[Release] WidevineProxy2 Extension; Bypass HMAC, 1-timetokens, Lic wrapping

[Tom Saurus]

Any way of making this work with an older version of FireFox?

If you are on Windows 7 they have extended releases of Firefox at least for now.

I do have the latest available version downloaded and I'm able to install the extension but it's not working. Doesn't give any keys...

what's the name of the website ??

I've tried it on multiple websites and can't get keys from any.

do you have the add-on pinned to the toolbar ??
and have a wvd file ??

I do.

I think the extension only works for people on Windows 10 or above that's why I was asking if there was a way it could be made to work on some older versions...

Have you looked around and thought about perhaps buying a cheap mini pc with Windows 11? They don't use much power and are small and they might be a nice edition to what you have now. They typically have HDMI output and quite often the USB slots are 3.0 which means quite a lot faster transferring of files. On top of that you don't have the 2 TB limit that older PCs have and sometimes you can find 4 and 5 TB hard drives on sale at not much of a higher price than the 2 TB hard drives. Pair them with a wireless keyboard with track pad built in you can make a big screen TV your computer monitor and sit back on the couch and relax with the keyboard some of which come with a few media keys.

Might as well try Linux on existing PC.

That is a good suggestion if he could have both Linux and his current OS and switch between one or the other.

That's still not how the server's backend works

Can you bring it back? It is needed for testing and improving alternative DRM implementations.

Now that I've updated the code to be more secure anyway I'll just post what the server's code looked like:

welp, deleted it when switching servers
this is what I remember:

blocked protocol version VERSION_2_1 because that's what pywidevine uses and Chrome uses VERSION_2_2
blocked unencrypted client IDs
blocked invalid pssh data (different from what's in the mpd)
blocked android requestIds
made sure that the an IP's request flow would happen like this: request html page -> request service certificate -> request license, otherwise block connections to larley.dev/auth (or whatever it was)

openwv got through because it doesn't care whether the widevine device is android or not: https://github.com/tchebb/openwv/blob/main/src/init_data.rs#L55
while pywidevine does: https://github.com/devine-dl/pywidevine/blob/master/pywidevine/cdm.py#L326


Regarding my new site:
Are you able to access it (just try to open https://larley.dev/)?
I've had some issues accessing it on specific networks

The website doesn't work for me.

By the way, is it possible to make custom Widevine/PlayReady license servers and not just proxies, or it requires to have certificate signed by Google/Microsoft? Then also use third-party license servers (like said Bitmovin one) for detecting revoked CDMs. If it is possible to generate a request without having CDM private key.

[larley]

The RSA device private key is used to sign the contents of a license request, you can't just omit it. Same goes for the client id blob.

[pesfacemaker]

Could you have a look at the PM I sent you @larley?

[ginko]

after chrome update 138.0.7204.101 it got disabled and says it was deactivated and will be no more supported.
great

[larley]

works completely fine?

[logipin]

I was able to install and grab keys, along with the cmd.

But when I run the command from WidevineProxy2:

N_m3u8DL-RE "https://varnish07-c05-lax1-dss-vod-dssc-shield.tr.na.prod.dssedge.com/dvt1=exp=1752471039~url=%2Fps01%2Fdisney%2Facddf46 3-2636-4cb3-81bb-77b0c79a2a7f%2F~psid=79f35f91-e00e-4ac4-b450-3636822d3e34~aid=81154747-daeb-422a-a4e9-9be54fcb3846~did=01ce5545-3c79-46f3-9890-2d98c4223342~kid=k01~hmac=e6cf15a1539bc652d36c0376 1c5908bd7fcb39cd8a72daecd0654a17f4df21e2/ps01/disney/acddf463-2636-4cb3-81bb-77b0c79a2a7f/ctr-all-15ae8a39-c5df-4cd2-affd-d50f8888e23b-c906e318-ae12-49f2-9f80-0ad2686ea079.m3u8?fr=30&v=1&hash=c037dfbb0c3b9408e f969596b3037a504d2b012c" -H "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:140.0) Gecko/20100101 Firefox/140.0" -H "Accept: */*" -H "Origin: null" -H "Referer: https://www.disneyplus.com/" -H "DNT: 1" --key <1stkeyhash>:<2ndkeyhash> --use-shaka-packager -M format=mkv

I get this during the process

Failed to get KEY, ignore.: One or more errors occurred. (The 'data' scheme is not supported.)

But I was able to get the keys?

[ginko]

ah great, thx!

[Brish2023]

Thank you so much for this awesome tool.

I'm interested in capturing keys from a streaming service that streams only through an Android app. They don't have a website, so I couldn't use the Chrome extension.

Appreciate expert on that can describe the steps.
