SSL certificates have become a necessity nowadays. Let's explore why they exist and how to use them in this article. SSL certificate is used to encrypt traffic between the server and visitor's browser, preventing data interception during transmission. Encrypted traffic is called HTTPS (Hypertext Transfer Protocol Secure), which is a secure connection. Unencrypted traffic is HTTP (Hypertext Transfer Protocol), an insecure connection.
Website pages consist of text, pictures and videos. The text content of the site is usually taken from the database. All these files and databases are located on a special computer - a server. When we open a site, the server generates a page, and our browser downloads the finished page and files from the server and displays it all in the form that is familiar to us. The server can be a home computer, but it must work around the clock, without interrupting the Internet connection, and special server programs must be installed on it. You also need protection from hacker attacks and powerful enough hardware to support several thousand users at the same time. Organizing a server is difficult and expensive, so most often site owners buy hosting. Hosting is a service for storing files and website components on a server. It is provided by hosters: they rent out server capacity. The main task of hosters is to ensure that the resource operates around the clock.
