Google didn't turn up anything on the topic and there are some questions related to Subresource integrity on Stackoverflow but my question is: how do you generate this cryptographic hash for a CDN <link> ? In my case it is the animate.css, but I guess this can be applied to any custom CSS file.

Cheers

You can use SRIHash from Mozilla

Example using animate.css from JSDelivr

<link rel="stylesheet" 
      href="https://cdn.jsdelivr.net/animatecss/3.5.2/animate.min.css" 
      integrity="sha384-OHBBOqpYHNsIqQy8hL1U+8OXf9hH6QRxi0+EODezv82DfnZoV7qoHAZDwMwEJvSw" 
      crossorigin="anonymous">

Or you can generate it using your console :
