CSP Generator & Evaluator

CSP Generator & Evaluator

Build and validate Content Security Policy headers with a visual interface. Generate CSP headers by selecting directives and source values, or evaluate existing policies by pasting them for syntax validation and security analysis.

Как использовать

Generate mode: Select a preset (Strict, Moderate, or Permissive) or customize individual directives like default-src, script-src, style-src, and more. Toggle options like upgrade-insecure-requests and Report-Only mode. Click Generate to produce a complete CSP header.

Evaluate mode: Paste an existing CSP header string to parse all directives, identify security warnings (like unsafe-inline usage), and receive an overall security rating.
