Understanding SSL/TLS Handshakes
A Certificate (X.509) is a digital passport that proves a website is who it claims to be. It is signed by a Certificate Authority (CA) like Let's Encrypt or DigiCert.
Chain of Trust: Your browser trusts a set of "Root CAs". A website sends its certificate plus "Intermediate" certificates to build a path back to a Root CA. If this chain is broken, you'll see a "Your connection is not private" warning.
