Frequently Asked Questions
Common questions about this tool and how it works.
A Certificate Authority is a trusted entity that issues SSL certificates. They verify the ownership of a domain before issuing the certificate, establishing a chain of trust that browsers rely on to secure connections.
Common reasons include expiration (the date has passed), name mismatch (the domain doesn't match the certificate), or an untrusted issuer (self-signed or not in the browser's trust store). Intermediate chain issues can also cause errors on some devices.
DV (Domain Validation) only verifies domain ownership. OV (Organization Validation) verifies the business identity. EV (Extended Validation) requires rigorous background checks and often displays the company name prominently in browsers.
A cipher suite is a set of algorithms that help secure a network connection. It includes algorithms for key exchange, authentication, encryption, and message authentication code (MAC). Using outdated cipher suites can leave your server vulnerable.
