Hide web accessible resources from websites

Ghost User requested to merge gorhill:experimental into experimental

Created by: gorhill

With Chromium-based browsers, web pages can access directly Decentraleyes' web accessible resources, and thus detect whether Decentraleyes is used by a visitor.

This potentially adds one bit of information to fingerprinting.

See: "Discovering Browser Extensions via Web Accessible Resources"


The change here is to use a secret when accessing a web accessible resource. If the secret is not present when the resource is fetched by the browser, the behavior will be the same as if the resource is not web accessible.

When Decentraleyes redirects a request to one of its web accessible resources, the secret is appended at the end of the local URL as a query parameter.

The secret is generated at runtime when Decentraleyes is launched.
