SSL (Secure Sockets Layer) is a technology that performs data authentication and encryption for the data transmitted through the internet connection. This technology encrypts the data that is transmitted between two systems (usually between a server and a client) over internet in order to ensure that the information remains private and safe. This is the time where cyber crimes have increased and if you are using SSL to protect the information on your website, it is important for you to know everything about HTTPS.<\/p>\n

Data can be transmitted between two systems with or without the use of SSL. The SSL port number is an indicator that states whether the connection is secure or not. By default, HTTPS connections utilize the \u2018TCP port 443\u2019 whereas the HTTP connections (not secure ones) utilize \u2018port 80\u2019.<\/p>\n

Commonly Used TCP Ports<\/strong><\/h2>\n

If you are responsible for configuring and managing a web hosting account, it is important for you to know the numbers of common services such as the SSL port. The table given below will help you to get a quick glace on the port numbers and their basic functionalities:<\/p>\n

How Does HTTPS And SSL Work?<\/strong><\/h2>\n

HTTP is a not a separate protocol as that of HTTPS. The fact is that HTTPS works by creating a secure HTTP connection with the use of SSL. Therefore, the protocol stacks for HTTP and HTTPS look alike.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t

A major difference between HTTP and HTTPS is that HTTPS runs on SSL. In order to establish a secure internet connection, it is important to install an SSL certificate on the web server. The SSL certificate validates the organization\u2019s identity for activating the HTTPS protocol. As a result of this, data is safely passed between the web server and the web browser.<\/p>\n

Distinguishing Between Certificates And Protocols<\/strong><\/h2>\n

The \u2018HTTPS protocol\u2019 and the \u2018SSL certificate\u2019 are two distinct but vital factors for establishing a secure internet connection.<\/p>\n
