What is SSL? What is an SSL certificate?

The Secure Socket Layer (SSL) is a security protocol that provides a secure channel between two machines operating over the Internet or an internal network. In today’s Internet focused world, the SSL protocol is typically used when a web browser needs to securely connect to a web server over the inherently insecure Internet.

An SSL certificate is a digital certificate that authenticates the identity of a website and encrypts information sent to the server using SSL technology. When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites.
