Nope. Because unless you write a complicated and potentially insecure
script to decrypt the card, you have to store the credit card number
in the clear on the disk. We don't do that. If you want to figure it
out yourself and do it, so be it, but we certainly won't help.
One way to do it is to use https and pass a GPG pass-phrase that way
every time, but that is not really secure either.
We encourage the use of GPG/PGP as the means of getting credit card
numbers. That, you can do with Interchange. In fact, it is even quite
convenient with a mailer like Eudora, which only prompts you once no
matter how many emails you open in the same session.
