big clap to this amazing work.
Thanks for develeping this extension, I really appreciate your work! I wish I could donate to you in some way.
I'd also like to donate. This is amazing...
Hello, How to get the key? am getting of 512 count of character(like 300cfc303fc33cc03cfc033f30f00cc3f0c3f.......) only in console chrome.
should i use chrome 88? Thank you for your work

Hello how to get key am getting 512 character usually 32 character only the key would be ! Help me please
should i use chrome 88?
I am using Chrome 89. Any chrome from 89 and above should work for now (until key is changed again). Many chrome-based browser should also work.

You should probably make a separate issue for that... As readme states, you should wait. Right now, it, to my shame, guesses (brute forces) input encoding before decoding it, which is a slow process. It should output progress every ~32 bits for about 10-15 minutes before outputting the key. "300cfc303cf" corresponds to all-zero guess.

Thank you! I do consider work to be failure though... I do have this Bitcoin address lying around? 1N12PaTwaULMLJjmQdggerBYRzcJ6kQCx3
brute forces
ya i got key after nearly 22min ! Nice Man but make it fix !

I can try, but no promises? If somebody knows how to make a lookup table for that, that would be nice. It is possible in theory, but I could not find a reasonably-sized table.
(until key is changed again).
Wait a minute, what key? If you have the new key, shouldn't Tommer's extension work?
Hope this tool can be valid in lifetime, and not to be fix by google or provider of website!
@Satsuoni Do you have playerduo or paypal payment gate ? I want to donate for you to support, I have find many ways to get key to decrypt video but still not work. Now I see your tool and I very interesting about that, I can get many key and can get many videos! Thanks for your tool!

I don't have the whole key. If I did, old extension would have worked (with key replaced). I have a whitebox from dll in wasm (and source code for it). Whitebox is now quite a bit more complex, as far as I can tell, at least the input part of it.

I don't have conventional payment gates, sorry.

Given that google only has to hit "generate random", compile and distribute new binary... Unlikely. Maybe a few months if we are lucky.
I join the thanks above. This is a really great job! Thanks
There is now a copy of l3 guesser that works offline much faster, around 5 minutes. https://github.com/xhlove/WVGuesser Of course it wouldn't be possible without the Satsuoni's work. :)

I tried a different approach, it seems a bit faster. Please check it out. There might be a slight probability that it'll fail for any given encrypted key... I think?

WOrks WIll Super ! Till got correct Keys ! Hats off for your work !!!!!! Time Takes .90sec!
instant!
Great Work !
Great Work !
Can You too Try to fix yours!?

It's not necessary now.
great work to both xhlove and Satsuoni.
xhlove yours have a really good thing that is the log of the wvk in a txt, i was using it to save the keys to dl the video in another moment, was a really cool idea.
Let's see how long this one will last.
Thanks for the quick update! May I ask, are you still gonna maintain your work if either Google may notice this repo or widevine do some patches by any chance?
Satsuoni, can you make it work with Shaka?

I'll try to keep current version available, but I'll probably not modify it after I finish writing Readme. Hopefully that, along with Tomer8007's writeup will provide enough info for other people to pick it up after Widevine updates key again.
Originally, this project was to be a personal exercise (with some public benefits as side effect), and confidence booster. It failed the latter goal, but at least I managed to make it barely functional. Working on it for much longer is probably bad for my mental health, sorry.
Satsuoni, can you make it work with Shaka?
Probably not. I am not sure what you expect it to do? If you have license, you can still play video, can you not?

nice! it giving the key almost instantly!
It failed the latter goal
What?! It failed to boost your confidence!? But how!? You did all of this amazing work, you weren't really optimistic about making it faster, and after a day or two you made it to give keys instantly!
You are a genius! How can this endeavour not boost your confidence!?
Satsuoni, can you make it work with Shaka?
Seems like Shaka player overrides hooks somehow. I cannot spend any more time on it tonight. In case of emergency, it should be possible to set breakpoint in onSessionMessage_ and manually feed data into extension, I guess?

Human mind is a strange thing. But to simplify: I wanted to extract RSA key. I managed to extract half of RSA key and whitebox that calculates the other half, which I still have little idea how it work, and it took much longer than expected, so...
Rest can work wonders on that 'strange thing'. Maybe in the future you'll succeed :) What one feels and thinks at one time can be different at another time in the future.
I test the latest version on "https://bitmovin.com/demos/drm". Doesn't generate the key, I only see this message inside the chrome console: "Can't verify license request signature; either the platform is wrong or the key has changed!"
@phanluchoaofficial20 Try https://github.com/nilaoda/widevine-l3-guesser/tree/modified press on the extension icon to get the keys.
@cavalia88 Not sure if this is the reason you got the message "Can't verify license request signature; either the platform is wrong or the key has changed!", but this extension will work only on Windows 64bit, Windows 32bit is not supported.
I need key to decrypt video on galaxyplay.vn, not a base64 or HEX

@phanluchoaofficial20 - I tried using the modified link you mentioned. No luck. It shows "Current tab found no keys"
I'm using Windows 64bit and Google Chrome v92. Not sure what is the problem.

Because of that page we must have a account with have registered package like galaxyplay.vn I have mentioned
@phanluchoaofficial20 What is in HEX is the key that we get using @Satsuoni extension, you could upload your modified version of the extension that will help @Satsuoni to modify his. You could make a fork from @Satsuoni repository then make a pull request that @Satsuoni could merge in his repository if he saw it as a good idea.
@cavalia88 Try using a portable Google Chrome, install only @Satsuoni extension on it.

That site is the only one with DRM I can check at the moment, and it works? So I am not sure what is wrong in your case. Which Widevine version do you have?
Hello @Satsuoni ,
Can you update your extension again how to display key by popup instead of opening F12 like this: This will be avoid google fix and avoid the website want to get key block open F12!
Thanks!
I don't like alert popups, so I am not going to change to that. That said, I think there is a fork that does something similar to what you want, or you can just replace console.log with alert in content_key_decryption.js

I finally managed to get the extension to work by using Chrome v89 (64 bit).
It does not work on v92. Not sure whether it works with V90 or v91.
You may need to tinker with the code to allow it to work on the latest v92.

Umm?
Please tell me your Widevine version

I downloaded the latest portable version of Chrome v92 and it now working well.
Not sure what was the cause of the earlier problems. Could have been some conflict with other existing extensions.
Many thanks for your assistance and this wonderful app/code.

Sure, no problem... Just in case, a few notes (in general, not to anybody in particular):
@Satsuoni How could I modify the the extension to run on Windows 32bit? I have an old CPU which can run Windows 7 64bit and Windows 10 32bit. I have both of the operating systems installed on my PC, but Windows 10 is my main operating system now.

No idea, really. What kind of error does it give? If it says "either the platform is wrong or the key has changed", then probably they use different key for 32-bit systems, and you would need to extract it separately.
Have you tried z3 to help your reverse engineering works, maybe it can help you.
Sometimes, if you have the intermediate variables, then it can calculate the origin data.

No, did not try it... Pretty sure it'll run out of memory, though. Do wish I thought about that before, but I don't have much more time to dedicate to this problem anymore. (Cannot read Chinese without Google translate, either XD).
@Satsuoni This is the error message, could this problem caused by wasm_gsr.wasm being built on a 64bit operating system?
You, Satsuoni sir, are a true hero! How can we donate? You did an INCREDIBLE JOB, I just can't believe this. Please keep up the good work!
