Secure Sockets Layer (SSL) technology encrypts information from a customer's PC to your website. SSL is implemented using what is known as digital certificates that bind an identity to a pair of electronic keys that can be used to encrypt and sign digital information.
A Secure Server ID makes it possible to verify someone's claim that they have the right to use a given key, helping to prevent people from using phony keys to impersonate other users. Used in conjunction with encryption, Secure Server IDs provide a complete security solution, assuring the identity of one or all parties involved in a transaction.

When don't I need SSL?
If you are planning to use an electronic banking gateway that takes the customers' credit card information at their own site, then you don't need SSL on your own web host. When the person gets to the point of needing to enter payment information, the button goes to an SSL protecting electronic gateway.
VP-CART supports many of the most popular electronic gateways. See our description of electronic gateways.
Do I Need SSL?
If you are planning to take credit card information using standard VP-CART facilities then you probably do. Internet buyers will only trust their credit card information if they know they are securely transmitted.
But you may not need to buy a digital certificate. Many web hosting companies let you use their digital certificate for free or for a small charge. Check with your web hosting company.
