What is SSL and do I need it?

SSL (Secure Sockets Layer) is the standard for secure transactions on the web. You'll recognize it by websites running on https:// instead of http://. To use it, you need to buy an SSL Certificate and add it to your hosting environment. Some hosting providers offer it as a service, whereas others just point to third parties offering SSL Certificates, like for instance, RapidSSL (https://www.rapidssl.com) or VeriSign (http://www.verisign.com), currently owned by Symantec.

We'll not offer a complete set of instructions on using SSL here, which is beyond the scope of this book. However, it is good to know when you'll need to pay attention to SSL. There can be two reasons to use an SSL certificate:

  1. You are accepting payments directly on your website and may even be storing credit card information. In such a case, make sure that you are securing your store by using SSL. On the other hand, if you are only using third parties to accept payments, like for example, Google Checkout or PayPal, you do not have to worry about this part. The transaction is done at the (secure part of the) website of your payment service provider and in such a case you do not need to offer SSL.
  2. However, there's another reason that makes using SSL interesting for all shop owners: trust. Regular shoppers know that https:// connections are secure and might feel just a bit more comfortable in closing the sale with you. It might seem a little thing, but getting a new customer to trust you is an essential step of the online purchase process.
