What is SSL?
By encrypting data communicated over the Internet, it is a mechanism to prevent data tapping, tampering and impersonation. The security of data communication is enhanced by combining secret key cryptography and public key cryptography. Web sites that have been SSLized lead to an improvement in the display order of search results and visitor trust.
Implementation of SSL
Obtain an SSL certificate, install it on the server that operates the website, and change the settings of the WEB server such as Apacche, Nginx.
There are three types of domain authentication, corporate authentication, and EV. Domain authentication is only for domain owner confirmation. In corporate authentication, the existence of the company is verified when SSL is issued, so it is highly reliable. In EV, the company name is displayed in the browser title. EVs are often employed by financial institutions. Domain authentication can use open source SSL available for free, such as Let's Encrypt. There are also hosting companies that offer shared SSL, so if you want to prioritize your budget for the first time you set up your home page, you can also choose a hosting company that offers SSL.
