UrlSigner class final

Signs and verifies URLs with HMAC-SHA256 (Laravel URL::signedRoute).

The signature covers the path and query string (not the scheme/host), so links stay valid behind reverse proxies that rewrite the host; this is a documented deviation from Laravel, which signs the absolute URL.
