PyDCSL 🛡️🔐

A compact Python tool to check if a Widevine device certificate (DCSL) is revoked or valid.

📦 What is PyDCSL?

PyDCSL is a lightweight Python utility that interacts with a custom API to process Widevine license components — specifically .wvd, client_id, and private_key files — and fetch the corresponding DRM metadata.
It acts as a tool for DRM inspection, metadata extraction, and license validation purposes. The tool provides both a command-line interface (CLI) and an importable Python module.

⚙️ Features

• 🧾 Accepts .wvd, client_id, and private_key inputs
• 🌐 Sends requests to a Widevine DCSL-compatible API
• 📊 Pretty-prints extracted metadata using rich (if available)
• 🧪 Supports both CLI and importable module
• 📁 Optionally saves results to a JSON file
