Submit credit card info using Session()

Hello,

For security purposes we need the ability to submit the credit card information to Authorize.net without first storing the credit card info in the database. We cannot have credit card information stored within the product database even for a second. I had thought that using session variables would probably best solve this issue however when I try to edit where I think would be appropriate to accomplish this (CTp.asp) I notice that the file is encrypted so I cannot edit the code here. Does anyone know how I can accomplish this or any other way that the credit card information can be submitted to Authorize.net without storing in the database first? Thank you.
