Bulk SSL/TLS Certificate Expiry and Chain Checker
Know which certificates are about to expire, or are already broken, across hundreds of hosts. Opens a TLS connection per host and reads the public certificate; no data is sent, no personal data collected. Schedule it daily and alert on status: critical.
What is checked
- Days remaining, valid-from/to, issuer, subject, SANs, serial, SHA-256 fingerprint.
expired,expires-critical(default 14 days),expires-soon(default 30 days),not-yet-valid.hostname-mismatch(certificate does not cover the host),self-signed,incomplete-chain(missing intermediates),untrusted, expired intermediates.weak-key(RSA under 2048),old-protocol(TLS 1.0/1.1 negotiated),long-lifetime(over 398 days).- Protocol, cipher, ALPN, key type and size, full chain as sent by the server.
- Private/reserved addresses are refused (SSRF guard, also for DNS results). One connection at a time per host with a small delay.
- Note: trust is evaluated against the Node.js CA store of the actor image.
Input
| Field | Default | Description |
|---|---|---|
hosts | required | Up to 10,000: host, host:port or URL. |
port | 443 | Default port (use 465/993/8443 for mail or other TLS services). |
warnDays / criticalDays | 30 / 14 | Status thresholds. |
delayMs / concurrency | 100 / 8 | Politeness. |
Output
One item per host: status (ok / warning / critical / error), daysRemaining, certificate fields, chain[], issues[].
{ "host": "expired.badssl.com", "status": "critical", "daysRemaining": -4195, "issues": [{ "severity": "high", "id": "expired" }] }
Pricing (pay per event)
apify-actor-start $0.005 per run (per GB), host-checked $0.0018 per host (failed connections are charged too, since the check ran; invalid inputs are not).
Develop
npm install && npm test (needs openssl for one test); local run with storage/key_value_stores/default/INPUT.json and npm start; deploy apify push (private by default).
