FDF Security

I have been trying to convince my Yacht Club to purchase Acrobat and
use Adobe forms to pre-register entrants for our races. My question is, "How secure are FDF files"?
Are they sufficiently secure to transmit credit card data and if not what must one do to make them so.

No, not by them selves. If you have a server that supports SSL you can submit the FDF this way. You can also submit or email a whole PDF that is secure.

Thank you very much. I suspected as much.

Can an Acrobat Reader user submit a whole, secure PDF?

Yes, but the PDF has to be enabled for save rights first, which you do with Acrobat 8.

This is one of those tricky operations that has to be done just right, i.e., applying both Reader enabling and security. I'm not exactly sure of the ordering, but I believe that you have to apply security first, but not save, Then apply the reader rights, which saves the file and applies the security.

Thank you.

Looks as though I have a little more learning to do. I was able to enable the form for Reader but could not figure what security setting to use. We woudl hope to post the form on a web site and allow people to register using their Visa card. I guess this would require working though the server whoch woudl probably not give us any significant advantage over the secure system we are now using.

Hi Thomp,

It's me again. I have successfully tested the submitForm() javascript function to submit the whole pdf to a server through http. However, when I tried using https for secure submit, it failed.

You previously mentioned that the form needed rights enabled and apply security. I have rights enabled the form using ReaderExtensions but don't know how to apply security. Could you please give more detail information. Many Thanks.

I don't know if HTTPS will work with Acrobat. I've heard varying reports but haven't tried it myself.

Applying security is very easy, look it up in the Acrobat Help. But this is one trick when applying security to a rights enabled PDF. Apply the security first, but do not save the file. Then rights enable it.
