What is a Certificate Chain Validator?
A certificate chain validator checks that your SSL/TLS certificates form a complete, valid chain from the leaf (server) certificate through intermediates to a trusted root CA. Incomplete chains are one of the most common causes of SSL errors.
This tool runs entirely in your browser — no certificates are sent to any server.
