Image File Encryption

Just like most on the forums around the net, having serious issues with BB encrytption of jpg's. BB stopped working and transfered all 400 pictures off of it (thankfully) to my Mac. I could not view the .jpg.rem images on my Mac, however I figured I would let it lie based on most of the posts. Got back my BB and transfered the images back onto the BB and all I see are image files with hourglasses? Tried turning off and on encryption, tried renaming and transfering files, emailing them, switching folders and just about every possible combination...to the point where I see that the "damaged or corrupted" error.
I still have the original transfer of files to my Mac, is there anyway I am ever going to see these pics again?

Nope, sorry. The encryption must be removed while on the SAME device, with the SAME operating system which contains the encryption keys. Once the device was wiped and the OS reloaded, those files are worthless.

Is it safe to back up a disk image file when it's mounted?

Hi -
I use some small, encrypted ".sparsebundle" disk image files to keep my diary, banking info, etc., on. When I'm at the computer, I keep them mounted all the time.
Is it safe to let Time Machine automatically back up the .sparsebundle disk image files, even while they are mounted? Or would there be a possibility the backups would be corrupted, if the operating system hadn't written out cached data or something to the disk image file?
In other words, if I save any open documents on the mounted disk image, does the disk image file on disk always contain the fully-saved document and a consistent file system? Or could there still be some data cached in RAM, that would not be saved at the time the .sparsebundle file was copied? Is it always necessary to unmount a disk image before duplicating its .sparsebundle file?
Do I need to turn off Time Machine's automatic backup, and just do manual "backup now" after unmounting the disk images? That's a major pain in the behind... I really want to just let Time Machine do it's hourly backups as usual, but of course there's no point if the backups are corrupt.
Of course my own guess is "to be safe", I should unmount them before backing up. But again it's a big pain if it's not actually necessary. Does anyone know for sure?
Thanks...

My understanding is that Unix, generally, doesn't write everything out to disk immediately. There is caching in RAM to speed up disk access, including modified superblocks, modified inodes, and delayed reads and writes. Now, if you ask to read an individual file, the kernel makes sure all the cached data is written before it returns the read data. But if you try to do, for example, a block copy of the whole filesystem, the kernel doesn't know that, and there's no guarantee or expectation that the filesystem will be in a coherent state.
That's the purpose, for example, of the "sync" command - to write all this cached data to disk before unmounting, shutting down, etc., and, that's why the OS gets so upset if you just unplug a firewire drive. Because even if you've saved and closed any open documents, they haven't necessarily been fully written out to disk yet.
So what I don't understand, is how people are ever able to back up mounted disk image files without them getting corrupted. I mean, you'd think they would get corrupted all the time. It would be the equivalent of just unplugging your firewire drive before you made a backup of it, or of doing a block copy of a read/write mounted filesystem. There ought to be a very good chance of the filesystem being scrambled. So, why does it not happen?
Is there something different about the Apple filesystem, or Apple disk images? Or, maybe we're only talking about delay times in the cache of fractions of a second, so as long as you haven't written anything within a few seconds of the copy, and don't write anything during it, you're ok?
Even if Apple reps won't answer my question, the kernel and most likely all the low-level disk i/o and filesystem stuff is open source. Surely there's someone out there who would be knowledgeable enough to give a definitive answer? I was hoping to find someone like that here... I do appreciate your taking the time to answer my post, but maybe I need to go elsewhere, on some developers' mailing lists or something? Does anyone know of such a place I could start looking?
Thanks...

File Encryption

Hi Guys!
Need some help and advice please! Basically what I'm trying to do is this. I have created my own encryption package which reads in strings and encrypts them using a secret key and then decrypts the cipher when provided with the secret key. What I need to do is encrypt files using this package. So for files with the extension ".txt" this should not be a problem as I could read in the text using a Reader of some sort and encrypt the contents to a new file, then delete the original file. However is there any way I can encrypt files of other types? Such as for example word document files and to an even greater degree other types of files such as music or image files?
Thanks :)

well, buffered reader would not be best choice for biary files or any other not plain text files.
you should look into API (that friendly link, in the left column of this page, that says 'API'), and look into java.io or java.nio packages.
if you want to read file, then maybe FileReader (just a quess) would help you....
however, if you're encrypting some kind of file that has known format, like .doc might have, then you should know, that it makes it easyer to break your encryption, because attacker allready knows how this file should beginn (probably it has some .doc specific header).
to overcome that problem, you should add salt to the text you're going to encrypt... that means you should mangle that text before crypting, so that id would not look like the original text did...

[Tip] How to protect Image file

Hello,
If you have ever wanted to protect your image file,
especially within your Flash content,
this article will be helpful.
First of all, there are some points you need to protect when
you deliver image data with Flash.
1. Internet Browser Cache.
Even though you use 'HTTPS' protocol when you deliver your
file,
if it is pass the 'Network (or Protocol) Layer' of your
machine, it is already in 'plain' data
(not encrypted), and can be read by Internet Browser.
Those 'plain' data will be stored in Internet Browser's
Cache directory.
There are many Internet Browser Cache reader programs, and
they can intercept those
data before the Internet Browser program deletes the cache
files.
So, just using 'HTTPS' is not an answer. You need to encode
your image data
with your own (or with well known cypher algorithms)
encoding/decoding methods.
In this article, I want to explain more detail about this. I
scramble the image
so that make it hard to figure out what the original image
was, not only with human eyes
but also with 'strong enough' 'Key' length.
2. Screen Capture.
Even if you encoded your image data, it will be finally
shown on your screen,
without any noises, or any other ugly filters.
So, you can 'Capture' your monitor screen itself.
There can be many ways to avoid this. First, you can erase
the system's 'Clip board'.
You just can erase it regularly, or you can detect whether
the Internet Browser -which is
showing your image data- is active or not and erase clip
board when it is active (in foreground),
and hide your Flash area when the browser is inactive (in
background).
If a hacker just take a picture of monitor screen with high
quality Camera,
you still can avoid that, by showing some black rectangle,
or any layers on the screen
regularly only in very short period (like mili-second). But
I think this way sometimes you feel
tired or be annoyed when you watch that kind of blinking
screen.
== About my code ==
What I want to present here today is 'modifying(encoding) the
image' data itself.
There are many ways you can try for modifying your image data
and revert it back to original data.
You can use legacy block cipher algorithms like DES, AES, for
encoding and decoding the
image data, because the image data (RGB values) what Flash
uses is actually a combination of 'bit's.
But if you decode the 'encoded image' data, you probably use
'get pixel'/'set pixel' function for
reconstructing the proper 'RGB' value of each pixel. But I am
sorry that this function is extremely slow
so that you need to wait for a couple of minutes to see an
image.
So, what I want to show you today is 'Scrambling the image'
like 'picture puzzle',
with using 'copyPixels' function which is 'extremely fast'.
(Actually, there can be many other solutions for this, so
please don't hesitate to proceed your own research)
Let's say you have 8*8 pixel size of image blocks, and you
completely disorder those blocks for
entire image area. That size of block is too small to figure
out where it should be, with our
humble human being's naked eyes. So, you need to know the
'answer', which is saying what image block
was originally on which 'cell'. This 'answer' is the 'key'
for my simple 'image scramble' logic.
The 'key' I said here, you should understand that, is the
'key' value of normal 'block cipher' algorithms.
So, if you know the key, you can rearrange all those 'blocks'
back, but if you don't know the key,
simply you can't do that, or you need to wates tremendous
time for that.
Here, I use 16*16 size block for your eye's convenience, and
with 8*8 size of 'matrix' which is
comprised of each 16*16 size blocks. I mean, one 8*8 matrix
has 64 blocks, so each block of
one 'matrix' can be at '1st cell of matrix or 64th cell of
matrix. So, the 'odds' is 'Factorial of 64',
which is 64! == 1.268869322e+89 .
Let's say you know my algorithm (complete source code), and
you try every different 'matrix' values.
If it takes 0.001 seconds to test one 'matrix' value you have
chosen, it will take
"(64!) / (1000*60*60*24*365) =
4.0235582250724303685766549129617e+78" Years!!!! to find exact
matrix value.
== FLA sample ==
In my sample *.fla file, I embedded all those 'key' values.
So, you can not use my sample directly for your
own project. But I think this sample will give you an useful
idea for your own implementation.
<* Exchanging the key values *>
For example, you need to get the 'key' values from the
server, only when it is needed.
You can use 'loadVariables()' function for this purpose.
But, all data delivered by 'loadVariables()' or
'getUrl()', or any other functions of Flash, are
'Cached'.... So, you need to exchange that 'key' values
more safer way.
One of that 'safer key exchange' is to use 'token'. For
example, when the client requests the key value
to the server, the client should generate an random value (I
will call it 'token') and send it to the server.
Now the server modifies the 'key' value 'with the token',
and sends back to client. Finally, the client
decode the 'key' value with the token value it generated.
As you can see, my logic is just 'rearranging each blocks'
with respond to the given matrix values (key).
It is really really simple. There in the ActionScript code,
you can see 3 matrix, and some other variables.
var chessunit = 16 // Size of block
var arrayw = 8 // Width of Matrix
var arrayh = 8 // Height of Matrix
var arraysize = arrayh * arrayw
var chessarray = Array (arraysize) // Matrix for decoding
chessarray = Array
(64,37,5,35,45,25,52,38,12,61,34,23,3,26,39,58,32,28,17,2,60,16,59,19,57,48,43,18,47,21,4 0,15,31,6,44,46,30,51,27,56,20,24,13,7,42,1,49,54,36,53,9,50,4,8,10,14,33,11,22,63,55,29,4 1,62)
// In case of the width of an image is not exactly the
multiple of the width of matrix,
// we need to encode the right most area of the image.
// So, I simply use another matrix for only that area.
// Maybe You can generate more bigger image, of which the
width of it is exactly the multiple of
// the width of matrix. And you let the decoder to show only
the original size of the image.
// Please try yourself. :)
var dwArray = Array
(32,19,3,18,23,13,26,6,31,17,12,2,20,29,16,14,9,1,30,8,10,24,22,11,15,28,7,4,21,25,27,5)
// In case of the Height of an image is not exactly the
multiple of the Height of matrix,
// we need to encode the bottom most area of the image.
// So, I simply use another matrix for only that area.
// Maybe You can generate more bigger image, of which the
Height of it is exactly the multiple of
// the Height of matrix. And you let the decoder to show
only the original size of the image.
// Please try yourself. :)
var dhArray = Array
(40,23,4,22,29,16,33,24,8,38,21,15,2,17,37,20,18,11,1,10,12,36,30,27,13,25,28,14,19,32,35 ,7,5,26,3,31,34,6,9,39)
You can change the block size, matrix size, any values you
want.
By the way, if the block size becomes smaller, you'll get
more stronger security level. But you have to
compensate it with the slow down of the performance.
** Ooops, I can not attach my sample *.fla file, but only
ActionScript code here...
But I believe you can try without testing my *.fla sample.
If you really want to test it, please mail me.
([email protected])
** You need to 'export' image object, with the name of
"img0".
== Image encoder ==
Encoding (Scramble) the original image is also simple. You
just need to copy each blocks in reverse of
the 'ActionScript code'. That's all. You just use same
'matrix', but copy source and target reverse of
ActionScript code. I think you can write it with any
languages you like, C/C++, C#, Java, and
anything.... right?
== Block cipher ==
Now, you know that my implementation is kind of 'intuitive'
representation of 'block cipher'.
More precisely, it is called 'ECB', which encodes each
encoding block (matrix) with the key values
from the beginning to the end. You can twist the matrix every
time you pass one matrix area of an image.
It is called 'chaining'. There are some 'chaining' block
cipher methods like 'CBC'...
(If you want to know more, please look up "
http://en.wikipedia.org/wiki/Block_cipher_modes_of_operation
Thank you for your time to read my humble article,
and wish you Good luck. :)

Hello Crandom,
If you want to encrypt a critical strings, like special
server script url or parameters, then it is simple.
The most simple and faster method is to "XOR ing the string"
with a key string. You use the same key string when you encode and
decode (by Just using XOR). This is similar to 'Stream cipher'
algorithms.
And there is "open source cipher algorithm" (called
AS-CryptoLib) written in ActionScript, including most of algorithms
like Hash, Block cipher, RSA... if you want more stronger
encryption strength..
But I bet you also want to encode your script logic itself.
In that case, you should write your own 'Interpreter'. For example,
you encode all your ActionScript source code string, and decode it,
and you interpret each script tokens like 'if' 'for' 'while',
etc...
Actually, your question also inspired me to think about
loading script string and run it on the fly.
Maybe.... we can start from this article...
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_16691"
I suggest you just use commercial SWF file encrypting tools
like Ameyata's "SWF encrypt". It changes the SWF file structure so
that usual 'SWF file decompilers' can not read codes properly.
And.... If you can use Flex2 (for your current project), and
it is ok with you (If you don't need to change a lot in your
current project) to use JavaScript to control your objects or
behavior of SWF file, then I think there is another possible way.
After you decode the Javascript string, you load a web page,
or change the content of HTML file already opened, so that your new
script will be working, as what you wanted to be. But I didn't test
it :)
Best regards.

Sending an Image file via UART

Hi All,
1. Is it possible to send an image file( .jpg -1080p) from PC to FPGA(ML605 evaluation board) via UART ?
2. .jpg to .hex to .txt then through hyper terminal ? or any other way ?
Meganadhan

thanks ignacio
i will try it letter
but for sending an image to fpga, can i use realterm? actually i'm doing image encryption project and the size pixel is 1600X1600, it's very big , but it's ok if it will take a long time for transfer it via UART because i just want to make sure that my alghorithm was true.
and i have some trouble with the uart rx code. i would like to simulate it with random bit that represent transfer bit from pc, but it's hard to sychronise the timing between uart rx and the random bit program , here the code

Time Machine (OSX) doesn't back up files in Mount Point or Disk Image File

Hi all,
I have two disk images which are scripted to be mounted on login. These two disk images are always mounted to the same location. These two disk images are encrypted TrueCrypt volumes.
Time Machine (TM) will only back up the disk images the first time they are mounted, but not after that. As I modify documents within the volumes throughout the day, the modified timestamps are adjusted properly. However, TM does not back them up. TM never backs up the mount points which are two folders within my home directory.
Any ideas as to why neither the mount point or the image files are backed up? Do the image files have to be closed (unmounted) after being modified for TM to back them up?
Now if TM won't back up the image files because they are locked/open, then why does it back them up the first time even though they are mounted? Also, from what I've read, TM should back up any HFS+ drive which is mounted. Both these drives are HFS+, so it should back up the mount points? I can verify this by doing a 'mount' in the terminal, the following is echo'd back:
/dev/disk0s2 on / (hfs, local, journaled) (Main System Drive)
/dev/disk1 on /Users/username/Folder1 (hfs, local, nodev, nosuid, journaled, noowners, mounted by username) (First TrueCrypt volume)
/dev/disk2 on /Users/username/Folder2 (hfs, local, nodev, nosuid, journaled, noowners, mounted by username)(Second TrueCrypt volume)
Any ideas will help!
Thanks,
Chris

Here is the resolution:
Apparently time machine checks the parent folder's timestamp before moving into that folder to look for modified files.
So as I was modifying files, the timestamps on the volumes were changing but not the containing directory. Because of this, TimeMachine saw the parent directory had not changed, so did not look for the changed volumes inside.
So to resolve this, I wrote a simple touch script which touches the parent directory to match the modified volumes timestamp (if there is a modified volume).
Thanks,
Chris

Opening disk image files in Windows?

Is there anything, free software or something like MacDrive (which I've never used) that will open disk image files, particularly encypted ones? I keep an encrypted disk image on my thumb drive with important information and I'd like to be able to open it in Windows. I recently came across the open-source TrueCrypt for Linux and Windows, but I would love some kind of software that would work on all three platforms, or at least OS X and Windows.
Thanks,
Alan

PGP works on the Mac. They currently do not have a working version for intel based Macs. Your profile indicates you have a PowerMac so you should be good to go. Download the free trial and check it out.

Dividing a dmg Image file

Im hoping one of you guys has an answer....
I've created about 4 disk image files on a mac at work that I wanted to transfer to my ipod. After learning that i cannot transfer a file over 4gigs or so to the ipod because its based on a "fat32 system" I therefore need to split the 4 dmg files that are about 7 gigs each in half. When I try to transfer these to the ipod, the transfer goes up to the very last few megabytes and tells me that it cannot continue because there is information missing from the file. Is there any way in disk utility or another app where i can split a dmg file in half or something of the sort? Thanks!

You can use Disk Copy 6.4 to open a .dmg file which isn't compressed or encrypted in Mac OS 9. The link is a direct download.

Error "A web exception has occurred during file upload" when trying to import ESXi image file into Update Manager

I'm encountering this error and not sure how to fix, I'm quite new to vCenter so please bear with me.
I'm trying out vCenter 5.1 with Update Manager 5.1 right now. No license key has been entered and I still have 50 odd days to try it out.
2 ESXi hosts are being managed by this vCenter, and they're both running ESXi 4.0
I'm looking to use Update Manager to try to upgrade the ESXi 4.0 hosts to ESXi 5.1
I downloaded the image file VMware-VIMSetup-all-5.1.0-799735.iso from VMWare website, and is looking to import it using the Update Manager so I can update the ESXi hosts, but I keep on getting the error:
File name: VMware-VIMSetup-all-5.1.0-799735.iso
Failed to transfer data
Error was: A web exception has occurred during file upload
I tried importing it by using vSphere client to connect to vCenter server both remotely and locally, with firewall disabled.
I've read http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1026602
I've disabled firewall, and there is no anti-virus program on the server. I've also restarted the machine several times, to no avail, I didn't reinstall update manager because the whole Windows and VCenter installations are clean from scratch.
I logged into the vSphere Client using Active Directory credentials, and I've made all Domain Admins (which my account is a member of) part of the administrator group on the vCenter server. I can't log in using admin@System-Domain because it tells me I don't have permissions for it, I still haven't really had the chance to figure out why that is and not sure if that makes a difference.
Also, I'm fairly certain I'm using the right image file, as I've burned some DVD's used that image file to upgrade some other ESXi hosts. Unless there's a special image file I need to download?
I'm at lost on what I can do to make it work. Please advise.
Thanks.

The ISO file you mentioned is the one for vCenter Server. What you need is the "VMware-VMvisor-Installer-5.1.0-799733.x86_64.iso" (or VMware-VMvisor-Installer-201210001-838463.x86_64.iso) for the ESXi host.

A generic error occurred in GDI+ while assing tiff image file to Bitmap and Image

Hi,
I am getting "A generic error occurred in GDI+" error while reading the tiff image file to Bitmap or Image.
Below is my sample code.
string filePath=@"c:\Images\sample.tif";
Bitmap bmp=new Bitmap(filePath); // here getting exception
int totalpages=bmp.GetFrameCount(.....);
etc......
I tried using Bitmap.FromFile() and also from FromStream() even for Image also but there is no use.
Moreover i m having full permissions for the file path and the tiff file is having multiple pages.
Can anyone help me to solve this issue please.
Thanks & Regards,
Kishore

Make sure that the Tif file is valid (can other software open it)? If you are able to save a Tif using GDI+, try saving that Tif, then opening it. Part of me wonders if there is something about that specific Tif that GDI+ doesn't like.
You could also try using WIC to open the TIF, perhaps you would have better luck there.

Error: Unable to locate an image file browser...

I get the error below when I insert an image element and try to associate a picture to it by either double clicking it or using the browse button in the Draw palette.
I have looked in my install directory and the "FileSystemBrowser.dll" file is present as well as the "ImageFileBrowserIDL.dll" file, so what gives?
Running LiveCycle ES2 9.0.0.2.20120627.2.874785

Hi,
you should be able to fix that problem by re-registering Designer file browser DLL.

Help me to do this "IMAQ"-2 image file attached

Dear friends
In this i attach my image file in Tif format & jpeg format
Please go through this vi
this vi it will display a image window when u click inside that window a square box will create, where ever u click it will create multiple box. i used imaq windraw function, u can see another image window in the front pannel also.
now my aim is to put a box over that spot with the spot as center and to extract the pixel values of the individual boxes,
now whats happening is when i run this program a image window is opening from the imaq windraw function in that 1ly i can able to put multiple box but that box is displayed in the image display in the front pannel also. but i cant put the box in the image window in the front pannel. if u click the mouse in the image window in the front pannel it will display the 25x25pixel values.
i want both to be done in a same window i want to put a multiple square box and the pixel values i want to extract seperately for the individual boxes. please help me give some ideas how to do this please modify this vi.
thank u

Sasi,
I am a little confused on what exactly you want to do and why you are using both WinDraw and an Image Display Control to show the image. It sounds like what you want to be able to do are the following 3 things:
1) Display the Image
2) Click on the image and have a rectangle overlay appear on image
3) Get the pixel values from that rectangle into an array
If I am understanding you correctly, then you should only display the image using one of the above display methods and have only a signal case structure in your code that adds the overlay to the image AND extracts the pixel values. I am a little unclear as to why you have decided to only get the pixel values if the user clicks on the Image Display and only draw the rectangle if the user clicks on the WinDraw display.
I have attached an image of a block diagram, which is what I think that you are trying to do. In the block diagram you can see that I have combined everything into one case structure so that whenever a user clicks on the Image Display (no WinDraw) then I add a rectangle overlay to my image and also get the pixel values for that area. If you want to keep track of the pixel values for each rectangle then you could use a shift register and build up a 3-D array with all of this information ... or write the data to file ... or use another method to keep that data for future use.

Publisher hangs when I try to open an image file

Publisher hangs when I try to open an image file from:
right-click on image->Change Picture->Change Picture
The image is on my hard drive.
It also happens with powerpoint

Few Questions:
a. What version of publisher/PowerPoint are you using ?
b. Are you able to insert this image through Insert -> Image ? Image itself could be corrupt. Try to open it with some other editor ?

How to display a dynamic image file from url?

Hey,I want to display a dynamic image file from url in applet.For example,a jpg file which from one video camera server,store one frame pictur for ever.My java file looks like here:

Frame F=new Frame("My Applet/Application Window");
F.setSize(480, 240);
PlayJpg A = new PlayJpg();
F.add(A);
A.start(); // Web browser calls start() automatically
// A.init(); - we skip calling it this time
// because it contains only Applet specific tasks.
F.setVisible(true);
Thread count = null;
String urlStr = null;
int sleepTime = 0;
Image image = null;
// called only for an applet - unless called explicitely by an appliaction
public void init() {
               sleepTime = Integer.parseInt(getParameter("refreshTime"));
          urlStr = getParameter("jpgFile");
// called only for an applet - unless called explicitely by an appliaction
public void start() {
count=(new Thread(this));
count.start();
// called only for applet when the browser leaves the web page
public void stop() {
count=null;
public void paint(Graphics g) {
try{
URL location=new URL(urlStr);
image = getToolkit().getImage(location);
}catch (MalformedURLException mue) {
               showStatus (mue.toString());
          }catch(Exception e){
          System.out.println("Sorry. System Caught Exception in paint().");
          System.out.println("e.getMessage():" + e.getMessage());
          System.out.println("e.toString():" + e.toString());
          System.out.println("e.printStackTrace():" );
          e.printStackTrace();
if (image!=null) g.drawImage(image,1,1,320,240,this);
// called each time the display needs to be repainted
public void run() {
while (count==Thread.currentThread()) {
try {
Thread.currentThread().sleep(sleepTime*1000);
} catch(Exception e) {}
repaint(); // forces update of the screen
// end of PlayJpg.java
My Html file looks like here:
<html>
<applet code="PlayJpg.class" width=320 height=240>
<param name=jpgFile value="http://Localhost/playjpg/snapshot0.jpg">
<param name=refreshTime value="1">
</applet>
</html>
I only get the first frame picture for ever by my html.But the jpg file is dynamic.
Why?
Can you help me?
Thanks.
Joe

Hi,
Add this line inside your run() method, right before your call to repaint():
if (image != null) {image.flush();}Hope this helps,
Kurt.
