Using SSL Certificate Checker for open banking
Inspect a public HTTPS endpoint’s certificate chain, validity and hostname checks.
Sandbox example and expected result
Check https://example.com to view the leaf certificate and chain reported by the remote endpoint.
Limitations and troubleshooting
This inspects server TLS, not your client mTLS identity or every bank-specific trust requirement. Only public HTTPS destinations are supported.
Where your input is processed
The hostname is sent to our server, which connects to the public endpoint on port 443. Use synthetic test data.
