Encryption hides the conversation, but it can&rsquo;t tell you <em>who</em> is on the other end. That is the job of a <strong>public key infrastructure (PKI)</strong>: certificates that bind names to keys, signed by <strong>certificate authorities (CAs)</strong> that you decided to trust ahead of time. The protocol that puts it all to work on a connection is <strong>TLS</strong>, the &ldquo;S&rdquo; in HTTPS. This page builds TLS and PKI up one idea at a time, with no math. It ends with why the web&rsquo;s PKI is invisible to almost everyone, and why a private network like Deevnet runs its own.</p>
