numero = 39242
interpreted = N
texte = I'm being driven crazy by trying to get the encypt and decrypt DNA to work properly. I can get it to work except where the end user is using the AOL or CompuServe browsers. In this case, the decrypt either doesn't work or nothing is displayed.I am trying to protect credit card n=umbers that are stored in a WebMerchant Orders database. We process cards manually and only use WebMerchant to display and manage the orders. On the store site, I put the credit card number into one of the cart headers. Since I can't seem to encrypt and decrypt the card number, I figured I could perform some sort of mathmatical operation on the card number when setting it into a header and do the reverse when displaying the card number in WebMerchant. At least, if someone snags the orders database off my server, the card number won't be usable. Not a perfect solution, but the best I can do now.The problem is that when I perform some [math] on the card number, the result is in scientific notation and the card number doesn't survive the reverse math that I perform in WebMerchant to view it.Any help would be appreciated.Richard Kirsner------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
