What is difference between HTTPS , SSL and TLS ?

                  Are you looking for details about HTTPS protocol? Are you also interested in knowing the differences between HTTPS, SSL, and TLS? If so, then you reached the right place. In this article, we will learn more about HTTPS, SSL, and TLS. Let's start.


A) Understand the speed of the data 

               The data sent over the internet is very fast. It is faster than traditional channels such as wires, optic fiber, air. It will not be an exaggeration if we say data send over the internet with speed of light. Even speed of data sent over the internet is fast, but it still has to go through multiple devices during its journey over the network and that is where criminals target data.






B) What is HTTPS?

                The internet consists of distributed client and server information systems. When we access any application using a computer or mobile or any other type of device, ( these devices act as the client ) we send the request to the server. The server can accept or reject the request. If the request is accepted then a connection is created over a specific protocol. In order to establish a communication set of rules which are implemented with the protocol.

                 HTTP stands for Hypertext Transfer Protocol used on the worldwide web(www). This commonly used protocol defines 

                                   1. How data is formatted

                                   2. What type of data is to be transmitted 

                                   3. How the server should respond to the specific command 

                  However, HTTP is not secure as it does not have data encryption and authentication functionalities. In order to achieve security especially transmitting data over the network, Hypertext Transfer protocol secure (HTTPS) protocol can be used.

                                  Though HTTPS is a safer solution for the client and server models, this added security isn't automatic. In order to maintain security standards, we need to purchase SSL/TLS certificates from a trusted certificate authority.


C) What is SSL? 

                The SSL stands for Secure Socket Layer. The internet connections are maintained safely by SSL encryption and decryption method. These connections can be between client to client or client to server or server to server. As SSL is an older protocol, the updated TLS was released in 1999 and it is being commonly used nowadays.






D) What is TLS?

                 TLS stands for Transport Layer Security. TLS is a cryptographic protocol used for achieving better privacy, data integrity, and authentication compared to SSL. It supports stronger, secure cipher suites and algorithms.

                TLS is more commonly used in computer networks, web browsing, instant messaging, email etc.
