01overview

What this tool does.

Perform a safety-bounded TLS handshake to a public hostname on port 443, pinned to a validated public IP while preserving SNI and hostname verification. The tool reports the leaf certificate, SANs, issuer, validity, fingerprint, chain summary, protocol/cipher and trust/hostname status without allowing arbitrary target ports.
