About

Queries the public crt.sh certificate-transparency database (crt.sh/?q=<domain>&output=json — no API key) and returns the certificate history for each domain:

  • Per-domain summary item (pushed first): total certificates found, how many are currently valid, distinct issuer organizations, latest expiry, earliest issuance and wildcard count.
  • One item per certificate (deduplicated by serial number, newest first, capped by maxCertsPerDomain): issuer DN + issuer organization, notBefore / notAfter as ISO dates, days until expiry, the full SAN list, and a wildcard flag.

Options let you restrict to non-expired certs (excludeExpired) or widen the query to all subdomains (includeSubdomains → %.domain).

Note: crt.sh is a free community service and can be slow or briefly unavailable — timeouts on one domain are logged and the run continues with the next domain.
