PDF Document Password Handling

This would be a great plug-in if it included a way to handle protected PDF files that require a password to open.

I typically set a common password to limit redistribution of my PDF files. If I did not do this, anyone could just keep distributing our paid files forever, without limitation. Using a single global password means they must distribute both the file and the password. This makes it easier to identify the files if they ever show up on some download lists.

Anyway, I've requested this before and the author seems to have deleted the request. Not sure if he implemented the request or, as in the past, is just blowing us off.

It could work very simply, just add a form field for the document that could be included in the receipt email.

Please advise if this has now been implemented in some way.

Hi

I am sorry but this feature is not implemented yet. And to be honest, I don't know whether it is possible or not to add password protected into a PDF file using PHP, so maybe we will need to do some research. Have you seen any software (which built in PHP programming language) has this feature ?

Tuan:

It's very clear that you STILL don't understand how PDF document passwords work or even what I'm asking.
THis is an incredibly easy thing to implement and it DOES NOT require you to add anything to the file "using PHP".
Let me try to explain one more time:

1. When I create a PDF file, Adobe allows me to set a security password for the file. It's ONE static password. It doesn't change for different users, its the same global password for ALL users who want to open that PDF. This is a common function of Adobe's PDF creation software.

2. So, when I sell a password protected PDF, all I need to do is deliver that one password along with the PDF.
I realize someone could put the password in a text file then zip it together with the file, but for 99% of honest people, that's too much bother.
I consider this "pretty good security" that's all.

3. So, once the person buys the document, in the receipt email, I want to be able to put a line that says: "The password required to open this document is: %password%" Simple as that. It require no modification of the document or anything.


How could you implement this you ask?
In the document area, add a single field for the document password. That same password would then be added to the receipt email as described above.

Do you now understand how incredibly easy this would be to implement?

In fact, the only thing you would need to do is to add a small text box to server as a "product message" that would be sent along with the sales receipt. It HAS to be on a document basis, so each document would have it's own "product message". In this text field, the seller could include any special instructions. Once the buyer makes a purchase, that text is included as special instructions and can contain the DOCUMENT PASSWORD.

I figure this change would take all of an hour to add to the script. Remember, it's DOCUMENTS SELLER, not software seller or something else. There is a very nice FREE Wordpress plugin by pippin that already does exactly this.
