Build strict Content-Security-Policy headers to eliminate XSS and clickjacking.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Set origins for default-src, script-src, style-src, and connect-src.
Protect against clickjacking with frame-ancestors 'none'.
Copy Content-Security-Policy HTTP header for your web server.
It instructs browsers to automatically upgrade HTTP resource requests to HTTPS before fetching.
frame-ancestors is the modern CSP Level 3 standard for anti-clickjacking framing control.
Zero-egress companion tools in the Security & Network suite
Measure cryptographic randomness, Shannon entropy (0-8 bits/byte), Chi-square test, and byte distributions.
Brute-force all 256 single-byte XOR keys with automated English frequency & chi-squared scoring.
Audit CSP, HSTS, X-Frame-Options, and security headers with OWASP grading (A+ to F).
Compare memory hardness, GPU ASIC resistance, and security parameters across KDF standards.
