Current crates.io version License Docs CI status

Rust implementation of Google's Widevine DRM CDM (Content Decryption Module). The CDM allows you to build applications that can access DRM-protected media.

This is a port of the pywidevine library by rlaphoenix.

To use the CDM you need a valid Google-provisioned Private Key and Client Identification blob (plain or bundled as a *.wvd file).

Example:
