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?
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.
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:
• 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.
|80||HTTP (HyperText Transfer Protocol) – used to transfer web pages|
|443||SSL – used to transfer web pages securely using encryption (Default port for https)|
|21||FTP Protocol (Control) – used for FTP commands and Flow control|
|990||FTPS Protocol (Control) over TLS/SSL|
|22||SFTP/SSH (Secure Shell) – used for secure logins, file transfers and port forwarding|
|3306|| MySQL |
|110||POP3 – Incoming (used for retrieving emails)|
|995||POP3 SSL – Incoming (encrypted transmission)|
|143||IMAP4 – Incoming (used for retrieving emails)|
|993||IMAP4 over SSL – Incoming (encrypted transmission)|
|25,80,3535||SMTP – Outgoing |
|465||SMTP SSL – Outgoing |
|2082||cPanel TCP inbound|
|2083||cPanel SSL TCP inbound|
|2086||WHM TCP inbound|
|2087||WHM SSL TCP inbound|
|2089||WHM SSL TCP inbound|
|2095||Webmail TCP inbound|
|2096||Webmail SSL TCP inbound|
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.

Certificate and protocols are two different things but both are necessary to providing secure internet connections.
In order to encrypt the information, you need to configure your certificate on the web server and set it up.
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.
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.
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.
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:
| Hypertext Transfer Protocol||Hypertext Transfer Protocol Secure|
| Security|| Security is Low, Data can be stolen easily ||Prevent from hackers with best Encryption standards|
| Port|| Uses port 80 by default ||Uses SSL port 443 by default|
|Start With|| http://||https://|
| Used For || Best suitable for Blogs etc. ||Secured online payments and confidential information. |
| Protocol || It uses TCP/IP.||It also runs over HTTP but uses a TLS / SSL encrypted connection.|
|Domain Name Validation|| No SSL required ||It requires an SSL certificate.|
|Data encryption||No data Encryption||It uses Data Encryption.|
According to TCP/IP model, HTTP protocol stack will be like this:
HTTPS stack has the following:
|Layer (OSI Model)||HTTP Protocol Stack|
HTTPS Protocol Stack
| Security Layer|| || SSL (TLS)|
| Transport Layer|| TCP|| TCP|
| Network Layer|| IP|| IP|
|Data Link Layer||Network Interfaces||Network Interfaces|
