What is HTTP Protocol?

HTTP stands for Hyper Text Transfer Protocol. WWW is about communication between web Clients and servers. Communication between client computers and web servers is done by sending HTTP Requests and receiving HTTP Responses. 

What is the purpose of HTTP?

The hypertext transfer protocol, abbreviated HTTP, is a system by which computers talk to each other across the World Wide Web. It’s used by computers and smart phones to ask web servers to send the contents of websites and to submit data through online forms. HTTP is text-based, and it’s designed to be readable by humans as well as machines.

How does HTTP work?

HTTP is a protocol used for WWW(World Wide Web) which serve us functional websites, web applications, and web APIs. HTTP clients (internet browsers) use TCP/IP or UDP networking protocol with HTTP to provide us the greatness and usefulness of WWW. 

What is HTTPS Protocol?

HTTPS stands for Hyper Text Transfer Protocol Secure.

Hypertext Transfer Protocol Secure is an extension of the hypertext Transfer Protocol. It is used for secure communication over a computer network, and is widely used on the internet e.g. the browser and the web server. In HTTPS, the communication protocol is encrypted suing Transport Layer Security or, formerly, Secure Sockets Layer (SSL). The protocol is there for also referred to as HTTP over TLS, or HTTP over SSL.

The following figure illustrates the communication over HTTPS:

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encrypted communication and secure identification of a Web server.

Here’s how Verisign, one of the leading SSL Certificate Authority, describes about SSL:HTTPS established an encrypted link between the browser and the web server using the Secure Socket Layer (SSL) or Transport Layer Security (TLS) protocols. TLS is the new version of SSL.

Secure Socket Layer (SSL)

The https is essentially https over SSL. SSL establishes an encrypted link using an SSL certificate which is also known as a digital certificate.



Advantage of HTTPS

One of the main benefits of HTTPS is that it adds security and trust. It protects users against man-in-the-middle (MitM) attacks that can be launched from compromised or insecure networks. Hackers can use such techniques to steal your customer’s sensitive information.

  • Secure Communication: https makes a secure connection by establishing an encrypted link between the browser and the server or any two systems.
  • Data Integrity: https provides data integrity by encrypting the data and so, even if hackers manage to trap the data, they cannot read or modify it.
  • Privacy and Security: https protects the privacy and security of website users by preventing hackers to passively listen to communication between the browser and the server.
  • Faster Performance: https increases the speed of data transfer compared to https by encrypting and reducing the size of the data.
  • SEO: Use of https increases SEO ranking. In Google Chrome, Google shows the Not Secure label in the browser if users’ data is collected over http.
  • Future: https represents the future of the web by making internet safe for users and website owners.
