Can a 256 bit encrypted disk image be read by Tiger?

I have computers running Leopard, Tiger and Panther.
If I create a 256 bit encrypted disk image in Leopard, will the image be able to mount and used for reading and writing in Tiger and or Panther?
Or should I use 128 bit encryption in a mixed OS X environment?
TIA,
Bill

Hello Bill,
A 256 bit encrypted disk image created in Leopard can be opened in Panther, and presumably Tiger, though I don't have Tiger.
It cannot however, be written to, only read.
So if you want to add to the disk image on Panther, and possibly Tiger, use 128 bit. But if you only want *read only* on the other machines you could use 256 bit.

  • Can you resize a encrypted disk image on a sparsebundle disk image?

    I created a 50GB encrypted sparsebundle disk image on my desktop. I named it BOB and also named the encrypted disk image BOB.
    It's now full.
    I've just made it 60GB with Disk Utility.
    I opened it but on trying to copy a 4GB file into it, I got a message saying my sparsebundle disk image is too small.
    Note: Disk Utility says the following:
    BOB sparsebundle is 61.4GB
    mounted volume BOB is 52.1GB
    Hope that's clear.
    Any help would be most appreciated.

    I created a 50GB encrypted sparsebundle disk image on my desktop.
    hdiutil resize -size 60g BOB.sparsebundle
    Result: "resize failed. File or directory does not exist"
    You need to tell hdiutil where to find the target BOB.sparsebundle file. You could either specify a relative or absolute file path in the command itself, or else you could first change the current working directory to the Desktop. So if you wanted to pursue using Terminal, the second way would be to enter this command:
    cd ~/Desktop
    and then try the same hdiutil command again.
    I'm not familiar with the hdiutil command, and I don't know if the above would work. My own feeling is that trying to manipulate an image file by experimenting with hdiutil entails a risk of corrupting the image file and losing its contents, and it is therefore essential to back up the image file first. But if you are going take the time and space needed for a backup, you might as well instead just create a new, empty 60GB (or larger!) sparsebundle disk image, and copy the contents of your old disk image into the new one. This would not involve any risks, and you'd end up with the larger disk image that you wanted. You could then delete the original, if you wished.

  • Writing to Encrypted Disk Image SLOW On Mac Pro

    I have a slew of Previous Gen (2010/2012) Mac Pro 12-Core 2.66 desktops running 10.8.5 (12F45). When making a standard 128-bit Encrypted Disk Image, the write speed to that image is extremely slow. Disk image is on the same system internal drive as the source material. Also tried on Gigabit Ethernet share. 1GB file takes 20 minutes.
    If I take the same disk image and run it on a 2012 Mac mini server 2.6 i7 running 10.8.5 (12F45), the write speed is fast; 1GB takes 1 minute. Same holds true for a MacBook Pro (non-Retina) 2.3 i7 running 10.8.5 (12F45).
    Antivirus is disabled on all machines for testing purposes. Mac mini is actually a clone of the Mac Pro's system, so everything is the same, software-wise.
    Is there something inherently wrong with these Xeon Mac Pros that they cannot write fast to encrypted disks? Any other variables I'm not thinking of?
    Thanks in advance.

    The write speed to an encrypted image is around 5.65MB/s in comparison to 92MB/s on normal disk. I feel frustrated to see the remaining time to copy 800GB of data from internal HDD to the mounted encrypted volume takes around 1 day. An encrypted disk managed by Truecrypt on any PC will work much better than it.

  • Can't paste password for new encrypted disk image.

    Howdy all!
    I have been trying to create an encrypted disk image with the Disk Utility, but I'm having trouble with putting in the password.
    Using the password assistant, it only fills one of the two password fields, and I cannot copy/paste the password to the other field. If I generate a password elsewhere I cannot paste it into either box as well.
    If I switch applications from Disk Utility and come back to the password dialog the menubar says I am still in whatever application I was last (in this case it says Firefox at the very left) and the Edit menu is completely grayed out.
    Any idea how to get a non-typeable password into this dialog?
    Thanks for your help.
    Mike

    You can paste it in if you use hdiutil to create or mount the disk image (In Terminal.app). That's the
    only way to go if you use a "bullet proof monster" password like I do.
    To create an encrypted, sparse disk image, open a Terminal window and cd to the directory in which
    you want to create the image file. For example:
    cd ~/Desktop
    Then type the command:
    hdiutil create -size thesize -encryption -type SPARSE -fs HFS+ thename
    live command example:
    hdiutil create -size 1g -encryption -type SPARSE -fs HFS+ myimage
    (this will create a 1gigabyte sparse image with the hfs format with the name "myimage.sparseimage"
    #note: I love sparseimages and sparsebundles because they mount so quickly#
    Above, the size is the maximum size that the volume will ever be able to contain, for example,
    660m for 660 megabytes or 1g for one gigabyte. Note that if you want the image file to remain
    below a certain size (such as the size of a CD) you must allow for approximately 10% overhead.
    Also above, thename is the name of the image file you want to create, not the volume name.
    The volume name will be "untitled". Rename as you would any other mounted volume (after it is
    mounted).
    You will be asked for a password or phase to secure your file. In terminal you may copy and paste
    or use command + V keyboard combo. It will mount normally after that.
    I don't use the "Remember password (add to Keychain)" function because my passphrase will be
    visible in the Keychain to anyone with physical access to your computer.
    Instead I use Terminal to open my new image.
    Open terminal.app, simply type:
    hdiutil attach /path/to/imagefile
    example:
    hdiutil attach /Users/kj/Desktop/myimage.sparseimage
    (remember, you can drag and drop the file path into the terminal from Finder)
    Terminal will ask for your password, simply cut and paste from your favorite password program
    (such as "1Password").
    There is a manual page available; type man hdiutil in the Terminal.
    Enjoy,
    Kj

  • Encrypted Disk Image - Can't find it

    I just created a 1GB encrypted disk image using the Disk Utility program on my macbook (Macintosh HD). After I created it, I put some files in it. Then I "ejected" it, logged off, and then logged back on. It is no longer on my desktop. I tried doing a search and still can't find it.
    So...how did I find it and how do I create a short cut so I don't run into this again?
    Regards,
    New Apple User

    To expand a little on Steve Sherriff1's answer: when you created the encrypted disk image in Disk Utility, it created a file with a .dmg extension, saving it wherever you specified (if you open Disk Utility and again select 'New -> Blank Disk Image' from the File menu, it should still be pointing to the last location you save to). That .dmg (disk image) file is opened as a virtual disk on the desktop when first created. When you eject it, it won't automatically reappear on the desktop; you need to find the .dmg file (using Steve's tip) and double-click the .dmg to mount the disk image. For easier mounting, you can put an alias to the .dmg file on the Desktop, in the Dock, or in the lower-left pane of your Home folder.

  • 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.....

  • Disk Utility create encrypted disk image hangs

    I'm trying really, really hard to backup my data but apple is not making it easy for me.
    I need my files encrypted for an offline backup. Time machine only allows home folder to be encrypted, and due to my home folder being on my SSD drive I cannot fit my files all in there, not by a long shot.
    Using Disk Utility, I choose "new disk image from folder", and select "read only", 256-bit encryption. Some of the folders worked. However some will just hang for hours on "Creating Image, copying...". I can see at the destination the dmg file has stopped incrementing larger. It has reached the full size of the folder approximately. Does apple fail at some file types? I already ran disk repair several times to no avail. I don't know what else to try, it just doesn't want to work. All I want is an encrypted backup, that any OSX install can retrieve without any special software involved. Sometimes I'll get a very unhelpful error message "Operation not supported". Whatever that is supposed to mean. Google was no help so hoping for some insights here.

    Create an encrypted sparse disk image instead of from folder, mount it, and then drag & drop your files into ii.

  • Unable to create an encrypted disk image with Disk Utility

    Hi:
    With our upgrade to Lion a few weeks ago, we're now unable to create an encrypted disk image of any type using Disk Utility any more. This problem occurs on 3 different machines, and is reproducible whether one is using an internal HD or an external FW HD. We can successfully create nonencrypted disk images.
    This is a duplicate post with all the details here: https://discussions.apple.com/message/18469359#18469359
    We haven't had any luck with a solution trying various permissions fixes as helpfully suggested by other readers in response to the error message # (-60008 error), so I'm hoping that someone else has run across a solution from the encrypted disk image perspective and that this tag line will generate some help.
    Thank you!

  • Insecure Encrypted Disk Image?

    Hello. For the first time, I'm trying to make an encrypted disk image using Disk Utility. I go to "New Disk Image from Folder", create the image using read-only and 256 bit encryption and all goes well: I've got a disk image.
    However, when I double click on it, it opens up without having to use a password. Is it supposed to work this way, and if not, what may I have missed to get a really secure disk image?
    Thanks for any help with this.

    You may have the password for the disk image stored in your keychain.
    I noticed when trying to make a test disk image in the manner that you describe, that the option to save the password in your keychain is enabled by default.
    To check, go to
    Applications > Utilities > Keychain Access
    and see if you have that password stored.
    If so, you can delete the stored password from Keychain Access.

  • DIsk Utility, encrypted disk image

    I cannot create an encrypted disk image. I have searched through the discussion forums here but have not found an answer. After I select the name, location, image format, encryption and I hit save, I get an error that says "Unable to create '[file name].dmg'. (Resource busy)". I've tried different locations, image format and encryption, but I keep getting the same message. Any ideas what the problem is and how I can fix it? Thanks.
    NB: I want to create the disk image so that I can encrypt a few files with sensitive information. I do not want to use filevault, as I understand that it has downsides (e.g., free space needed to turn on and off, and backup with TM).

    1. Open the Disk Utility application. (If you don't know where it is, search for it in the spotlight.)
    2. At the top of the Disk Utility window, you will see several icons. Click on the one labeled "New Image". Before you do this, make sure that none of the drives on the left column (including "Macintosh HD") are selected.
    3. A new window opens. It asks you for the name you want to give the new disk, and where you want to save it to (you can choose to save it on the desktop). It will also ask you for the volume size of the new disk (the default setting is 100MB, but you can give it any size you want). It also asks you for the volume format, encryption (128- or 256-bit; 128 should be enough, unless you want to make it more secure, but compromise a bit of speed), partition (there is no need to partition; in fact, many recommend no partition at all), and image format (if you plan to frequently add and delete files on your encrypted disk, "sparse bundle disk image" is recommended".
    4. Click "create". It will ask you to create a password for your disk image.
    5. The new disk image should appear on your desktop (or other destination you chose). Double-click on the image to open it. It will ask you for your password. Enter the password you selected. You can choose to save the password on your keychain. That defeats the purpose of encrypting the disk image, since anyone who gains access to your computer will not have to enter the password to open the disk image and see its contents.
    I hope this step-by-step guide helps you. Let me know if something is not clear or if I got something wrong.

    Unable to create "Volume.dmg." (error - 60008)
    I have previously, successfully, created encrypted disk images in Snow Leopard, and I don't know why I can't in Lion
    Does anyone have any ideas?

    Thanks for this Thomas.
    I've tried naming the image differently, but still received the error, I did however try different permutations for the password.
    The error seems to happen if I use a purely numerical password string and occurs on input of the 10th numerical character, if I start with numerical character but use an alpha before the 9th number I can continue and create a password, and I can create a password  if I start with an alpha and switch to numerals after the first alpha character, purely alphabetical passwords are fine too.
    It seems that Lion doesn't like purely numerical passwords greater than 9 characters, whereas Snow Leopard wasn't so fussy. Seems it's a bit of a bug.
    Thanks for your help

  • Disk Utility fails to create encrypted disk image

    When creating a disk image using 256 bit encryption and a purely numeric password longer than 13 characters the following message appears:
    Unable to create "ABC.dmg." (error -60008)
    the error happens upon typing the 14th consecutive number into the Password field. I have created images under the same conditions in the past, Not sure if this is caused by Lion.

    Looks like one of the drives is bad.
    While it passed being zeored with Disk Utility, it failed about 15 minutes into a 'Certify' using SoftRAID.
    Now waiting on a replacement drive from Newegg.

  • Encrypted Disk Image to Password Protect Folder Not Working!

    I have followed the instructions exactly for creating a Disk Image in order to password protect a folder.  Folder contains multiple types of files including images, pdfs, etc.  Here is what I've done and what happens:
    In Disk Utility I created a New Disk Image from Folder.  I chose the folder, which I have on my Desktop, and clicked Image.  I gave the Disk Image a new name, placed in on my Desktop, indicated the image format as read/write and chose the 128-bit encryption.  I chose a very strong password and unchecked the remember password box.  At this point, all seems to have gone well.
    Now, back to my Desktop.  I have two things going on.
    1. The initial folder that I wanted password protected is still present.  Am I supposed to just send this to the Trash?
    2. When I double click on the the new .dmg file that I've created, I am asked for my password, which I put in.  Then, nothing.  I mean, nothing happens.  It doesn't open, it doesn't do anything.  I can click on it and choose Open with DickImageMounter, and nothing happens.  I can open with Disk Utility, but this just gives me the normal options to eject, burn, restore, etc.
    I don't know why I can't get this to work properly, and I'm a little annoyed that Apple can't make it as simple as selecting a folder and having the option to password protect it, just like you can a normal file.  PLEASE HELP!
    Thanks.

    As of OS X 10.7.4, Disk Utility had a bug that prevented it from creating an encrypted disk image with a password of more than 10 characters. I haven't checked recently to see whether that bug has been fixed, but from your report it seems not to have been. There is a workaround, but it's complicated.

  • Any gotchas for encrypted disk images?

    I am about to set up e-bills and e-statements at various banks and credit cards and wanted to check a couple of things before doing something that may end up being bad
    The assumption I am going with, is I will create an encrypted disk image to store all the PDF's.
    1. Is that the right thing to do? Or is there a better way to keep the data secure?
    2. If I do so, what is the backup impact? Can I simply set up a task to copy and paste the entire disk image to my external drive?
    3. If I want to open the disk image on another computer, can I? How will it authenticate the user/pass on a different computer?
    4. I can backup an encrypted disk image to a FAT-formatted external drive?
    5. And finally, I have read disclaimers that if I forget the password the data is lost irretrievably. But also, that the password is stored in keychain. So if the password is stored in keychain, the worst-case scenario can only happen if I forget the master password, right? I don't need to truly remember the password to the disk image necessarily, right?

    Your profile info indicates that you're running Tiger. If so, post to those forums. If you're running Leopard, update your profile info. What are you trying to protect and from who? Is your computer secure?
    IIRC, encrypted disk image passwords are independent from Keychain Access. So if you forget it, then you're hosed. BTW, that's the major failing with encrypted anything. If you forget the password, you're hosed. If the disk image gets corrupted, it's useless with or without the password. Anything stored in an encrypted disk image needs to be backed up in an unencrypted state and stored in some kind of physical thing like a safe. Methinks your a bit paranoid. Disable auto-login, use high-level passwords (that you remember), don't enable the root user account or activate a master password, and you should be secured enough.
    I updated the profile. I am running Leopard. So this is the correct forum.
    What am I trying to protect? I thought I put it in the first line - statements from banks and credit cards.
    From whom? From unwanted entities who may get access to my computer, in any way.
    I didn't get the part about the safe. Can I or can I not back up an encrypted disk image to an external drive "as is"? What about possibly opening it up on another computer? And how about putting it on a FAT-formatted disk? I repeat my original questions, but for a reason - they seem to have not been answered.
    I do not have auto-login, and I remember my strong login password. I don't have my root account enabled. Under this scenario you think my data is going to be secure? What about if someone were to get control of my computer? Forgive me on this one, I am a switcher so there is a general paranoia about such things which I would like to clarify before reorganizing my life.
