HTTP (HyperText Transfer Protocol) — a protocol for transmitting data, such as HTML documents. The HTTP protocol underlies the exchange of data on the Internet — using this protocol, users receive information from websites.
However, the HTTP protocol does not provide any mechanisms for protecting user data. Therefore, do not trust HTTP sites with sensitive information. Imagine that you want to make a purchase on a site that runs over the HTTP protocol. You have filled in all the fields necessary for the purchase and clicked the “Pay” button. The browser sends your data to the server. At this point, the hacker can intercept information (such as passwords, personal data and bank card number).
With the goal of online security and minimizing the incidence of Internet fraud, most sites switch to the secure HTTPS protocol.
