Description

In order to ensure that Stylesheets and JavaScripts resources are integrated without being compromised, according signatures have to be added:

Documentation:

For static files

Example

<script src="https://example.com/example-framework.js" 
        integrity="sha384-oqVuAfXRKap7fdgcCY5uykM6+R9GqQ8K/uxy9rx7HNQlGYl1kPzQho1wx4JwY8wC" 
        crossorigin="anonymous"></script>

This step also requires that signatures have to be generated every time the source code is modified in Git commits. Dynamically generating signatures does not make sense since that would just sign compromised data as well. The "trust aspect" is still target to be defined here - in terms of "how to verify that signatures are not compromised".

For ("unsafe") inline assignments

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src#Unsafe_inline_script

Example

Content-Security-Policy: script-src 'nonce-2726c7f26c'
<script nonce="2726c7f26c">
  var inline = 1;
</script>

→ done with #100141 - but only in the scope of content-security-policy headers, not in general for the integrity attribute, which has a different scope
