Create Content Security Policy rules for modern web apps and output both HTTP header and meta tag formats. This tool helps reduce XSS risk by defining trusted script, style, image, and connect sources. It is useful during security hardening, penetration testing, and production rollout checks.
Frequently Asked Questions
What is CSP used for?
CSP limits which sources can load scripts and other resources, reducing XSS and injection risks.
Should I use HTTP header or meta tag?
HTTP header is preferred in production. Meta tag can help for static hosting scenarios.
Can CSP break existing pages?
Yes if sources are too strict. Start with report-only strategy and tighten rules gradually.
