What Is SSL?
SSL Definition
Short definition:
SSL (Secure Sockets Layer) is a technology that protects user information by encrypting the data being exchanged between the web browser and the webserver.
Extended definition:
The SSL or also mentioned as TLS (Transport Layer Security) which is its predecessor, is a cryptographic protocol that provides security for communication over a computer network. The protocol is commonly used in applications such as instant messaging, email, and voice over IP, but its use in securing HTTPS remains the most general use.
When enabled, the SSL or Secure Sockets Layers technology transforms an HTTP site into an HTTPS site. HTTPS sites have a green padlock sign next to their website addresses in the browser. This sign shows that sites provide a secure connection.
When you open a website, your browser will automatically check for an SSL certificate. If it is valid and up to date, the session will proceed normally. But in case the check doesn’t pass, then users will be warned that the connection is not private.
