TOPIC: security spec?

As part of using your solution, we have to undergo a security audit by our host. It\'s because of the credit card processing. Can you be more specific how you handle the credit card information especially when you remember this info when integrating to Community Builder?

1) do you mask the credit card info when displaying card holder data to the last 4 digits?
2) What method of encryption to you use when encrypting the credit card info?
3) do you prevent SQL injection?
4) do you use SSL-128 bit or 40?

Thanks for the info. There are a mirad of other questions, but they\'ll be answered by my host and by me. I really do appreciate your product. There\'s a lot of code in there!
