rswidevine

A Rust implementation of the Widevine CDM (Content Decryption Module) APIs and data formats. This project is a Rust port of pywidevine and is intended for authorized device/content validation and interoperability work.

Status

• Actively porting the core functionality from pywidevine.
• The CLI and library APIs are usable for device, PSSH, and license workflow validation.

Highlights

• Parse/export Widevine device files (.wvd).
• CDM session management and license processing.
• PSSH parsing and generation (with optional PlayReady parsing).
• Optional remote CDM client and HTTP serve API.
• Tracing-based logging for CLI.

Install

cargo add rswidevine

Or build the repo directly:

cargo build

Usage (Library)

use rswidevine::device::Device;
use rswidevine::pssh::Pssh;

let device = Device::from_path("./device.wvd")?;
let pssh = Pssh::from_base64("<pssh_base64>")?;
let key_ids = pssh.key_ids()?;
# anyhow::Ok(())

Usage (CLI)

Build with the default cli feature:

cargo run --features cli -- --help

Examples:

# Inspect a device file
cargo run --features cli --example device_info ./device.wvd

# Inspect a PSSH (base64)
cargo run --features cli --example pssh_inspect <pssh_base64>

The CLI also provides helper subcommands for license requests, device creation/export, and basic CDM checks. See --help for full usage.
