I have tested SRI for js includes, it works just fine, but is currently supported only by FF, Chrome and Safari 11. It requires, however, enabling CORS `Access-Control-Allow-Origin` header on...
I have created [integrity](https://github.com/textpattern/textpattern/tree/integrity) branch, where `textpattern.js` is served via a basic `server.php` script and imported with `integrity` attribute. In my tests (FF57 W7) the file is served with roughly...
