SSL Certificate Checker
Inspect one public hostname’s verified TLS connection and available certificate evidence. Free, with no paid data API.
Understand the certificate.
See this connection clearly.
Inspect one public hostname’s TLS connection and the certificate evidence returned by that endpoint. Review verification, dates and certificate names in one focused report.
What this endpoint presents.
Connection & verification
Leaf certificate
Certificate names
Names are certificate metadata. Their presence alone does not establish a verified connection.
Presented certificate chain
Evidence notes & limitations
This check connects to one public IPv4 address for your hostname on port 443. It does not fetch an HTTP page, scan every address, check certificate revocation, or provide an SSL Labs grade. A connection failure leaves certificate status unknown. Results reflect this checker’s connection and trust store at the time shown; no visitor account or saved history is created.
What this check tells you
Does this use a paid API?
No. The checker opens one protected TLS connection from this server using cURL and OpenSSL. It does not use a paid certificate database or send an HTTP page request.
Does a timeout mean a certificate is invalid?
No. Network failures and timeouts are not certificate verdicts. The report separates connection outcome, available certificate metadata and validation evidence.
What does a verified result prove?
It means this one TLS connection passed peer and hostname verification against this server’s trust configuration at the recorded time. It is not a guarantee for every browser, device, address or CDN edge.
Can this check every SSL security issue?
No. This version does not supply an SSL Labs grade, vulnerability scan, exhaustive cipher/protocol audit, revocation check or uptime monitoring. It tests one public IPv4 endpoint on port 443 and does not follow certificate URLs.
Are submitted hostnames and reports saved?
This module does not save visitor reports or create recurring jobs. Shared security/usage counters and ordinary server logs can still exist. The administrator can disable checks, change the timeout, control exports and assign the page.
