Password Protected PDFs in Digital Editions

Hello,
Is there a version of Digital Editions into which it is possible to add password protected PDFs? My apologies if this question has been posted before, it doesn't seem to be possible to search within a specific forum.
Thanks.

There is no current version of Digital Editions that supports opening PDF files which require a password to open.

How to password-protect PDFs to prevent editing?

I'd like to print a PDF from within Word and password protect it to prevent editing of the PDF. I don't need encryption (one of the default PDF services), I need password protection against editing.
If there's a way to do this without resorting to Acrobat Pro, it would be ideal.
Anyone? Anyone?

Edit multiple password-protected PDFs using Photoshop CS5 Javascript scripting.

Good Evening,
Situation: I have a huge stack of PDF files and I'm using Photoshop CS5 to slice out previews and other things automatically, using a self-built javascript. Some (100+) of these PDFs are password-protected. I have the password to these files.
Problem: Every time the script tries to open one of the protected PDFs it will open a popup, stop the whole process and wait for the user to input the password.
Question: Is there a way to add the password to the open command of the app.open(...) function? Or more simply put, can this be fully automated?
What I looked at so far: "PDFOpenOptions", "app.open(...)", the javascript reference("photoshop_cs5_javascript_ref.pdf") in general.
Basic Example code:
var f = new File("path to some password protected PDF");
var d = app.open(f); //this will trigger the password popup
doSomethingWithMyDocument(d);
d.close(SaveOptions.DONOTSAVECHANGES);
Any help would be greatly appreciated. I have access to Photoshop CS6 as well, if that somehow solves the problem.
If I'm looking at a dead-end, feel free to tell me too.

It is possible to do that via Scripting.
If you are unable to create such a Script maybe you should look up the chapter »Creating data-driven graphics« in the documentation.

Open password protected PDF in website

Hi,
I hope someone can help me. Greatly appreciate it.
My website has PDF documents that's available for registered users to view online (through my site) only.
Currently, I can't find any solutions to prevent users from downloading/"save-as" the PDF doc in their local drives, so I'm thinking of password-protecting these PDFs. This will ensure that they'd not be able to view the PDFs even though they download it and save-as local.
However, how do I open these password-protected PDFs on my site?
When I point/redirect to these PDFs, it will prompt for password.
It'd defeat all protection intent if I were to give the password to the user to enter, right?
Example:
1. Response.Redirect("mySecuredPdf.pdf")
2. The browser will then prompt user for password.
What can I do in the CodeBehind to enable the server to OPEN the pdf, and at the same time, pass the correct password to the viewer to open without prompting?
I cannot remove password, because I want to prevent users from downloading and then opening it later, or redistributing the file.
btw, i'm using ASP.NET.
Please help.

There's a similar thread in the Acrobat Windows section, and the answer is the same - only a DRM system with a client UI (such as Adobe Digital Editions) can restrict the *use* of a file. You cannot prevent the client downloading and saving it, as otherwise they can't see it on their screen. The page you're reading now is not on a computer at Adobe - it's on yours.
> What can I do in the CodeBehind to enable the server to OPEN the pdf, and at the same time, pass the correct password to the viewer to open without prompting?
I think you're getting the flow a little backwards - the PDF is 'opened' by the client, using their copy of Adobe Reader (or whatever). The webserver has nothing to do with the process other than blindly sending the file's 1s and 0s down a wire, so can't do anything to directly control the client's desktop applications.

Password protected PDF in iBooks not displaying

I loaded a password protected PDF into my iTunes library and then synced it with iPad (4th gen iOS 6.1.3). I see the PDF in iBooks on the iPad and when I click on it, it prompts for the password. I input the password and PDF "opens" but it's just the blank grey screen showing page 1/1 (it's supposed to be a 79 page document). Any ideas? I took the password off the document and loaded that one into iTunes then my iPad and it displays just fine. I did this same sequence with a different document and with the password it didn't display and without the password it did display.
If there is an issue with iBooks, any way to sideload this into Adobe Reader, or somehow "Open in" Adobe Reader from iBooks?
Thanks
Dan

It looks like this issue may be limited to files that have been set to restrict the user's ability to print or edit the document (even after a password has been entered for viewing). I found that a password-protected PDF could be viewed in iBooks, but after I added the print restriction, I had the same problem you reported.

Password-protected PDF demands password in triplicate

I'm having problems with a password-protected PDF (created in Acrobat Pro 8 ) which opens fine with a single entry of the password when downloaded but when website visitors try to open the form directly in their browser it keeps asking for the password and will only open on the third password attempt (by when most visitors will have given up on it). Could you please tell me what is causing this phenomenon and whether I can fix it? TIA.

How to display in browser a password protected pdf file I created?

I created a password protected pdf file.
I want to display the file in browser so that viewers can only view it online.
It is better that viewers cannot download it.
But I donot know how to prevent viewers downloading the file.
Since the pdf is password protected, viewers don't have the password even they download it.
But how can I display the password protected pdf file in browser when I know the password?
Or is there a better to just viewers see the pdf file online and prevent them from downloading and printing it?

Any file on the web has to be copied to the local machine in order for the file content to be presented to the viewer. That's how the "www" is built. So, to make use of your web based PDF the file has to be downloaded to the local machine. This might be to the local machine's temporary internet / browser cache or (via a 'save this to my computer') to some other location on the local machine's HDD. Bottom line -- web based files get downloaded this is the case for protected file or a non-protected file.
Be well...

How to open a password-protected PDF in Safari on iPad(3)?

I have some password-protected PDFs available on my public-facing website (hosted by MS Office365) that I'm unable to open in Safari on my iPad(3). When attempting to open these files using Safari on my iPad, I receive a grey screen with no presentation of the Adobe Reader "insert password" dialogue box. I do have Adobe Reader installed on my iPad. These PDFs do open on my PC with both IE9 and Safari. I can also open these PDFs on my iPad independent of using Safari. And, I have some non-password-protected PDFs on my website that open using Safari on my iPad. The problem seems to be uniquely associated with the combination of 1) a password-protected PDF, 2) Safari, and 3) the iPad(3). Does anyone have a solution to this particular situation?

Need to recreate a password protected PDF but can't unlock origional

I have a password protected PDF protfolio that I need to recreate but no longer have the origional password for. I could just write a new PDF, but so much time was spent creating the origional. Is there a way to save a copy and then re-apply the password security?

I want to add that the pdf password unlock programs usually are easier to break the permission password for you to copy, print and edit with corresponding tools. But to crack the open password it's more difficult and if your file is protected by this kind of pdf security, you may have to type word by word from scratch.....

Mavericks Preview Opens Password Protected PDF?

I exported a image in CS6 Illustrater as a pdf. I saved the pdf using two passwords. One password was for opening it and the second one for editng it. It was saved with any editing turned off. When I opened it in Preview on Mavericks the Preview app correctly displayed a password textfield to open it. After I entered the password it opened correctly. When I attempted a basic edit of the pdf, a simple rotatation of the image, Preview displayed a little note indicating that the original document was password protected so it made a copy of the original pdf. I was then free to edit the copy in Preview such as rotate, add txt, and so forth. I don't think this is going to make many people who distribute and sell password protected pdf files that happy. What the heck is going on here?

It looks like this issue may be limited to files that have been set to restrict the user's ability to print or edit the document (even after a password has been entered for viewing). I found that a password-protected PDF could be viewed in iBooks, but after I added the print restriction, I had the same problem you reported.

Password Protected PDF Files in Elementary OS

I have installed Acrobat 9.5.5 on my Elementary OS (Ubuntu base) system but when I try to open a password protected PDF file from my bank Acrobat fails with the error "There was an error opening this document. An updated version of Acrobat is needed in order to open this document.".
The version that I have installed claims to be 9.5.5 04/26/2013.
Has anyone got any pointers?
Thanks

Well, first, you probably don't have Acrobat 9.5.5 installed on Ubuntu unless you are running a VM image or using WINE to do so. You are probably using Adobe Reader 9.x. If a file was encrypted for Acrobat X and later then you do actually need Adobe Reader version 10.x or later. Unfortunately there isn't a version 10.x for UNIX/LINUX. What to do? Use a VM or WINE and load it up that way. If you really are running Acrobat 9.5.5 on Ubuntu via a VM image or WINE then you need to load Adobe Reader 10.x or Adobe Reader 11.x.
