Unlocking password protected PDF

I have Adobe Reader on my Android tablet and am unable to unlock a protected PDF document. It allows me to enter my user name and password as well as selecting the checkbox for "Remember my user name and password"
The issue I have is that it does NOT allow me to unlock the document.
The document is an eBook Collection textbook.
Please advise how to resolve this issue.
If Adobe Reader is unable to do this, is there another app for Android that would allow this?
I have no issues unlocking the same document on using Adobe Reader on my desktop (Windows 8).
Thank you

Hi Bernd
I simply unlocked the password protected pdf (which had been created in acrobat 6) by using the drop down menu from "Secure" and choosing "Remove Security", I was then asked was I sure I wanted to remove security, answered yes and bingo it had no security!
My repro department were astounded I could do this with a trial program. My MD is alarmed and if some of our customers were aware they would be having kittens. (We do a lot of legal documents which have to be locked).
If you send me a password protected pdf I will see if I can return it unlocked (this works with V6 created pdf's and guess it would work with others?)

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.....

Unlock password protected, reader extended document

Hi,
I'm trying to unlock/remove password on a password protected and reader extended document in a long lived process. Below is the workflow description
A batch process that fires periodically to send service feedback forms to customers.
Long lived process to Gather data ---> Render Dynamic pdf ---> Password Protect (to disable printing and extracting pages) ---> Reader Extend (for saving edited pdf on client machine) ---> Send Email to customer.
Long lived process to Receive feedback via Email endpoint --> Remove/Unlock (?) password ---> Extract data from PDF ---> further operations to update data in tables.
My findings:
Remove PDF Password Encryption (Failed here) ---> Extract data
Error: ALC-ENC-100-005 You cannot change security on this document because the document is signed or certified or reader extended.: ALC-ENC-100-005 You cannot change security on this document because the document is signed or certified or reader extended.
Remove Usage Rights ---> Remove PDF Password Encryption ---> Extract data == SUCCESS
Unlock Password Encrypted PDF ----> Extract Data (Failed here)
Error: com.adobe.internal.pdftoolkit.core.exceptions.PDFSecurityAuthorizationException: Security Manager for decryption is not set: com.adobe.livecycle.formdataintegration.client.ExportFormDataException: com.adobe.internal.pdftoolkit.core.exceptions.PDFSecurityAuthorizationException: Security Manager for decryption is not set

I see that the "Unlock Passwod Encrypted PDF" service works fine in Short Lived Process. I'm unable to make it work in Long Lived process. Can someone please explain this behavior? Why is the limitation to Unlock PDF Password service to work only in short lived process?
Thanks,
Sandeep

Sandeep,
Is your intention to remove the password encryption or just extract data from it?
If you want to remove password encryption then you should first remove the usage rights and then remove pass encryption
If you want to just extract data from it - You can create a short lived subprocess that has unlock PDF password and extract data which should work fine (Ensure that unlock and extract are in a short lived process)
In case of long lived process when you unlock PDF password - the PDf gets unlocked and will be saved - and if you try to extract data it would fail because you need to unlock it again.

How to read a password protected pdf on a surface pro 2?

Has anyone been able to successfully open a password protected PDF on a Surface Pro 2? The Adobe Reader app doesn't work on the surface pro 2 with protected PDFs.

Use Adobe Reader XI, the regular Adobe Reader for any Windows system.

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.

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.

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.

Reader plug-in, save copy of password protected pdf without password

Hello,
We currently have an Acrobat Reader plugin (using the 8.1 SDK) and are having trouble with password protected PDFs.
The sole purpose of our plug-in is to pass a copy of the currently open PDF to a different folder on the user's computer. The problem we are facing is with the password protected PDFs. We would like to pass a copy of the PDF that doesn't have the readonly password protection.
Scenario:
1. The user opens a password protected PDF in Adobe Reader.
2. They are prompted for the password, they enter it and can see the PDF. 3. Now they click our custom button.
4. Save a copy of the currently open PDF without password protection
Since we already know they have entered the correct password, in theory we should be able to either save all of the content to a new file, or simply remove the password protection.
Can anyone point me in the right direction so that I will be able to get a PDF without the password?
Thanks,
Ryan

Hi again,
I was doing some research in the API reference and examples and I think that for my business problem, it will be sufficient if I can get the read access password. I found that I am able to use the following:
AVCryptGetPassword(pdDoc, permsWanted, (void **)&password)
This prompts the user to enter the password and puts the actual password in the &password variable, which will will work for us. Ideally though, I would like to not have to prompt the user again for the password since they already entered when opening the pdf, is it possible to get access to the plain text of the password that they typed when opening the pdf or another way?
I tried:
StdSecurityDataRec* secData;
secData = (StdSecurityDataRec*)PDDocGetNewSecurityData (pdDoc);
if (secData) {
if (secData->hasUserPW)
char* mypw = secData->userPW;
However, the password is encrypted. Thanks for your help!
Thanks,
Ryan

How to split a password-protected PDF file?

There is a tutorial to let you know how to split a password-protected pdf file, check in here:http://www.kvisoft.com/tutorials/split-a-password-protected-PDF-file.html

Yup. You all are right. I ordered Adobe Acrobat today and the order is still processing. I can get to Adobe Acrobat.com but that too does not work. I guess I will have to wait until my order is processed before I get the keys to the kingdom. Thanks for your help and please forgive my ignorance.Regards,Bob

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.

Cannot open a password protected PDF file on my ipad

WHy can't I open a password protected PDF file on my ipad even after I enter my password.

Someone on another forum said you can with the app Goodreader Lite, but I haven't gotten to try it yet. I will let you know in about 45 minutes.
