When to use this tool

Check the order and issuer relationships of server and intermediate certificates before configuring a certificate bundle.

Paste the available PEM certificates together, or start with the chain example.
Inspect the inferred paths and local signature checks, including missing or ambiguous issuer notices.

A linked chain is not an OS trust decision. Missing certificates cannot be downloaded by this tool, and revocation services are not queried.
