CSP Nonce

Definition

A CSP nonce is a unique, random value generated per page load that helps validate legitimate inline scripts within a Content Security Policy. By adding this nonce to both the CSP header and allowed script tags, developers can permit specific inline scripts while maintaining strong XSS protections. This approach is particularly useful when dynamic script insertion is necessary but a strict CSP is desired.
