What this tool does
Extract HSTS Directives splits pasted Strict-Transport-Security headers into rows such as max-age, includeSubDomains, and preload so release notes, CDN checks, and migration tickets are easier to compare.
Common use cases
Split pasted Strict-Transport-Security headers into HSTS directives for local HTTPS rollout review, CDN migration notes, and release handoffs.
Use Extract HSTS Directives when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste copied Strict-Transport-Security headers, CDN notes, deployment logs, documentation, or support-ticket snippets.
- Choose whether duplicate directives should be removed and whether output should be normalized for comparison.
- Review source-line context, then copy the clean directive list for HTTPS rollout notes, release QA, CDN migration, or policy handoff.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Extract HSTS Directives runs locally in your browser. It does not check live domains, change preload status, fetch URLs, upload, store, or log pasted headers.
