Realize website https access, anti-hijacking, anti-tampering, compatible with various PC and mobile browsers, and strengthen website data security.
An SSL certificate (Secure Sockets Layer Certificate) is a digital certificate used to encrypt communications between websites and users. It uses public key encryption technology to ensure the security and integrity of data transmission. The main function of the SSL certificate is to realize the HTTPS access of the website. By using an SSL certificate, a website can establish a secure HTTP connection to ensure that the data transmission between the user and the website is encrypted and prevent third parties from stealing sensitive information. In addition, SSL certificates can also prevent websites from being tampered with and hijacked, and enhance the security of website data.

There is a close relationship between SSL certificates and HTTPS. HTTPS (Hypertext Transfer Protocol Secure) is a secure HTTP protocol encrypted by using an SSL certificate.
SSL certificates are used to encrypt and authenticate HTTPS communications. When a website uses an SSL certificate, it binds the public key to a specific domain name and verifies the authenticity of the certificate through a digital signature. When a user visits a website that uses HTTPS, the browser performs a handshake with the server and uses the public key of the SSL certificate to encrypt the communication. In this way, the data transmitted through the HTTPS protocol will be transmitted between the user and the server in an encrypted form, preventing third-party eavesdropping and tampering.
Therefore, it can be said that the SSL certificate is the basis for HTTPS secure communication. It ensures that the data transmission between the website and the user is encrypted, protecting the privacy of the user and the security of sensitive information. At the same time, the SSL certificate is also a way to verify the identity of the website, to ensure that users establish a secure connection with the correct website, and to prevent attacks from phishing and counterfeit websites.
To sum up, the SSL certificate provides security and reliability for the HTTPS protocol through encryption and verification mechanisms, ensuring that users' data transmission on the Internet is protected.
