HSTS Preload List – Utility Code

HSTS is HTTP Strict Transport Security, which is a policy system for web sites to express a desire only to be contacted over HTTPS.

See https://github.com/chromium/hstspreload.org for the submission site code.

Usage

To check if a domain satisfies the requirements for preloading (assuming $PATH contains $GOPATH/bin/):

go install github.com/chromium/hstspreload/...@latest
hstspreload preloadabledomain wikipedia.org
