Security Response Headers Generator
Generate security response headers in generic, Nginx, and Cloudflare formats, and flag configuration risks for CSP/HSTS.
How to use the security response header generator
The security response header generator processes input only in the current browser; it does not upload, connect to the network, or save user data.
Input content
Enter site policy, source, and environment options.
Select a processing method
Select an output format and view CSP conflicts, HSTS conditions, and development environment warnings.
Check and export
Copy or download the configuration text, then validate it in the target service before deployment.
Limitations and Notes
- Does not check actual sites or guarantee that the configuration is suitable for all applications.
- Incorrect CSP, HSTS, or Permissions-Policy may disrupt operations and must not be deployed blindly.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Can the generated headers guarantee website security?
No. It is only a conservative starting point; security also depends on the application, deployment, authentication, and resource-loading methods.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
