A Chrome extension that demonstrated bypassing Widevine L3 DRM by hijacking Encrypted Media Extensions calls to extract content decryption keys in plaintext. It has been non-functional since May 2021 after Google patched the CDM and issued a DMCA takedown, and now serves mainly as a reversing writeup and archive.

Use cases

  • study how Widevine L3 DRM was bypassed in Chrome
  • learn reverse engineering of the Widevine Content Decryption Module
  • understand Encrypted Media Extensions key flow
  • research DRM security-by-obscurity weaknesses
  • decrypt CENC media streams with extracted keys using ffmpeg

When to choose

  • you want to study the archived writeup on reversing the Widevine CDM
  • you research DRM protection schemes and obfuscation limitations

When to avoid

  • you need a working DRM bypass today - it stopped working in May 2021
  • you want a tool for decrypting protected streaming content
  • you need something legally safe to redistribute - Google DMCA'd its forks
