What is the port number for SSL?
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.
How do I find my SSL port number?
(Use netstat -t -l -p -n if you just want the port number, in which case you’ll see *:443 instead of *:https ). This tells you that there’s a socket listening on port 443.
Why is SSL on 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.
Is SSL always on port 443?
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 443 the only SSL port?
We can use any available port for HTTPS, however, for the sake of convention, 443 and 8443 are assigned for HTTPS (browsers automatically prefix with https when these port numbers are used), but we can even run HTTPS on port 80.
What are ports 80 and 443 used for?
Port-443 allows data transmission over a secured network, while Port 80 enables data transmission in plain text. Users will get an insecure warning if he tries to access a non-HTTPS web page. Port 443 encrypts network data packets before data transmission takes place.
Can I use port 8080 for HTTPS?
You should not use port 8080 for https traffic. That port is conventionally used for non-secured data, akin to the use of port 80 for default external http. Port 8443 is the standard for Tomcat secured (SSL/TLS) data, corresponding to the common HTTPS port 443. You cannot use the same port for both http and https.
Can I run SSL on port 80?
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.
