How Secure Is A Disk Image Using AES-128 Encryption ?

I want to make encrypted disk images using Disk Utility.
How secure will they be ?
Good enough for state secrets ?
Can the encryption be broken ? If so, how easily ?
Could the average hacker break it easily or with great effort over a long period ?
Or would it take a team of government type experts ?
Ian the Paranoid.

I would say encrypted disks are a safe option.
However, with the coming rise of quantum computers, in the wrong hands, encryption for the near future will be all but nullified.
Some safe measures to take for making your computer safer include: Changing your router's password, enabling firewall, reverse firewall, FileVault (make sure you don't lose your paswords) Firmware password, encrypted mail service, (If available from your ISP).
These are just some of the obvious. There's more and I haven't used them all. But, it just helps to be informed and work with what you can.

  • How do you create a disk image using Disk Copy?

    Hello,
    Is there any way you can create a disk image using Disc Copy? Is there a better way to create a Disk Image?
    I would like to burn two copies of a 4.2 gig folder on my mac. I usually insert a blank DVD-R and then the mac asks if I would like to prepare it at which point I click "yes". An icon of a DVD disk appears on the desktop and then I drag my files onto this icon. It takes a few moments to create the disc image and then I click "burn". However, after the disc is burned the disc image disappears and I have to start all over again if I want to make another copy.
    How can I save this disc image? If I could save the disc image, it would enable me to burn a second DVD right after the first without having to create the disk image all over again. This would save a lot if time.
    I am using OS 10.1.5
    Thank you for any suggestions

    Thanks Niel for the info about creating a Disk Image with the Disk Copy utility in OS 10.1.5
    That worked however when I insert a blank DVD-R, the disk image still has to be copied to the DVD-R buffer and then it can be burned. And so this doesn't really save any steps - the "copying into the buffer" step still has to occur whether or not you have created a disk image of your files. So creating a disk image doesn't really shorten the process of burning multiple copies of a DVD.
    I will try to describe the steps more clearly:
    Two of the three steps for creating a DVD (steps 2 and 3) are very time-consuming:
    1. put blank DVD into the drive (a DVD disk icon quickly appears)
    2. drag files onto this icon (this step takes a long time as the files are copied into the buffer)
    3. choose "burn" (the actual burning also takes a long time)
    I was hoping that when I create two or more DVDs of the same files, I could first create a Disk image so that when I create the second DVD, step 2 could be skipped. That does not seem to be the case - the disk image still has to be re-loaded. And so I think I will not bother with the Disk image idea - it doesn't seem to be necessary or helpful when burning DVDs to backup data.
    Thanks for your suggestion.

  • How to create dvd/cd image using super drive in MacBook Air

    I have MacBook Air and also Apple Supper drive for the same. can u help me to find dvd/cd burrning and copy software. and also guide me "how to create dvd/cd image using super drive in MacBook Air"

    First to create a video DVD you need to use DVD authoring software like iDVD.  You can purchase it from the online Apple Store while supplies last.
    For creating a disk image use Disk Utility.
    To burn items to a CD or data DVD just insert the disc in the optical drive and drag those items onto the disc icon on the Desktop.  Then drag the disc icon to the Trash icon in the Dock which changes to a Burn icon.

  • Can I recover an AES-128 encrypted disk image from the 'trash'?

    I am a college student and I created an AES-128 encrypted disk image file (.dmg, .sparseimage) to store all my assignments and things. Unfortunately, while cleaning out my computer, I accidentally put the file in the trash without noticing and then proceeded to empty the trash. I then turned to the application 'MacKeeper' and used it's 'undelete' function but I could not find the file. It is very very important that I recover this file. I desperately need help.

    You might have better luck with something stronger.....

  • How to print uspto patent images using Safari and Quicktime

    3/18/06
    Do you want to know how to print US patent images using Safari? Read on.
    When you access the "images" link of a specific patent on the www.uspto.gov/ website using Safari, the page you are viewing is only one small upper left tile of a huge patent image that is not sized to the screen. You can scroll and try to read the page but it's almost impossible. Try to print it out and you only print what's on the screen. Bummer.
    The fix:
    Place the cursor on the opened image (it may appear blank), hold down the CONTROL key on you keyboard and click on the image. Two instructions come up. Click on the "Save Image to the Desktop" instruction and a DImg.tiff file will be created on your desktop. Click on the .tiff file and it should open in the Preview program, then simply print out the image. Voila!!!!
    Click the yellow arrow in the left margin to access page 2 of the patent and repeat the previous instructions to create another .tiff file on your destop. Do every page and you'll have the patent available to print out one page at a time.
    You can then rename the files and create a folder for that specific patent so you can access it later without signing onto uspto site.
    It's odd that the ever compatible Apple does not provide seamless compatibility to view and print patent images on the US Patent and Trademark Office's website. Where would they be without protecting their own intellectal property? Let's hope the next version of Quicktime includes the appropriate ITU T.6 or CCITT Group 4 (G4) compression language.
    Even the "throw it out the Windows" operating system is up to speed on this issue for America's hard working inventors.
    Keep on inventing.

    Hi Nick, I do see information on creating a slideshow with Quicktime at: http://www.apple.com/quicktime/tutorials/slideshow.html
    however it appears Quicktime X removed that capability. There is no 'open image sequence' option from the File menu in Quicktime X.
    If I do end up sticking with Final Cut - would you recommend any codec and/or dimension size that would result in the best quality or the most crisp image? I also need a few fade in's and out's on various parts - I don't believe I would have the control without Final Cut.
    Would resizing the image files in Photoshop to 1920 pixels by 1280 before importing them into Final Cut result in crisper images? Thanks.

  • I would like to know how to stretch a background image using HTML

    Hello Seniors of Sun,
    I gota small doubt in HTML, can any one please help me in solving it,
    I would like to know how to stretch a background image using HTML? I have tried and tried to figure this out and cannot..
    so any one kindly help me in this...
    waiting for reply...

    Please note that this is not an HTML forum.
    You can use an image tag on a DIV positioned behind the rest of the page, so that could actually work. And if you want to use body:background, then look up an HTML/CSS reference and see if there are any other body attributes or CSS stuff that applies to the background image.

  • Image display - How do I display an image using an absolute path?

    How do I display an image using an absolute path in a compiled WebHelp?
    Our developers use RH8 map IDs within our in-house applications to display in a model window created using Telerik Rad Window.
    Unfortunately images disappear from these model windows because RoboHelp removes absolute links to [inserted] images and changes them to relative in the compiled WebHelp.
    How do we overcome this? Is there a solution in RH8?

    I have tried again and changed the path in the topic HTML
    from : ..\..\HelpTopics\Icon_Search.png
    to    :  \HowDoI\Help_CMS\WebHelp\HelpTopics\Icon_Search.png
    I am obviously unable to see it in RH8 as I have removed the relative link so it is "outside" of the project.
    This time, on compilation, it has not stripped out the absolute links. The developer was working with me on this last week and we did have any issue in that they did not hold the absolute link. Most odd!
    Checking the published help it appears to be working in the application, which is great.
    So my apologies for raising the issue but it really did not work last week.

  • How do I change the image used on an movie project icon? iMovie seems to select an image at random from the images I imported.

    How do I change the image used on an movie project icon?
    iMovie seems to select an image at random from the images I imported.

    Not sure I understand how to use what you have posted. Here's what my init() looks like:
    public void init()
    setLayout(new BorderLayout());
    p=new Panel();
    p.setLayout(new GridLayout(1,1));
    callnowButtonURL = getURL(callnowButtonFilename);
    if (callnowButtonURL != null)
    callIcon = new ImageIcon(callnowButtonURL,"call");
    endcallButtonURL = getURL(endcallButtonFilename);
    if (endcallButtonURL != null)
    endIcon = new ImageIcon(endcallButtonURL);
    b=new JButton(callIcon);
    b.setBorder(new EmptyBorder(0,0,0,0));
    b.setBorderPainted(false);
    b.addActionListener(this);
    p.add(b);
    add(p,"Center");
    Now the ActionListener is basically:
    public void actionPerformed(ActionEvent e)
    if (mybool == false)
    <Perform actions here set mybool to true>
    Change JButton b to use EndIcon
    else
    <Perform actions here set mybool to false>
    Change JButton b to use CallIcon
    Can you clarify how to perform the action I require? You can have a couple of Dukes if you can help me sort this out.

  • CMAC using AES-128 MAC algorithms

    I am interested in IDL(International Driver's License) Applet
    And,
    I want to konw how to implement CMAC using AES-128 MAC algorithms in JavaCard 2.2.1, especially, JCOPv2.4.1.
    Does Java Card API or JCOP API support this algorithm, CMAC using AES-128 MAC?
    if not, do I should implement this algorithms as a function inside IDL Applet?
    please help me.

    JCOP v2.4.1 supports AES. You just need to code down what is written in the spec.
    JCOP platform itself does not support AES based secure channel protocol (SCP03).

  • How do I copy a disk image using disk utility?

    I have a copy of my idvd as a disk image, but when I open disk utility to burn it to a disk, I can't drag the destination disk to the destination box. What am I doing wrong?

    To create an image file, launch Disk Utility and select File: New: Disk Image From Folder. In the window that appears, navigate to the desired folder and then click on Image. Give the image file a name, and click on Save when prompted. That’s it.

  • Security Hole? disk image passwords are cached for a short time!

    Here's my experiment:
    1. Make a password-protected (128-bit AES) disk image (dmg or sparseimage), and do not save the password in the keychain.
    2. Load the image (you'll be prompted for the password).
    3. When virtual disk appears, eject it.
    4. Repeat steps 2 & 3 rapidly until the disk loads without first prompting for the password.
    Once this happens, it will (often) load again even after 10 or 30 seconds (or more?) without a password prompt..
    I don't see how this could be happening unless the password accepted by the prompt is saved somewhere.
    Why should it be? Where? Is there a bug?
    And why should it be saved as long as ten seonds or more after the disk is ejected??
