How this service works
Inspect a host's live TLS certificate: subject, issuer, valid-from/valid-to dates, serial, SHA-256 fingerprint, TLS protocol and cipher, and whether the chain is trusted.
Output
Returns the certificate's subject (CN, SAN, org), issuer details, valid-from and valid-to dates, serial number, SHA-256 fingerprint, negotiated TLS protocol version, cipher suite, and a boolean indicating whether the certificate chain is trusted by the system's root store.
Example use cases
Pre-launch SSL certificate audit
“Before we go live, can you check the TLS certificate on staging.myapp.com port 443 — I need to know the issuer, expiration date, TLS version, cipher suite, and whether the chain is fully trusted?”
Certificate expiry monitoring
“Check the SSL cert for payments.acme.com and tell me how many days until it expires and whether the certificate chain is currently trusted.”
Security compliance check
“I need to verify that legacy.internaltools.com on port 8443 is using a modern TLS protocol and not something outdated like TLS 1.0 — can you inspect the live certificate and report the protocol and cipher?”
Technical details
Endpoint
GEThttps://164.160.90.241.sslip.io/api/sec-ssl-tls-cert-inspector?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, real-time TLS certificate data directly from the server — including expiry dates, fingerprints, protocol version, and chain trust status — rather than cached or third-party lookup data. Ideal for compliance audits, pre-deployment checks, certificate expiry monitoring, and confirming cipher/protocol configurations.
Side effects
- Hostname not resolvable — DNS lookup failure
- Connection refused or timeout if host is unreachable on specified port
- Certificate chain untrusted — returns trust=false rather than an error
- Invalid hostname format provided
- Port outside valid range causes a validation error
- Host presents no TLS certificate (plain HTTP only)
