UNDERSTAND THE IDEA

PKI and certificates

THE CONCEPT

A real browser validates a certificate chain, hostname, time validity and policy details. This is a decision simulator, not an X.509 issuer or TLS validator.

YOUR MISSION

For each of three cases, choose “Trust” or “Reject” and read the specific reason.
