title: Generating URL's in Laravel
body: <p>I am working on a side project on Laravel and I am a junior intern. Currently I need to generate an URL and send that to a specific email, where the user can view a pdf for a limited time and only once.</p>
  <p>For now I am just working on the unique URL generation and would like some advice for generating them securely, following standards and for a limited time only.</p>
  <p>Would love just some resources or advice.</p>
