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.
