what is (https)
If you're going to run an online store or an Ecommerce Web site, you will want to ensure customers that the information they give you on that site, including their credit card number, is handled securely. To do this, your site will need to use HTTPS - or HyperText Transfer Protocol with Secure Sockets Layer, or SSL. HTTPS is a protocol to transfer encrypted data over the Web. When someone sends you financial information, social security numbers, or other sensitive data, HTTPS keeps that transmission secure.
