If I had had mcrypt available in PHP when I first built this, I would have just used this facility. But the first server I was on didn't have mcrypt, so I rolled my own implementation of TEA. > 2) What info do you encrypt?

I encrypt the information that Authorize.Net requires for a batch transaction, along with few additional pieces of information (e.g., a unique transaction #, cardholder name). > My concern is being sure I only keep a list > of valid and approved credit card numbers, not > any that are declined.

But, that's no problem, I just retain it in the PHP page & use it if the authorization succeeds.

Just update the DB by hand. It's fast & easy. > Monty -- JR
