SSL Certificate Checker

Inspect any site's live SSL/TLS certificate by connecting directly over TLS — no third‑party API, just the real handshake.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

For each host, straight from the TLS handshake:

Validity — valid, expired, notYetValid, selfSigned, plus daysToExpiry for renewal alerts
Identity — subject, issuer, commonName, and all Subject Alternative Names (san)
Dates — validFrom / validTo (ISO‑8601)
Crypto — serialNumber, fingerprint256, keyType, bits, negotiated protocol, keyUsage
Chain — full issuer chain walked to the root, with chainLength

Single host or bulk, any port (defaults to 443).

Input

{
  "hosts": ["github.com", "https://google.com", "expired.badssl.com:443"],
  "port": 443,
  "maxHosts": 50
}

You can also pass a single host (or url) string.

Output

{
  "host": "github.com",
  "port": 443,
  "valid": true,
  "issuer": "CN=Sectigo ECC Domain Validation Secure Server CA, O=Sectigo Limited, C=GB",
  "subject": "CN=github.com",
  "commonName": "github.com",
  "san": ["DNS:github.com", "DNS:www.github.com"],
  "validFrom": "2025-02-05T00:00:00.000Z",
  "validTo": "2026-02-05T23:59:59.000Z",
  "daysToExpiry": 226,
  "expired": false,
  "selfSigned": false,
  "serialNumber": "0A1B2C...",
  "fingerprint256": "AB:CD:...",
  "protocol": "TLSv1.3",
  "chainLength": 2,
  "chain": [ { "subject": "...", "issuer": "...", "validTo": "..." } ]
}

Failed hosts still return a row with an error field, so a single bad target never breaks the run.
