When you run an online retail store, it is up to you to provide the appropriate level of security for your customers. You must provide encryption services that will protect all of their personal and banking information from those who would attempt to steal this information. The best possible way to do this is to contract with a certification authority to provide you with complete SSL encryption for your web site.
The Certification Authority Provides You with a Digital Certificate
The digital certificate that the certification authority will provide you with comes with a both a public key and a private key. The public key is the half of your encryption program that is attached to your order page. It takes all of the information entered by your customers and encrypts it in such a way that only you or the third party you have entrusted your orders to can decrypt because you have the private key. This form of security is considered to be the best in the business and is what everyone is looking for when they go shopping online.
