SSL stands for Secure Sockets Layer. It is an internet protocol for securing data transfer between a user’s browser and the website they are visiting.
Every internet user transfers information when they visit websites. This information can often be sensitive like payment details, credit card information, or login credentials.
Using the normal HTTP protocol means this information can be hijacked by hackers. This is where SSL or HTTPS comes in.
Websites using SSL need a SSL certificate issued by one of the recognized certificate issuing authority. This certificate is verified and highlighted in user’s browser address bar with a padlock sign and HTTPS instead of HTTP.
