. Inside the WKS folder there should be a "requirements.txt" file. Just run "pip install -r requirements.txt" and it'll install everything you need. If you don't have a file like that, just create a new one and put these lines in:

requests
xmltodict
google
protobuf==3.19.5
pycryptodomex

[theshakez]

stabbedbybrick Thx mate!!!

Yes I had to create it & now almost there.

So entered PSSH & URL but now get this.

So is there some file I need to edit in WSK-KEYS to get it finally work?

Thx Gaz

[stabbedbybrick]

That error means your headers.py file is empty or formatted wrong. That "headers=headers.headers" part means the script is looking for the headers inside the headers.py file.

They need to be formatted like this(or more specific to whatever service you're getting keys from):

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/111.0',
    'Accept': '*/*',
    'Accept-Language': 'en-US,en;q=0.5',
}

Keep in mind though that WKS as it comes packaged is a very basic script and will not work for all services. If your specific service require additional challenges or parsing, you'll need to learn some Python.

Thank you that has finally worked!
I just got some ITVX stuff.

Again thanks everyone who's helped me, greatly appreciated

Hello all. when adding to the headers.py file i copied the lic url and placed it in curlconverter. then added this to headers.py file:

headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/118.0',
'Accept': '*/*',

}

data = '^\b^\x04'

response = requests.post(
'https://drm.content......../licenseServer/widevine/v1/........./license',
headers=headers,
data=data,
)

but still getting check protobuf error. My question is did i do the header.py correct?

thank you for any help.

[iamghost]

Header.py is

Import requests

headers = {
'Authorization': 'Bearer .........’,
}

[titotrinidad]

Header.py is

Import request

headers = {
'Authorization': 'Bearer .........’,
}

Thank you sir. i appropriate your help

[titotrinidad]

After following your excellent directions i get this error code. I tried playing with it hoping i was just inputting wrong but cant get the error removed.

[iamghost]

import requests

headers = {
'Authorization': 'Bearer' 'ey..........',

After following your excellent directions i get this error code. I tried playing with it hoping i was just inputting wrong but cant get the error removed.

You are missing the apostrophe at the end, this one -> '
See how "Bearer blabla" is not grey?
It should be grey.
Or you copy pasted from ghost, and he used another apostrophe or whatever that character is

’ ≠ '
