It handles the cryptographic handshake required to acquire decryption licenses from Widevine-protected services: you provide a PSSH header (Protection System Specific Header), a device provision, and a license server URL, and the library generates a license challenge, parses the server's response, and extracts the content keys. It exposes both a programmatic API (Cdm, Device, PSSH classes) and a command-line interface.\n\nThe package depends on protobuf, pymp4, pycryptodome, click, requests, Unidecode, and PyYAML. It is designed for license acquisition only, not for the full CDM lifecycle (downloading, decrypting, and decoding content). The documentation explicitly warns that content keys and decrypted data are not secure in this Python implementation and that the package requires a valid Google-provisioned device provision to operate.","worth_installing":"Yes, if you need Widevine license acquisition in Python and have a valid device provision. The package is stable, actively maintained (despite aging status), has no known vulnerabilities, and low install friction. However, the GPL-3.0 copyleft license is a hard blocker for proprietary projects, and you must obtain a Google-provisioned device provision separately\u2014the package itself does not provide one. Evaluate your legal and licensing obligations before use."},"id":"pywidevine","links":{"html":"https://skillfed.io/packages/pywidevine","md":"https://skillfed.io/packages/pywidevine.md","pypi":"https://pypi.org/project/pywidevine/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-10-27","license_spdx":null,"license_treatment":"copyleft","name":"pywidevine","python_support":"supports_current","summary":"Widevine CDM (Content Decryption Module) implementation in Python."},"popularity":{"monthly_downloads":128405,"position":11709,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.9.0"}
