Inspect live certificates
Check issuer, validity dates, and remaining days for a hostname before troubleshooting HTTPS.
Utilities
Check an SSL certificate
Inspect the live TLS certificate for a hostname and review issuer, validity dates, and remaining days.
Processed on the server.
Do not paste passwords, tokens, or private keys.
Results will appear below the editor after you run the tool.
Useful after domain setup
Confirm whether the browser should trust a domain after DNS and certificate provisioning.
No private key access
The checker reads public certificate information from the live TLS connection only.
How to use SSL Checker
Check the public certificate presented by a hostname before diagnosing HTTPS or domain issues.
Enter a hostname
Use a domain such as example.com without pasting private certificate files.
Run the check
StaticX connects to the host and reads the public certificate metadata.
Review dates
Check issuer, valid-from date, valid-to date, and days remaining.
Certificate issues are easiest to debug from the outside.
A site can have correct files but still feel broken if HTTPS is not active. Checking the public certificate helps separate DNS, certificate, and browser trust issues.
For StaticX custom domains, keep the required DNS record in place so certificate renewals can continue automatically.
Certificate checks to remember
Public metadata only
The checker never needs private keys, certificate uploads, or account secrets.
Propagation can take time
A new domain may need time before the correct certificate is visible everywhere.
Use exact hostname
www.example.com and example.com can have different certificate coverage.
Questions about SSL Checker
Short, practical answers for using this page safely.
Does this renew certificates?
No. It only inspects a live public certificate. Renewal depends on the hosting/domain setup.
Why does the root domain differ from www?
They are separate hostnames and may have different DNS and certificate coverage. Check both if both are used.
Should I paste certificate files?
No. Enter only a public hostname.
