What port is used for HTTPS traffic?

Because data can be sent with or without the use of SSL, one way to indicate a secure connection is by the port number. By default, HTTPS connections use TCP port 443. HTTP, the unsecure protocol, uses port 80.

Is port 443 always HTTPS?

SSL/TLS does not itself use any port — HTTPS uses port 443. That might sound kind of snooty, but there's an important distinction to be made there. Think of SSL/TLS as more of a facilitator. It enables other protocols, like HTTPS or DNS over TLS.

Is port 8443 and 443 the same?

Port 8443 in Apache Tomcat is used for running your service at HTTPS, it requires parameters to be specified as mentioned below. The above code enables SSL on port 8443, the default port for HTTPS is 443, so to avoid conflicts it uses 8443 instead of 443 just like 8080 for HTTP instead of 80.

Can I use port 80 for HTTPS?

Which one is more secure theoretically? HTTPS over port 80 may happen but only within server-to-server communication, browsers don't support that. The security is not about the port, it is about a protocol. @Anatoly browsers support HTTPS over port 80, it is just that they don't default to it.

What is the use of port 443?

Port 443 is used explicitly for HTTPS services and hence is the standard port for HTTPS (encrypted) traffic. It is also called HTTPS port 443, so all the secured transactions are made using port 443.
