What is HTTPS and Why You Need to Implement It
First things first. HTTPS is better, more secure and more reliable than HTTP. As you probably know, the Hyper Text Transfer Protocol works as a taxi-driver for data, moving it around the Web.
So, what is the difference between HTTP and HTTPS? Is it merely an "S" at the end of that word or is there something more to it than meets the eye? The true power of HTTPS is hidden in the meaning of that single "S" since it stands for secure.
When you adapt HTTPS, you get not one but three key layers of protection. Hyper Text Transfer Protocol Secure or HTTPS protects your data. To do so, HTTPS focuses on encrypted data, authenticity and integrity.
Each of the three bring significant security improvements, whereby data integrity data encryption adds protection to information by encrypting it, authentication prevents any possible interception of data and integrity blocks an unknown third party and disables any unwanted data modification.
The first users of HTTPS were banks, eShops, ecommerce sites, credit card companies and online casinos, which comes natural as these businesses deal with confidential data and money transactions.
However, ever since Google has started to use HTTPS as a ranking signal, every website owner around the globe got an additional reason to migrate from HTTP to HTTPS . In addition, updates such as HTTP/2, which improve the speed of your website are supported in certain browsers only over HTTPS.
