 "Content-Security-Policy": "default-src 'self';script-src 'self';connect-src 'self' http://localhost:* https://icp0.io https://*.icp0.io https://icp-api.io;img-src 'self' data:;style-src * 'unsafe-inline';style-src-elem * 'unsafe-inline';font-src *;object-src 'none';base-uri 'self';frame-ancestors 'none';form-action 'self';upgrade-insecure-requests;",

 This CSP includes `img-src data` as data images are frequently included in frontend interfaces, and `frame-ancestors: none` is used to mitigate [clickjacking attacks](https://owasp.org/www-community/attacks/Clickjacking).
 
+## Asset certification
+
+The [ic-asset-certification](https://crates.io/crates/ic-asset-certification) Rust crate can be used to:
+
+- Serve certified assets from the same canister as their primary “backend” canister.
+
+- Embed assets directly into a canister’s Wasm rather than uploading them at runtime.
+
+- Create custom routing logic, such as:
+
+    - Serving 404 pages in multi-page apps.
+
+    - Serving multiple frontends from the same canister.
+
+    - Certify more complex caching or streaming scenarios.

 ## Security recommendations
 
 This default Content Security Policy aims to work with as many applications as possible rather than providing the maximum security. It is recommended that you update this policy for your application's specific needs by utilizing tools such as:

 ## Limitations
 
 The frontend canister can host roughly 1GiB in static files. It is recommended that you distribute your files across multiple canisters if the total size of all your assets begins to exceed this amount. Once you exceed this figure, your canister may fail to upgrade.
