Common use cases

• Use ssl cert expiry hint while debugging HTTP, DNS, or TLS notes copied from DevTools, curl, or openssl output.
• Turn raw header blocks or timing logs into structured text you can paste into tickets without retyping.
• Certificate expiry from pasted openssl output.
• When the next step is a sibling HTTP or DNS check, open the related http-fetch page from More tools below.

Common mistakes to avoid

• Assuming Toolcore performs live network fetches here

  Most protocol helpers parse pasted text only. Use the HTTP fetch tool when you need a browser-side probe.

• Pasting production cookies or bearer tokens into shareable URLs

  Redact secrets before prefill links or screenshots. These pages are for shape checks, not secret storage.

• Treating heuristic output as authoritative DNS or TLS state

  CLI hints and expiry parsers reflect pasted material—verify on your infrastructure when minutes matter.
