What Content Security Policy Generator does

Build a defensive CSP header from explicit source and feature selections. The tool keeps the operation focused and creates a separate result so the original remains available for comparison.

Content Security Policy Generator processes the supplied input in the browser unless its interface explicitly identifies a browser-managed service.

How to use Content Security Policy Generator

Set up Content Security Policy Generator around the final use case rather than an arbitrary maximum. Test the workflow on non-critical material before processing an important source.

  1. Provide only the text, file, certificate, password-derived input, or public target required for the focused check.
  2. Review the selected algorithm, parsing rule, network scope, or policy option before running the analysis.
  3. Read each finding with its evidence and limitations instead of treating a single score or status as proof.
  4. Confirm important results through an authoritative source or approved security process before taking action.

Where Content Security Policy Generator fits

Use this security workflow for a narrow verification task or an initial diagnostic. Save the relevant input and result, compare it with an authoritative source, and involve the system owner before applying changes to authentication, certificates, headers, policies, or production data.

What to check

Start restrictive, add only sources the application needs, and deploy with reporting in staging. A generated policy must be tested against real scripts, frames, fonts, and APIs.

Treat the result as a focused diagnostic, not a security guarantee. Confirm findings with current browser behavior, authoritative documentation, and an approved scanner before changing a production system.

Privacy and limitations

Local inspection stays on this device. Network checks are explicitly labeled and send only the target required for the request.

A focused browser or network check sees only the submitted material and the signals it is designed to inspect. It cannot certify identity, remove malware, prove a site is safe, replace a penetration test, or predict every attack technique.
