The full name of SSL connection is SSL digital certificate, which can use high-strength signature algorithm and server-side encryption protocol to complete https encrypted transmission between Web access client and server. Certification bodies should strictly and reliably verify the information of certificate applicants, so as to make the website credible and prevent hijacking, tampering and monitoring. Provide authentic, effective and safe website content for website visitors.

SSL certificate plays the role of encrypting and transmitting data between visitors and websites, and prevents sensitive data such as account numbers, passwords and credit cards from being stolen during transmission. Basically, websites with account passwords need SSL certificates, and SSL certificates can also prevent transmission data from being tampered with. Once the transmitted data is tampered with, it may be hijacked by inserting advertisements, dangerous codes or website traffic, allowing users to visit other websites.
