security.txt Generator

Generate a security.txt File with the Fields Researchers Actually Need

This security.txt generator is designed to create a publishable contact and disclosure file that follows the modern security.txt pattern. The current form includes the key fields a real deployment usually needs: required Contact and Expires values, optional Encryption, Acknowledgements, Policy, Hiring, Canonical, and CSAF fields, plus preferred languages. The interface also lets you add multiple contact, policy, hiring, canonical, or CSAF entries where the workflow benefits from more than one line.

That makes the page useful for security teams, developers, operations teams, and site owners who want a clean vulnerability-reporting path without hand-writing the file every time. Instead of memorizing field names and formatting rules, you fill in the values, generate the text, and publish it where researchers can find it.

Key Features

• Guided builder for the core fields a real security.txt file usually needs, including required contact and expiry details.
• Support for optional fields such as encryption, acknowledgements, policy, hiring, canonical, and CSAF links.
• Multi-entry add controls for fields that often need more than one line in a production deployment.
• Useful for security-contact clarity, responsible disclosure workflows, and security-team discoverability.
• Good fit for teams that want a standards-aligned file without hand-formatting it from scratch.

Use Cases

• Create a first security.txt file for a site that wants a clear vulnerability-reporting path.
• Refresh an existing security.txt file when contact channels, policy URLs, or expiry dates change.
• Pair the generated file with HSTS Tester when you also need to validate a transport-related security signal on the same site.
• Add preferred-language guidance and policy links so inbound reports reach the right people with fewer delays.
• Publish a more trustworthy disclosure posture for partners, researchers, and customers.

How To Use

1. Start with the required fields: contact and expiry. Those are the minimum backbone of a usable security.txt file.
2. Add optional fields only where they genuinely help the reporting workflow, such as encryption details, a disclosure policy, acknowledgements, canonical URL, or CSAF location.
3. Use the add controls when you need more than one contact, policy, or canonical entry rather than trying to compress several values awkwardly into one line.
4. Generate the file and review it once before publishing. If the broader site security posture still needs attention, continue with Secure Cookie Tester after the reporting path itself is in place.
5. Publish the finished file at the correct location on the site and refresh it before the expiry date makes the file look stale or neglected.

How It Works

A security.txt file gives researchers a standardized place to find disclosure contact details and supporting information for a website or service. The generator assembles the file from the values you provide, which removes the guesswork around field names and makes it easier to keep the format clean and consistent.

The most important interpretation rule is that security.txt is operational, not decorative. A beautiful file is not useful if the contact route is unmonitored or the expiry date is ignored. A good sanity check is to send a dry-run internal report through the listed contact method and confirm that the process actually works.

Examples

Initial vulnerability-reporting setup

A team adds a mailto contact, a disclosure policy URL, preferred languages, and an expiry date, then publishes the generated file as the first clear reporting channel for the site.

Annual refresh and expansion

A mature team revises the expiry date, adds a canonical URL and acknowledgements page, and publishes the updated file so researchers see a current, credible disclosure posture.

Edge Cases & Troubleshooting

• If the file is published but the contact path is not monitored, the reporting workflow still fails in practice.
• Expired files signal neglect and reduce trust, so review and refresh the Expires value before it goes stale.
• Only include optional fields that your team will actually maintain. Dead links are worse than omitted links.
• Canonical and contact details should point to live, reachable resources that belong to the site or organization.
• Publishing the file is only the first step. Make sure internal triage and acknowledgement processes exist behind it.

FAQ

What is this page best for?

It is best for creating a clean security.txt file with the contact, policy, and supporting fields researchers need to report issues responsibly.

Which fields matter most?

Contact and Expires are the essential starting point. The other fields help when they genuinely improve the reporting path.

What should I verify after generating the file?

Verify the contact route, confirm the URLs work, publish the file at the right location, and set a reminder to refresh it before expiry.
