SSL Cerificate Import / Export
In short, SSL Certificate is an authentication between web browser and host. A comprehensive
Certificate includes corporation name, web site name, users account, digital key and validity
date of certificate. Web browser will request the web site to show digital certificate when the web
browser requests to use SSL mode (https://). If web browser decides to accept the digital
certificate, all data between the web site and browser will use certificate digital-key encryption
to avoid hacker to access the data.
SSL certificate includes public-key and private-key. Public-key is used to encrypt data while the
private-key is used to decrypt. When the web browser connects to SSL network (http://), SSL
protocol will verifies server and client identities and creates a encryption method with public key.
Then, the SSL will start a security process to protect the privacy and data integrity.
