About Security
It is your responsibility to protect your passwords and other confidential data and to
implement security safeguards on your website and in your organization, or to ensure that your
hosting company or internal web operations team is implementing them on your behalf.
IMPORTANT: To enable testing of Payflow Pro, PayPal provides sample transaction scripts
that you customize with your Payflow Pro account information and password.
Because the password is initially stored in the text of the program, it is
vulnerable.
Do not use the test scripts in your production environment. To minimize fraud,
machine passwords should always be encrypted. You must write a program
that encrypts and decrypts your Payflow Pro account password.
