SSL certificate checker.
Check the certificate a public domain presents on HTTPS. See its validity dates, issuer, fingerprint, and the TLS connection details reported by the provider.
Privacy: checking sends your domain and IP address directly to Domainee. Results stay in page memory; Clear removes them.
Check the certificate.
Privacy & fair use
Up to six new checks per minute in this tab. Up to 20 successful results are cached in tab memory for five minutes; the provider may also cache for about 60 seconds. Failed checks are not shown as invalid certificates. API details · Provider privacy.
One connection, a few useful details.
The provider reports a certificate and negotiated TLS parameters. Unknown fields stay unknown; this is not a whole-site grade.
- TLS connection
The provider checks one connection to the domain on HTTPS port 443.
- Certificate dates and trust
Measured values are shown when returned; missing details remain unknown.
- Identity and protocol
Subject names and the negotiated protocol describe this one connection, not a full website grade.
One negotiated connection
The protocol and cipher describe one connection made by the provider. This is not a supported-protocol matrix or a worldwide test.
Certificate signals
Trust and validity describe what the provider reports for the certificate it observed. A certificate check is not a security grade or full site scan.
Private lookup
The domain is sent directly to Domainee. Bare.io does not proxy, log, or save this check.
How to use the SSL certificate checker.
- Enter a public domain or HTTPS URL and choose Check certificate.
- Review the reported validity period and trust status, then inspect issuer and negotiated connection details.
- Use the fingerprint and chain details when comparing against your own certificate records.
The check describes one connection made by Domainee’s provider. It does not test every supported TLS version, every network location, all website security settings, or the rest of the site. Your domain is sent directly to the Domainee API; Bare.io does not receive or save it. You can also inspect DNS records, email DNS policy, and HTTP response headers.
Does a valid certificate mean the whole site is secure?
No. It reports whether the provider observed a trusted certificate within its validity period on one connection. It does not audit application code, hosting, headers, vulnerabilities, or every TLS configuration.
Does this test every TLS version?
No. The protocol and cipher are from one negotiated connection. There is no protocol support matrix or global network test.
Are lookups saved?
Bare.io does not proxy or store lookups. Up to 20 successful results may remain in this tab’s memory for five minutes, or until you choose Clear or leave the page. The API provider may cache a request for about 60 seconds; see its privacy information for provider-side handling.
