hsts

Package hsts provides access to the Chromium HSTS preloaded list.

The list is manually converted into go code occasionally with go generate.

To request your site be added to the list, please visit hstspreload.org.

Usage

import "go.tmthrgd.dev/hsts"

Hostnames (or domain names) can be checked for inclusion in the list by calling IsPreloaded:

if hsts.IsPreloaded(hostname) {
	// ...
}

Transport is a http.RoundTripper that automatically upgrades insecure http requests to hosts in the preload list into secure https requests. It can be used by setting the (*http.Client).Transport field as follows:

client := &http.Client{
	Transport: &hsts.Transport{},
}
resp, err := client.Do(req)
