HTTPS Port 443 vs Port 8443
What is the Difference Between HTTPS Port 443 and Port 8443

The key difference between HTTPS port 443 and port 8443 is that Apache Tomcat uses 8443 to open SSL text service to avoid conflicts, whereas 443 is a web browsing port meant to secure data transmission between web browsers and servers. So, although both of them are HTTPS ports, yet, Tomcat distinguishes the default configuration as 8443.

What is HTTPS?

HTTPS or Hypertext transfer protocol secure refers to the secure version of HTTP. HTTP is the application-layer protocol that is required for transmitting hypermedia documents like HTML. It was initially designed for seamless communication between web servers and browsers. However, now it offers a wide range of functionalities, and HTTPS is encrypted to increase the overall security of data transfer.

HTTPS is important as it enables users to transmit their company's sensitive data and information like email services, logging into banking accounts, or insurance information. Ideally, any website requiring user credentials and sensitive data must use HTTPS. Browsers like Chrome mark websites differently if they lack HTTPS.

What is HTTPS

As per the image demonstrated above, HTTP is responsible for transferring data between the web server and web browser, while HTTPS is responsible for sending the data in an encrypted format. So, the latter offers an advanced layer of security that prevents hackers from reading or gaining any access to the data transferred between the web server and browser. The encrypted link is established by HTTPS using the SSL (Secure Socket Layer) or TLS (Transport Layer Security) protocols, which is the new version of SSL.

What is HTTPS Port 443?

Port 443 is nothing more than a virtual port that is used by computers for diverting network traffic. Almost every user accessing the internet uses such ports every single day. So, any search you conduct every day on your computer needs to connect with a server responsible for hosting that information and thereby fetches the same for you.

Such connections are established via a port which can be HTTP or HTTPS port. These precursors are visible on the web addresses, depicting the port they use. But it is essential to understand the key differences between HTTP and HTTPS ports.

HTTPS Port 443

As already highlighted, HTTPS is secured and available on port 443, while HTTP is unsecured and available on port 80. Port 443 is used for transferring information that is encrypted using SSL or TLS and hence offers a safer option for data security. That is why it is always advisable to conduct transactions on websites with HTTPS, as it helps secure your customer information, business-critical data, and passwords from being stolen and intercepted.

What is 8443 Port?

Tomcat is known for using the default port 8443 for SSL HTTPS traffic. It is ideal for avoiding any port conflict while setting the proxy or caching server traffic for ports. So, port number 8443 is another alternative to the HTTPS port, which acts as the primary protocol for Apache Tomcat while using the web servers to open SSL text services.

Tomcat refers to the core project in the Jakarta project, belonging to the Apache Software Foundation. It was developed by Sun, Apache, and multiple companies, where the default configuration file used by Tomcat to distinguish the port is 8443.

Apache Software

The 8443 configuration is defined as the protocol that serves as the communicative tool with a set of formalized rules to explain how the data will travel over a network. One can consider this to be the language between the computers, helping them communicate seamlessly.

For example, let's consider Protocol HTTPS, which defines the communication format by generating authentication key pairs for the user, kept within the web browser.

What is the Difference Between HTTPS Port 443 & Port 8443?

For opening the SSL text service, Apache Tomcat uses 8443 as the default configuration for defining the port. Port 8443 must add a port number during the visit, which will be the equivalent of HTTP 8080, whereas port 443 can get access without specifying any port number, which is the equivalent of HTTP 80. While 8443 cannot be directly accessible through the domain name, 443 can do that easily.
