Certificate: An SSL certificate is a digital certificate that authenticates a web site’s identity and enables an encrypted connection. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser.
Private Key: Your private key is the single most important component of your SSL certificate. It’s what gives you the power to authenticate your website to internet users, helps to enable encryption, and prevents others from impersonating you.
