If you want to run commercial transactions, or process your website’s data online securely, you need an SSL certificate for your website. Basically, it gives you the valid encryption for the website – and if you ever wondered what is the difference between domains that have http:// or https:// in the URL, this is it: letter S means that it is a secure, encrypted connection. Most common everyday use for the SSL is in the e-Commerce.

SSL stands for Secure Sockets Layer. It is an encryption protocol that provides communication security over the Internet. TLS stands for a Transport Layer Security. SSL is a predecessor of TLS. Both TLS and SSL are using asymmetric cryptography for authentication of key exchange, symmetric encryption for confidentiality, and message authentication codes for message integrity.

What it means to end user – your internet connection is encrypted and secured. That is when you can see a trusted HTTPS marker on the address bar.
