CSP Script Control: Hashes, Nonces, strict-dynamic
12 min read
Content Security Policy's script-src directive controls which scripts a page can run. Hashes fingerprint exact script content and work for static scripts. Nonces use per-request random tokens for dynamic content. strict-dynamic allows trusted scripts to load additional scripts. Origin allowlists trust entire CDNs and block inline scripts without explicit permission.
