This extension is for educational and researchment purpose.

Only use it for content for which you own the rights and do not use it for piracy purposes.

How it works?

1. inject.js injected by content.js gets Widevine PSSH by hooking EME.
2. background.js fetches POST URLs/Headers
3. PSSHs will passed by this route inject.js-->content.js-->background.js-->popup.js
4. PSSHs+URLs+Headers will passed by this route background.js-->popup.js
5. popup.js will contols UI(popup.html)
6. User input into UI
7. popup.js calls pywidevine script using pyodide in browser
