Cannot open password protected .pdf files?

I have an ebook for school that requires a username/password combo to open. It of course opens on my computer, but when I try to open it on my Galaxy III, it says there was an error opening the document. It also will not open with my Galaxy Tab 7.0. I have the most updated versions on both devices.
Can I not open this type of file with Adobe Reader?
Please help!! I need to be able to open this ebook on the go!
Thanks so much!!!!!!!!!!!!!!!!!!!!!!!

Thanks Michael for your speedy reply. I have been reading on the Adobe site and I figured that much. I buy knitting patterns and crochet patterns at a cost and I download and print them. I 'save them to My Documents', some of the older ones I can bring up and print again but it has been just recently that the new ones will not allow me to view them. I know you can get password breaker software. Do you think it is a good practise to have such software in your computer? Thanks again. JenonDenman.

Can't open password protected PDF files.

As per the thread title, I can't seem to open password protected PDF files via the Mail app.
I've read that you can open them if they're synced and opened via iBook, however, this is not an option for me.
I get sent several password protected PDF for work per week and would like to be able to read them directly from the Mail app just like a regular PDF file.
Does Apple know of this issue and will they implement a fix in the near future?

Will the new iPad open password protected PDF files?

I attend college online, and have always had a problem viewing password protected PDF files on my iPad. Will the new iPad allow opening these files?
Thank you!

You can install the same iOS version running the new iPad onto your iPad.
Download the free Adobe Reader app from the App Store. It opens password protected PDFs just like thee desktop version.

Now i am able to create PDF with Digital signature. But We want to assign password protection too..and problem is once we fix Digital signature we can't change security.
My problem is to pass password at the time of opening PDF for embedding signature. Password window should not prompt to the user while running VBA application.
Can you please help me to pass password on fly when file prompt password while opening PDF file. As file need to be opened at the time of fixing signature using sdk javascript code.

Correct, you need to encrypt then sign.
Unfortunately, there is no way to pass a password for opening.

Unable to open password protected PDF in safari

Dear all, I'm new in using iPhone safari. I have problem in opening password protected PDF file from safari. Do you have any solution or workaround to resolve this problem
Regards
BR

You can put pretty much any character into the encryption password for a PDF file apart from control codes (carriage returns, backspaces, etc), but whether the vendor's website can is another matter!
As you seem to have a PDF with a user password that isn't what you expected, there's nothing you can do to remove it other than perhaps trying a version without the quote characters, or with a backslash in front of the quote (it's possible they escaped the string on the login form in preparation for storing it in a database, and forgot to unescape it again).

REQUEST: Support for password-protected PDF files and SD-card installation

I would like to request for the features in the topic.
The current version can't open password-protected files hence I still need to download them on a PC before viewing them.
SD-card install is necessary for some devices running on Froyo as they don't have a lot of internal memory.
Thanks in advance.

Hi AndrewSV,
I am sorry to hear that you are having problems opening password-protected PDF files, and that the users are being prompted for a password, which shouldn't be required for Viewing and Printing the file.
I have opened up a [https://bugzilla.mozilla.org/show_bug.cgi?id=900822 bug for this issue], and our engineers and volunteers will be able to investigate this issue.
Yes, please attach the write-protected PDF as an example, so that they can see what's happening.
Thank you for your help! =)

Password protected pdf files in c7

i am not able to open the password protected pdf files in my c7..it does not even show an option for typing the password..it just show the file is password protected and cannot be opened..i never found such problem in my old n82..why nokia is doing like this in new upgraded phones ...any solutions for this...please...all my mobile bills and credit card bills comes via password protected pdf files...

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.

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

Acrobat 8.1 and C# - How can you detect password protected PDF files?

I am modifying our existing C# code that opens PDF files. But when ever we hit a password protected file, we are prompted for a password. This is an automated process, so if we detect a password protected file, we move the file to a manual processing folder to be processed later.
We are using Acrobat 8.1 Standard.
Our code looks like this:
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Text;
using
Acrobat;
using
System.IO;
using
Word = Microsoft.Office.Interop.Word;
using
System.Reflection;
     AcroApp app = new AcroApp();     app.Hide();
     try
          if (app != null)          {
               app.CloseAllDocs();
               AcroAVDoc av = new AcroAVDoc();
               if (av.Open(filename, "Test") == true)               {
                    AcroPDDoc doc = new AcroPDDoc();                    doc = (
AcroPDDoc)av.GetPDDoc();
                    doc.Save((
short)Acrobat.PDSaveFlags.PDSaveFull,
                    Utilities.GeneratePath(FileVersion.TEMP) + fi.Name.RemoveFileExtension() + ".PDF");                    doc.Close();
     catch (Exception ex)     {
          ErrorLog.LogError(filename.RemoveFileExtension(), ex);     }
     finally
          app.CloseAllDocs();
          app.Exit();
This works great for non-password protected PDF files, but it prompts for a password if the file is password protected. I was looking at the FileOpenEX functionality, but I can not find the reference to bring into my C# project. It looks like it is only for C++, since I could only find C++ examples.
Any help would be appreciated.
Thanks,
Tom

There are no methods in the Acrobat SDK for C# for what you wish to accomplish.

OBIEE 11g having problems with password protected PDF files.

I have been able to get an analysis in OBIEE 11g to display PDF files.
However, some of these documents contain sensitive information and must be secured. Since anyone with access to the file name
could simply type in the proper path in the browser window, this is unacceptable. In order to try and prevent this, I created a pdf file
that is protected with a password.
Opening the file by itself, produces the desired results. The password is requested before the file will open.
When I open the file through my analysis in OBIEE, Adobe reader activates, but the password is not requested and the file does not open.
It is as if OBIEE is somehow not sensing that Adobee is asking for a password.
Does anyone have any experience with this?

FYI, in case anyone is interested, I found out what is going on.
I created the original password protected PDF using Microsoft Word. I did this because I do not have a full version of Adobe Acrobat that allows me to create files.
On a hunch, I found someone that has a full version of Acrobat, and had them create a password protected PDF file. This file worked perfectly.
Apparently, Word is not strictly adhering to PDF guidelines, and OBIEE senses the differences, resulting in the file not opening properly.
Something to keep in mind for anyone linking to password protected PDF files in OBIEE.

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...
