TLS certificate expiry for up to 10 hostnames
TLS certificate expiry for up to 10 hostnames: the issuer, validity dates, days left, all DNS names and a status (ok, expiring within 14 days, expired, none found). Read from Certificate Transparency logs (CertSpotter, crt.sh as fallback), so it is the newest valid certificate issued for each name, not the one the server presents; the answer also says whether https answers and its HSTS header. Public hostnames only.
