The simplest CSP policy. See how default-src 'self' blocks injected inline scripts.

Trust scripts by origin URL. Any script loaded from a listed domain runs without a nonce or hash.

A per-request random token in the header and script tag lets one specific inline script run.

A cryptographic hash of the script content. Only scripts whose content matches the hash are allowed.

Lets a trusted script inject further scripts, so third-party scripts work without allowlisting domains.

Split script rules by category. Allow inline event handlers while keeping <script> blocks protected by nonces.
