What is the difference between HTTP and HTTPS?

I know many would have wondered what really the difference between HTTP and HTTPS is. Well in this article we made attempts at answering that question with the aim of giving you a better understanding of both HTTP and HTTPS and how they function.

What is HTTP?

HTTP stands for Hypertext Transfer Protocol. It is the set of rules for transferring files (text, image, sound, video and others) on the World Wide Web. It is a structured text which uses hyperlinks between nodes containing text. It provides the rules that govern how files are transmitted to the screen from the webserver via your browser.

What is HTTPS?

HTTPS stands for Hypertext Transfer Protocol Secure. It is the addition of extra security known as SSL (Secure Socket Layer) and TLS (Transport Layer security) both sometimes referred to as SSL. It is the use of encrypted codes to send information back and forth between the sender and recipient of any information on the World Wide Web.

Both the TLS and SSL protocols use what is known as an ‘asymmetric’ Public Key Infrastructure (PKI) system. An asymmetric system uses two ‘keys’ to encrypt communications, a ‘public’ key and a ‘private’ key. Anything encrypted with the public key can only be decrypted by the private key and vice-versa.

WHY HTTPS?

All communications sent over regular HTTP connections are in ‘plain text’ and can be read by any hacker that manages to break into the connection between your browser and the website. This presents a clear danger if the ‘communication’ is on an order form and includes your credit card details or social security number. With a HTTPS connection, all communications are securely encrypted. This means that even if somebody managed to break into the connection, they would not be able decrypt any of the data which passes between you and the website.

ADVANTAGES OF HTTPS OVER HTTP

  • Better site security and less hacking risks
  • Customer information, like credit card numbers, is encrypted and cannot be intercepted
  • Visitors can verify you are a registered business and that you own the domain
  • Customers are more likely to trust and complete purchases from sites that use HTTPS
