SSL Checker Soon

Inspect the TLS certificate a host presents: subject and alternative names, issuer, validity dates, key size and whether the chain is complete.

This tool is on the list but not live. What it needs is written below, so it is a matter of building it rather than finding out.

What is missing

Reading a certificate needs a raw TLS handshake. Neither a browser nor a Cloudflare Worker exposes the peer certificate, so this needs an endpoint on dotbunker-api (Go crypto/tls).

cloud

Runs on our edge servers

A browser cannot read another site's response, so a dotbunker edge server fetches it and reports back. Nothing is stored.
