While browsing the internet we often encounter the HTTPS port at the beginning of a website address. It is a communication channel over the Internet that is apparently more secure than other protocols such as HTTP. But what exactly is the HTTPS protocol? How is it different? What port does it use? How does it work? And why does the padlock icon appear in Chrome’s address bar when clicking on a website using an HTTPS port?
If you are confused by all of these questions, don’t worry; We have you covered. In this article, we’ll go through everything you need to know about HTTPS ports in simple terms. Whether you want to launch your website or protect your online data and privacy, knowing about HTTPS ports will help.
So, let’s dive in without further ado.
What is an HTTPS port?
HTTPS stands for Hypertext Transfer Protocol Secure. HTTPS ports encrypt connections using SSL (Secure Socket Layer) or TLS (Transport Layer Security) to provide an additional layer of security when accessing a site. Each port has a dedicated number that distinguishes it from the others.
Port 443 or 8443 is used for HTTPS connections that protect web browser communications. For example, when you access an HTTPS website, it sends a request to its hosting server for special services using network port 443 or 8443. The server then connects to the requested port, which is encrypted in the case of HTTPS, to send the service to the website.
As a result, those who use web hosting servers can send and receive data over the Internet without any security concerns.
How does HTTPS encrypt data transmitted over the network?
HTTPS uses SSL or TLS certificates to encrypt and secure data transmission. SSL and TLS work similarly and many people use the terms interchangeably. However, TLS is an updated and improved version of SSL. Nowadays, more and more HTTPS websites are upgrading their protocol to the TLS version, which is more secure than SSL.
HTTPS protocol vs SSL/TLS protocol
Now that you understand the difference between TLS and SSL let’s see how HTTPS ports and SSL/TLS work to establish a secure connection. Websites run on the HTTPS protocol, while HTTPS runs on an SSL/TLS certificate. It’s installed on a web hosting server to provide a secure and encrypted connection between a website and a web browser. The SSL protocol authenticates the identity of users whenever they want to transmit information. HTTPS then provides the channel to transfer that information to the server.
Thus, these protocols work alongside each other to provide a secure connection between the web browser and the website server.
HTTPS vs HTTP
Websites that use SSL certificates run on HTTPS, while sites without SSL/TLS run on HTTP ports. The HTTPS protocol dictates that data sent over the channel is impossible to encrypt and read, while websites using the HTTP protocol send and receive data in plain text.
Be careful when sending your sensitive information, such as credit card details, personal information, login credentials, etc. online. Make sure a website uses the HTTPS protocol, which encrypts its data and verifies its identity. This way, you can be sure that your data is not at risk.
However, URLs preceded by the HTTP protocol are insecure and may use your data for other purposes.
How to distinguish HTTP from HTTPS protocol
To ensure that a website is using an SSL/TLS certificate, you have two main ways:
Read the URL before clicking a website link in a browser. If the URL starts with the HTTPS protocol, your data will be secure.
After visiting the website look for the padlock icon before the domain name in the search bar. You can view site information and connection details by clicking on the padlock.
Difference between 443 and 8443 HTTPS port
As mentioned, the ports are used for different services and are separated by numbers. The most common numbers used for HTTPS ports are 443 and 8443. But how are they different? The obvious answer is to add the numbers 8 to 443!
However, the real distinction is more complicated than that. Let’s see what each port is for and how they work.
What is port number 443?
TCP local port 443 is the default number used for the HTTPS protocol. It is the primary port that the Internet Engineering Task Force (IETF) recognizes for the HTTPS protocol. Before sending data over the Internet, port 443 uses SSL/TLS certificates to transform plain text into an algorithm. In other words, this browser-dedicated port encrypts data by converting it to an algorithm. Then to send them to the server, port 443 converts the algorithm to the ciphertext to prevent any potential privacy leaks.
Thus, port 443 provides a secure channel for browsers and servers to communicate and transfer data.
What is port number 8443?
The Apache Tomcat server uses port 8443 as an alternative to the HTTPS protocol. Port 8443 enables the web server to open SSL/TLS text services. The major difference between ports 443 and 8443 is how each encrypts data.
Using port 8443 the browser generates a pair of keys for each person. Then hide it in the web browser to authenticate the user and provide a secure communication channel.
Other HTTPS ports
Ports 8443 and 443 are the most common numbers used for the HTTPS protocol. However, there are many other HTTPS port numbers available that provide similar services. You can find a list of registries at the Internet Assigned Numbers Authority (IANA). Here are some of them:
- 832: NETCONF for SOAP over HTTPS
- 5989: WBEM CIM-XML (HTTPS)
- 8243: Synapse non-blocking HTTPS
- 16993: Intel(R) AMT SOAP/HTTPS
- 20003: Commtact HTTPS
Why should I use the HTTPS protocol for my website?
If you are a website owner, you may be wondering if switching to an HTTPS protocol is a good idea. We recommend you do this as soon as possible; We have good reasons for it.
From the very beginning, it gained the trust of users. Even if your clients don’t know the difference between HTTP and HTTPS, using a padlock icon or security warning browser may well leave your website. These days, nothing is more important than online security. Therefore, if you want your site visitors to keep coming back, providing a secure connection is the least you can do.
Additionally, there are many benefits to using an HTTPS protocol, including:
- The HTTPS port protects your users’ data and your website’s data. It provides a strongly encoded channel to send and receive requests over the network.
- It also has a significant impact on SEO. Google has officially announced that using the HTTPS protocol will improve the rank of sites in the SERP (Search Engine Results Page). Currently, over 94% of websites use HTTPS, which gives you almost no chance of competing in the rankings using an insecure protocol.
- Running an eCommerce website is impossible without an SSL/TLS certificate PCI DSS (Payment Card Industry Data Security Standard) requires all websites using online payment services to run on the HTTPS protocol. Otherwise, they do not meet the minimum standards.
Port 8080 HTTP or HTTPS?
The HTTPS protocol transfers encrypted data over port 443. On the other hand, as HTTP transfers data as plain text, port 80 or 8080 can be received by the web server. Port numbers identify each protocol and allow for more organized communication. As a result, port number 8080 is only recognized for the HTTP protocol.
HTTPS TLS or TCP?
One of the most confusing terms about how HTTPS works is TLS and TCP. You are familiar with TCP port 443, which HTTPS uses to transfer data to web servers. On the other hand, TLS is the enhanced version of the SSL certificate. It adds an additional layer of security to TCP ports to send and receive data.
In other words, HTTPS runs over TLS to encrypt data before sending it over TCP port number 443.
Is the HTTPS protocol 100% secure?
Well, in the real world, it’s almost impossible to be 100% secure online. Even the most secure platforms can be hacked, and HTTPS is no exception. Although it offers higher security than its counterparts like HTTP, expert cyber attackers can still access data transferred through port 443.
Conclusion
Hypertext Transfer Protocol Secure or HTTPS protocol provides a secure network for communication and data transfer between a web browser and a web hosting server. It uses SSL/TLS certificates to encrypt the sensitive data of users. In contrast, the HTTP protocol transfers data in plain text and exposes the data to anyone accessing the channel. That’s why you should make sure the site you use runs on an HTTPS port like 443 or 8443 before sharing your information, credit card details, or other online credentials.
