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
