The package exposes a single function, `in_hsts_preload()`, that accepts an IDNA-encoded hostname and returns a boolean indicating whether that domain is on the preload list. This is useful for security-conscious applications that need to enforce HTTPS-only access for known high-value targets.\n\nThe package is maintained through an automated monthly release cycle that monitors the upstream Chromium repository for changes to the HSTS Preload list. It has no runtime dependencies, installs cleanly as a pure Python wheel, and supports Python 3.6 through 3.10. The implementation is straightforward: you install it, import the function, and call it with a hostname to get a boolean result.","worth_installing":"Yes, if you need to check HSTS Preload status in your application. The package is lightweight, dependency-free, actively maintained, and permissively licensed. Install it only if you have a specific use case for preload-list lookups; it is not a general-purpose security library."},"id":"hstspreload","links":{"html":"https://skillfed.io/packages/hstspreload","md":"https://skillfed.io/packages/hstspreload.md","pypi":"https://pypi.org/project/hstspreload/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-01-01","license_spdx":null,"license_treatment":"permissive","name":"hstspreload","python_support":"supports_current","summary":"Chromium HSTS Preload list as a Python package"},"popularity":{"monthly_downloads":581131,"position":5909,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2025.1.1"}
