Encrypted or Password Protected Text Files?

I don't suspect there's anyway to protect text files that I load on to my iPod, is there? That would be a very cool feature to add in the future, even if it's using the "safe combination" technique used to screen lock.

that I load on to my iPod, is there?
I've sucessfully done this already. The files remain perfectly readable but you won't ever understand them again (but that's a small price to pay for the peace of mind you get).
Looks like the screenlock's your only answer!

Please help me for the following:
How to encyypt and decrypt the text file using standard encryption alogrithms like DES, MD5, RSA? Are there any standand function modules for both encryption and decryption which accepts a user defined public key?
How to download a password protected text file?

How create encrypted/password-protected zip file?

Any idea if there's a way with the Java API to create an encrypted and password-protected ZIP file? I know how to create a zip file with Java, but I need encryption and password protection.

Thanks for the link, but that's not a solution. It's 3 years old (and still not resolved) and I'm looking for a Java solution.

Hi
You could use OLE to integrate SAP with Excel - create files, execute macros etc. (search for DOI on SAP help), but this will only work on the presentation server, so you couldn't run it as a service in background. I suppose your e-mails are sent through the internet, hence the requirement for encryption -- or maybe your client doesn't trust its network people! For this you really should use strong encryption -- anything less, you might as well send plain text. One solution to this would be to send the email down a VPDN -- this would encrypt all traffic between source and destination. Another would be to encrypt the file just before it is attached to the email. This could be done within ABAP, but perhaps a third party public key encryptor would be better placed. This could be invoked via a system command call, or as an RFC. A third solution would be to have your mail server handle the encryption.
Heres the link for the above explaination

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!

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.
Chrystal

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.

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!

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.

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.

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.

Convert Excel into Password Protected PDF Files

Hello Aandi/Lenoard,
I believe you are the Adobe Forums administrators so I thought you guys are the right people to approach.
OTHERS ARE ALSO INVITED TO COMMENT ON THIS TOPIC.
I have C# desktop app which generates Excel files and our goal is to convert these excel files one at a time into password protected PDF files. We use a 3rd party software currently, but I am challenging myself into saying that I can use Adobe Acrobat 9.0 SDK to achieve what is required .
I have downloaded Acrobat 9.0 SDK and also have Adobe Professional 8.0(trail) in my development machine. Can you firstly tell me if this is possible and secondly what would be required on the client machines to run it?
THanks,
Andy

"Encrypt with Password" is the policy name, not the policy id.
Did you try enumerating the policy object to see how to set it up? I ran this from the console to get the policy details:
var policy = security.chooseSecurityPolicy();
for ( var i in policy )
console.println(i + ": " + eval("policy." + i));
That will pop up your list of policies. Choose "Encrypt with Password" and hit Apply, which returned the following:
policyId: SP_STD_default
name: Encrypt with Password
description: This policy will allow you to set an open or modify password on a document.
handler: Adobe.Standard
target: document
Of course, all you really need are the policyId, handler and target. Make sure you read and thoroughly understand the security requirements documented in the API reference for this method as well.

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.
http://support.apple.com/kb/HT1578
There is "Meo" (a free file encryption utility):
http://www.nchsoftware.com/encrypt/index.html
There is openssl (comes with OS X), a command line tool (terminal):
http://osxdaily.com/2007/05/02/quickly-encrypt-a-file-with-openssl/
True Crypt (one of the most powerful solutions out there - and its free):
http://www.truecrypt.org/
Cryptor (a simple easy solution):

There are tons more of them out there, but I recommend these, because the price is right
and they will get the job done.

Protecting text files with sensitive information

I have an app where users log in and upload files with very
sensitive information (pdf's or word doc's). Depending on the
permissions an user can open and view or save specific files. I'm
saving files out of the web server folder and using middle cfm
page(docs.cfm) as a wrapper:
Link to the docs.cfm:
<a href="##"
onClick="MM_openBrWindow('docs.cfm?name=#docFile#','fileDoc','scrollbars=yes,resizable=ye s,width=750,height=550')">#docName#</a>
and here is docs.cfm code:
<cfheader name="Content-Disposition" value="attachment;
filename=#URL.name#">
<cfcontent type="application/unknown"
file="#Application.docsPath##URL.name#" reset="yes">
Application.docsPath variable points to D:\myFiles\ folder
(not in the web server directory).
It is sill possible to open file if you guess the file name.
Is it any way to protect files from unauthorized users and to
block them if they try to guess and open a file?
Thanks,
b.

I think the best way to protect them would be to store them
in a database and
restrict access to the database. The database should also be
outside the DMZ.
SQL 2005 has some field level encryption if you want to get
supper protective,
but that has some limits of data length that you'll need to
work around. We
encrypyt user passwords with SQL 2005 and it works great.
More info here:
http://blogs.msdn.com/yukondoit/archive/2005/11/24/496521.aspx
The other possible solution is to place all a user's files
into 1 zip file and
encrypt and password protect it, not as secure, but would
work. You could use
their userid and email or something for unique username's and
passwords per
file. Each user would have their own zip that you unzippped
to give them access
to what was inside. When they uploaded the file, you just add
it to the zip.
This way you could allow them to upload differant types of
files and handle
them all the same way.

Cannot password protect CSV file

I had a CSV file (workbook) that I password protected. Up until yesterday, I was prompted for a password to open this file, but this morning, I was not longer being prompted for a password. I tried opening the file in Excel 2013 and 2010 with the same result.
I tried to create a new CSV file (in both versions) and password protect the file (similarly to what I had done before) but the file did not retain the password protection.
Has anyone had problems password protecting a CSV file? Is there somewhere documented that .CSV files do not support password protection.
I am a little puzzled why it was working for several months, but now it is not.
Thanks
Andres

Hi,
I agree with Mr. Hans, we cannot password-protect it from Excel. I suppose that your CSV file may be encrypted with some code/third-party program. Please see the sample below:

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!

nails:
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.
Here are a few articles that might be of interest to you:
