SSL certificate is a type of digital certificate, similar to electronic copies of driver's licenses, passports and business licenses. Because it is configured on the server, it is also called an SSL server certificate.

The SSL certificate complies with the SSL protocol and is issued by a trusted digital certificate authority CA after verifying the server's identity. It has server identity verification and Data transmission encryption function.

Secure socket layer (SSL) security protocol is designed and developed by Netscape Communication Company. (Recommended learning: web front-end video tutorial)

This security protocol is mainly used to provide authentication for users and servers; to encrypt and hide the transmitted data; to ensure that the data is not transmitted during transmission. What was changed, data integrity, has now become a global standard in this field.

Since SSL technology is built into all major browsers and WEB server programs, the feature can be activated by simply installing the server certificate

The SSL certificate is passed in the client browser Establish an SSL secure channel with the Web server, that is, through it, the SSL protocol can be activated to realize the encrypted transmission of data information between the client and the server, which can prevent the leakage of data information and ensure the security of the information transmitted by both parties.

It is a digital information file used to mark and prove the identity of both parties in network communications. , the concept is similar to a driver’s license or ID card in daily life. Digital signatures are mainly used for secure online electronic transactions such as sending secure emails, accessing secure sites, online bidding and tendering, online signing, online ordering, secure transmission of online official documents, online office work, online payment, online tax payment, and online shopping.

A valid and trusted SSL digital certificate includes a public key and a private key.

The public key is used to encrypt information, and the private key is used to decrypt the encrypted information.

So when the browser points to a secure domain, SSL will simultaneously confirm the server and client and create an encryption method and a unique session key. Generally speaking, digital certificates issued by the CA industry are different from the way domestic browser companies compare domain name information and adopt more stringent corporate and ownership verification to establish a more trustworthy operating environment for the e-commerce environment.
