Password protect a file beyond disk image?

Hi,
I've made a password protected disk image file, but once it's opened the file can be opened without a password every time.
Is there a way to password-protect a file, so that every time you try to open it, it requires a password? (like the way you can encrypt a PDF...)
Thanks!

From your earlier posts I gather that you would like to have a high level of security for your data. If an encrypted folder does not do the job for you, you may want to consider FileVault. However, if you use FileVault there are to very important measures you must take: 1) You must remember your password. If you lose or forget your password you will lose aceess to your data permanently. There is no way around it. 2) You must leave adequate space to be able to disable FileVault, should you every need to do so. The encrypted sparseimage requires almost double the size of the image to be able to be expanded.

Trying to password protect a file. Encrypted image created...now what?

I read this article:
http://support.apple.com/kb/HT1578
and I have created an encrypted image (.dmg) with no issue.
I'm trying to password protect a file on my computer. It is a Word document. I can't figure out how to move it to the encrypted image.
The support article said, "You can move files to or from an encrypted disk image as easily as you can from a non-encrypted disk image."
I tried dragging the file to the image....nothing.
Not sure where to go from here. Thanks in advance for the help.

The advice you're getting from mende1 is not accurate. If you accurately followed the directions at that link you gave, the disk image is certainly not read-only! When creating a new disk image, the default is to create a read/write image, so unless you changed that setting when creating the disk image, that's not your problem.
My suspicion is that you're not using the image file properly. Once you have the disk image file, here's what you need to do to put the Word file in question on it:
1) Double-click the disk image file that you created. This will "mount" the disk image as a "disk," which will show up on your desktop (if you have the Finder set to show such things on the desktop) or in the sidebar of any Finder window.
2) Drag the Word file onto the "disk" - NOT the disk image file! It should copy the Word file onto the "disk".
3) "Eject" the "disk" by dragging it (NOT the disk image file!) to the trash, or clicking the eject icon next to it in the sidebar of a Finder window. Once the disk is ejected, the file is locked and the contents cannot be accessed without the password.
4) For the most security, put the original Word file in the trash and choose Secure Empty Trash from the Finder menu. Before doing this, though, it would be wise to try to re-open the disk image and make sure you successfully copied the Word file onto it, and that you can open it just fine.

Password Protect folders (non sparse disk image)

So there are a collection of files I have protected on my computer using the disk utility method that everyone asking this question uses. I am curious to know if there is any other way of doing it. I want to password protect a folder within this protected disk image just becuase i feel like being extra sneaky and careful at the moment. I mean I could just use another sparse disk image inside the original and use two different passwords but I'm trying to be creative and that could get confusing. Does anyone know of a way to password protect a folder or file without using the disk utility method in Lion? Even if it requires third party stuff

Password Protected Folders (without using Disk Image)?

Hi All!
This is my first post on here and I'm in need of your help.
Basically, I need to add a password on to some folders but without using a disk image... So you literally click on the folder and it asks for a password in order to open - similar to when you add a password to a word doc.
Does anyone know how to do this, or if there is some kind of third party software which allows you to do this?
P.S. I'm currently running on Lion, however I do have a mac running on Mavericks too.
Thanks.
Matt

No. Not an OS X feature. What's your issue with using disk images? You can make them about any size you need, so they don't waste space.

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 protecting a file?

Can anyone tell me if there is a way of password protecting a file on my machine. I need it to be only opened by me even if someone else is using my user account.
I would really appreciate some help with this
Thanks!

You can zip it with a password (encrypt it). Unfortunately that option, even though it comes as
standard equipment, is available only from the command line (terminal.app).
http://opensoul.org/2007/4/9/creating-encrypted-zip-archives-with-os-x
You may create an encrypted sparse image on your desktop and store your files
in it. It's portable too,
just copy the encrypted image to a flash drive and take it with you.

There is "Meo" (a free file encryption utility):

There is openssl (comes with OS X), a command line tool (terminal):

There are tons more of them out there, but I recommend these, because the price is right

I can no longer access a password protected Numbers file with the correct password. Error message only says the file "cannot be opened."

I'm using Numbers version 3.2.2.
Suddenly I cannot access my password protected Numbers file with the correct password. I have the correct password written down so I know I haven't made a mistake.
The response box that pops up says that the file cannot be opened. There are no other options for me to choose from.

Also, I tried to open it through an older version of Numbers but it sent this error message.

HT3345 How do I open a password protected excel file created on a PC? I get a message that the "file is encrypted and can't be opened"

How do I open a password protected excel file created on a PC in numbers 09, on a MacBook Air? I get a message that the "file is encrypted and can't be opened"

This is actually not true; I support users who are doing this w/ Excel 2011 (v14.2.2+) for Mac and Windows users w/ Excel 2003 & 2007. Win users are from finance dept, and who have pasword-protected various budget files. The Mac users are (surprise) "creative" users, who enter pw to unlock and edit these budget files.
These files are shared from a Mac server (running 10.6.8 server), and I do have an erratic problem where all users have read-only access to these pw-protected Excel files. The manual work-around has been to copy the troublesome file(s) and confirm users have full access again. I also do a shuffling of filenames, so that the new, working file has original file name.
FYI: the Mac server POSIX and ACL permissions are correct, and don't appear to be source of the problem.
It's easy an SMB file-locking issue or concurrent users trying to edit these files. I keep reminding them that Excel is not a database!

Hey guys, how can i password protect my files in external hard drive? I want to access those files both from mac and windows PC!

If you want a cross-platform solution that doesn't require the use of third-party software, use an external drive with hardware encryption. The device will have either a physical key or a numeric keypad. I don't have a specific recommendation.

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.

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

hi,
To populate data in different column you may use the below code.
DATA : filename TYPE string VALUE "Path
DATA :BEGIN OF wa_string,
               data TYPE string,
          END OF wa_string.
DATA : it_data LIKE STANDARD TABLE OF wa_string,
           data TYPE string.
DATA: v_tab TYPE char1.
v_tab = cl_abap_char_utilities=>horizontal_tab.
CONCATENATE 'happy' 'new year' INTO wa_string-data SEPARATED BY v_tab.
APPEND wa_string TO it_data .
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
    filename              = filename
TABLES
    data_tab              = it_data.

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.
