What is the standard port and protocol used by HTTPS?

Explanation:
HTTPS secures web traffic by layering TLS/SSL on top of TCP, giving encrypted and reliable data delivery. The standard port for this secure web traffic is 443, using TCP as the transport protocol. So the typical match is 443 TCP. The other ports are tied to different services—80 TCP for plain HTTP, 22 TCP for SSH, and 25 TCP for SMTP—which is why they aren’t used for HTTPS.
