SSL (Secure Sockets Layer) is a way of establishing an encrypted connection between a web server and a browser. This ensures that all communication between the web server and browsers remain private and integral. This is important for online security, especially when you are handling sensitive or confidential data.
When you have an SSL connection it is displayed with a padlock or some other indication that your connection is now secure. On a more technical level what it actually does is encrypts, making a direct private connection like a funnel where everything that is sent up and down between you and that website is encrypted.
Without SSL solution, all data is sent and relayed through a number of different servers on the internet, all in clear text, so there are opportunities anywhere to “sniff the packets“. If someone can read all those packets of data between you and whatever website you are communicating with then they can collect passwords and other sensitive information.
This becomes very important when you are actually connecting to your bank or anywhere else where you are providing personal and private information. So https or Secure Sockets Layer is an important tool or part of the internet.
