Certificate Chain Resolver
Find the issuer chain, check its signatures and download the certificates in installation order.
Chain result
Verified to a trusted CA
Signatures, certificate constraints and dates have been verified against a CA in this server’s trust store.
Complete chain, but the root is not trusted here
The path and dates passed, but the self-signed root is not in this server’s trust store. This is not a public trust guarantee.
Incomplete chain with a missing issuer
The available path passed its checks, but it does not reach a trusted CA or a self-signed root. Do not treat this as a verified full chain.
Chain validation failed
A date, signature or certificate constraint has prevented validation. Downloads are for diagnosis. Do not install them as a verified chain.
Some supplied certificates were not part of the selected path:
At least one issuer lookup was blocked, unavailable or exceeded a limit. You can supply the missing issuer certificate manually.
Certificates retrieved from issuer URLs:
Choose your download
PEM-encoded .crt files. Choose the option required by your server or hosting panel.
Server Certificate + Intermediates
Your certificate first, then the intermediates, without the root. Use for a combined certificate or fullchain file.
Intermediate Certificates Only
Intermediates only, without your certificate or the root. Use for a separate CA bundle field.
All Chain Certificates
Every certificate in the resolved chain, including the root when available. Use for inspection or when the complete chain is explicitly requested.
