You should have Nodejs installed on your laptop and if not, check the Node.js official website, and download/ install the latest and stable release.

Node.js

To install and run Ember.js, you'll need to follow these steps: Install Node.js and npm (Node Package Manager) on your computer. You can download the latest version of Node.js from the official website. Once Node.js and npm are installed, open a terminal window and run the following command to install the Ember.js command line interface (CLI):

NodeJS - Link

To get involved in the Node.js developer community, you can join community discussions or begin with learning if you’re new. The community discussion houses a GitHub list of issues related to Node.js' core features. If you want to chat in real time about Node.js development, there are Slack groups, and you can still connect with IRC clients or web clients when using the browser. Node.js has a calendar for public meetings.

Download the latest version from the Node.js website, open the package installer, and follow the instructions Use a package manager like Homebrew with the command brew install node On Linux, you can consult this page to determine how you should install Node.

As with all experimental things, a few things are missing. Some of these might lead to people using dotenv until support for these gets added. I will mention them here and let you see if they are dealbreakers. You can also follow the GitHub issue to track missing feature support.

It's a part of the browser. It's not doing it with Javascript if that's what you're asking. Chrome includes a file with the name widevinecdm.dll or something like that on Windows. No one knows exactly what this file does because it is incredibly obfuscated https://github.com/tomer8007/widevine-l3-decryptor/wiki/Reve....

As for what Widevine actually does, it just uses a protobuf based protocol to request a decryption key from a license server. License request messages from the client have to be signed with a valid device private key, which are made difficult to extract but some occasionally leak.

Not just privately either, there have been tools circulating even on GitHub.

For a L3 example there's one repo [1] that's kind of still up but not really. Still enough to show that it happened. L1 bypass has also been on GitHub briefly. However these things get deleted rather fast for obvious reasons.

Widevine has been broken at least a few times, including by recovering the private key from its white-box implementation: https://github.com/tomer8007/widevine-l3-decryptor/wiki/Reve.... Note that the write-up says it was the "old" version, but that's relative to the date of the write-up. Google overhauled Widevine after he broke it.

I'm less familiar with shielding data like this, but historically things like VMProtect and Themida were the standard for shielding programs. These offer a degree of resistance to automation, but a determined human will eventually figure them out, and then automation usually follows anyway. Syntia did this for VMProtect and Themida: https://www.usenix.org/system/files/conference/usenixsecurit....

For webrip you'll need an hdmi splitter that doesnt abide by HDCP to bypass protections into a capture card. For webdl theres this older github but it doesn't work anymore, im not sure if there's a currently working script and key online publicly https://github.com/tomer8007/widevine-l3-decryptor

There's code for the L3, but it doesn't work since end of may because the new RSA keys aren't public

https://github.com/tomer8007/widevine-l3-decryptor

Find the code in the forks, since it was DMCA'd

There's none for L1 and L2 though

So if for example I `git clone` ed this project back when it was live with the original files, and then `git pull ` now after the maintainer removed project files and all the relevant commits with it, the `git pull` command would just fail?

You can still bypass DRM if you know how or have to programms to do it (With widevine-l3-decryptor for example (The offical key(s) was/were revoked but some people still post keys))
