What Is An SSL Port? An Ultimate Technical Guide To HTTP, HTTPS And SSL

7 min read

When we transmit or receive the data from the internet, our first priority is the security of data. For this special task, Secure Sockets Layer (SSL) is a technology that performs the encryption and authentication of data to keep the internet connections secure. Nowadays, cybercrimes are increasing day by day and SSL stops the reading or changing the confidential information. If you are using the SSL then it is equally important to know about HTTPS. The term SSL Port is used to identify whether or not your connection is secure.
In this article, I have covered maximum topics related to the securing internet connection, common ssl ports, TCP ports, difference between HTTP and HTTPS, how to secure your connection with the help of SSL and what is the HTTPS port?

What is SSL Port?

Every port on the internet is used for a specific purpose. Whenever you access any online shopping store or another website from your browser, you are experiencing the communication between your laptop and server (on which the shopping store is hosted) with or without SSL. The SSL port is used to indicate either your connection is secure or not.

How you can find your connection to a website is secure or not?

The formula is simple, just look in the address bar where the web site’s URL has appeared. The URL starts with either HTTP or HTTPS: Hypertext Transfer Protocol (HTTP) is the indication of unsecured protocol that uses the port number 80 and Hypertext Transfer Protocol Secure (HTTPS) shows your connection is secure. Now you are thinking about a question “what is the default TCP port for HTTPS?” port number 443 is used as a default. You can view difference in the picture given below:

If there is no secure connection, you will see the following:

List of Commonly Used TCP Ports

Port Number 0 to 1023: This range of port numbers is assigned to specific server service by the Internet Assigned Numbers Authority (IANA) and these ports are well-known ports.

• Port Numbers 1024 to 49151: This range of port numbers are known as semi-reserved and used by application developers or any other organization for a particular service with the registration of IAMA.

• Port Numbers 49152 to 65535: This range of port numbers are used by client programs and application developers can use any of these ports freely.

Understand the common services and their port numbers if you are going to configure or manage web hosting accounts. The table given below will help you to quickly go through the port numbers and their functionalities.


Port Number Function
80HTTP (HyperText Transfer Protocol) – used to transfer web pages
443SSL – used to transfer web pages securely using encryption (Default port for https)
21FTP Protocol (Control) – used for FTP commands and Flow control
990FTPS Protocol (Control) over TLS/SSL
22SFTP/SSH (Secure Shell) – used for secure logins, file transfers and port forwarding
3306 MySQL

What is The Difference Between HTTPS and SSL?

There is no major difference between HTTP and HTTPS except the SSL. HTTPS is a HTTP protocol that delivers data using the secured SSL. Secure Sockets Layer is a protocol that works on the top of HTTP to deliver security. It is important to install an SSL certificate on the web server for secure internet connection. It validates the identity of the organization by activating the HTTPS protocol and data is safely passed between web server and browser.

What is the Difference Between Certificates and Protocols?

Certificate and protocols are two different things but both are necessary to providing secure internet connections.

  • HTTPS protocols is like a physical structure which is used to provide a secure medium to travel encrypted information between two points in a securely manner.
  • An SSL certificate is used to encrypt the information that will be shared on HTTP structure.

In order to encrypt the information, you need to configure your certificate on the web server and set it up.

What is The key Difference Between TLS and SSL?

The SSL is originally developed by Netscape in 1995. However, the TLS is a different thing but uses same protocols and techniques to fulfil the security risks of today’s world. TLS is recommended for a higher level of security because it uses a stronger encryption algorithm but it is also known as SSL.

What is The Importance of SSL Port?

It is necessary to configure a SSL certificate form a range of SSL Certificates on your web server to get a message “connection is secure” (HTTPS) in the URL address bar. This is the permission of secure connection between a client and server. In this digital world where the users and online businesses are increasing day by day, the number of hackers are also trying to get your confidential information for misuse. So, it is a vital for any secure website to install a SSL encryption to protect your useful information form malicious attacks.

What are the Benefits of Using SSL?

  • Faster Loading Speed than HTTP
    Nowadays, speed matters the most for good online experience and compete with the top industry competitors. Proactive people always try all different techniques to boost up their website’ speed. Every user is urgent in this busy life and can’t wait for loading and moves on another website. Use of HTTPS is crucial factor to be implemented when the creative people consider all the optimization factors. Every website having HTTPS will load the website faster and saves the time. In short, it is good marketing strategy that every user will be visiting our website again and again when he needs to buy anything, so it is very important for good user experience.
  • Boost your Rankings and Increase Brand Value
    To become a well-renown and popular business brand on the internet, the website ranking the key requirement. The better you rank in Google the better ROI and maximum number of users. Maximum number of users are equal to maximum business from the internet. Your website rank higher in the SERP results if there is TCP port of HTTPS is used and any SSL certificate is installed.
  • Kick Out the Hackers with Strongest Encryption
    With the increasing risk of hacks, there is a number of encryption algorithms are used to deliver an exceptional quality of data encryption. Advance level algorithms like DSA, RSA and ECC are used to encrypt the personal and confidential data.
  • PCI Compliance for Secure Online Payments
    For the ease of users’ online shopping, there are number of payment methods are available to deliver peace of mind. When it comes to the online payments, you need a third party known as Payment Card Industry (PCI) and follow the standard strictly for compliance with its requirements. It is a necessary part of PCI compliance that you must have HTTPS implemented.
  • Build Audience’ Trust
    Most of the people don’t want to share their personal information to a website which is running on HTTP. The users will be more comfortable with a website having SSL certificate. It is stronger signal about the privacy of their information.

Where to Get SSL?

There are a number of different SSL certificates available to choose more appropriate one that fulfills your requirements. Check our latest plans and get wonderful discounts.

What are the Differences Between HTTP and HTTPS?

If you are using the HTTP protocol any hacker can esily hack because your information is open and acccessible. In case of HTTPS, you information can’t be changed because it is encrypted. As you can see in the picture given below:

Features of HTTP

  • Pages are stored in cache, so that they can be accessed quickly
  • Cross-platform porting
  • No runtime support is compulsory
  • Available for firewalls!
  • Not Connected-Oriented

Features of HTTPS

  • Redirect from HTTP:// to HTTPS://
  • Allow secure e-commerce transactions
  • SSL technology protects confidential data and build trust
  • SSL contains unique authentication information about the certificate owner.
  • Web Push notifications only apply to HTTPS.
  • PWA (Progressive Web App): It enables to convert your website as Playstore mobile App in Android.
  • GetUserMedia: If you are using HTTP, you cannot allow the user to use the camera or microphone.

According to TCP/IP and OSI Model

According to TCP/IP Model:

HTTP protocol stack

According to TCP/IP model, HTTP protocol stack will be like this:

  1. HTTP – Application
  2. TCP – Transport
  3. IP – Network
  4. Ethernet – Network Interface

HTTPS protocol stack

HTTPS stack has the following:

  1. HTTP – Application
  2. TLS (SSL) – Transport Layer Security
  3. TCP – Transport
  4. IP – Network
  5. Ethernet – Network Interface
