HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP Secure) are two different protocols for transferring data across the internet. The major difference between the two protocols is the fact that HTTPS employs SSL/TLS for encryption of the data that is being transmitted, whereas HTTP does not.
If a user is on the website via HTTP information, the data that is entered into forms or sent via the website is transmitted as plain text. This means it could be easily read and intercepted by a third party. This includes passwords as well as credit card numbers as well as other sensitive information.
HTTPS, On the other hand, is a way to secure the information that is transferred, making it harder for anyone to read and intercept it. This additional security is made through an SSL/TLS certification that establishes an encrypted connection between the user’s browser and the site.
It is highly recommended to utilize HTTPS on any website which requires users to input sensitive data, like passwords for login and credit card information. Additionally, it provides greater security for all data that is transmitted to your site.
Furthermore, Google has announced that it will provide an increase in the rank of HTTPS sites that are HTTPS-enabled as an aspect of efforts by the company to help promote the use of a safer internet. In sum, HTTPS is recommended over HTTP since it offers security when sending data via the internet while also protecting the private information of the users as well as your site.
