Every internet user shares lots of personal information each day. We do that when shopping online, creating accounts, signing into different websites, etc.
If not properly encrypted, then this information can be spied upon and stolen. SSL provides encryption technology to secure the connection between a user’s browser and the web server.
Each site is issued a unique SSL certificate for identification purposes. If a server is pretending to be on HTTPS, and it’s certificate doesn’t match, then most modern browsers will warn the user from connecting to the site.
The HTTPS in front of the website’s URL and the padlock icon gives the visitor assurance that their information is secure.
