TLS certificate

A TLS handshake on port 443 that extracts the peer certificate: validity, SAN, hostname match, chain of trust, negotiated protocol/cipher and cryptographic checks with transparent scoring.

I confirm I have explicit authorisation to analyse this domain.

TLS 1.2+ · SAN · chain of trust · cipher · ~3–12 s · requires a (free) account

Method: the connection uses rejectUnauthorized: false so that untrusted certificates can be inspected too (teaching and authorised OSINT only). For a complete URL scan use the URL check.
