Chromium HSTS Preload list as a Python package and updated daily

Project description


Chromium HSTS Preload list as a Python package and updated daily.

Install via python -m pip install hstspreload

See for more information regarding the list itself.


The package provides a single function: in_hsts_preload() which takes an IDNA-encoded host and returns either True or False regarding whether that host should be only accessed via HTTPS.


This script gathers the HSTS Preload list by monitoring this file in the Chromium repository. Changes to the HSTS Preload list can be seen in the history of that file.
