　　What is an SSL certificate?

An SSL certificate is a digital certificate, similar to an electronic copy of a driver's license, passport, and business license. Because it is configured on the server, it is also known as an SSL server certificate.

An SSL certificate is an SSL protocol that is issued by a trusted Digital certification authority CA (such as GlobalSign) after authenticating the server, with server authentication and data transfer encryption.

The SSL certificate is designed and developed by the Netscape Communication Company by establishing an SSL secure channel between the client browser and the Web server (Secure Socket Layer (SSL) security protocol. This security protocol is primarily used to provide authentication to users and servers, to encrypt and hide transmitted data, to ensure that data is not changed in transit, that is, the integrity of data, has become a global standard in this field. Because SSL technology has been built into all major browsers and Web server programs, it is only necessary to install a server certificate to activate the feature. That is, it can activate the SSL protocol, and realize the encrypted transmission between the client and the server, which can prevent the leakage of the data information. The security of the information is guaranteed, and the user can verify through the server certificate whether the website he visited is true and reliable.
