I am using a script which was posted here to take orders on my site and post credit card details along with billing information to Authorize.Net - I am using Net::SSLeay to do this, but I would like to ask a few questions from you wise ones:
- In this script the cc number is stored in $cc as any other variable would be. I am paranoid about the security of these details though while they are on the server, I'm fairly confident in the transfer as they are done using Net::SSLEay to a SSL secured server.
My concern is, when this number is stored in the variable how long is it stored in the system memory? Is there anyway to prevent this from happening?
