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.....

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.

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

Can I recover a deleted email that is not in the Trash?

Can I recover a deleted email that is not in the Trash?

If you have a recent backup yes. Or, possibly, if you do not use your computer at all (so the hard drive is not written on) and get some recovery software or company to try to see if the file is retrievable (not cheap). Other than that, unfortunately not.

Encrypted disk image from ****

So i made an encrypted disk image and forgot the password.
The disk image:
Size: 100 mb
Format: Mac OS X Extended (Journaled)
Encryption: 25-bit AES
Partition: Single partition-Apple partition map
..and no, i didnt save the password on my keychain
...(you can stop laughing now :P )
I´ve been in contact with Apple Care and we spent about 3 hours trying loads of things with no luck.
I know im more or less f*ed, but i know there is a lot of smart ppl on this forum.
If anyone has idea, no matter how crazy, im willing to try it.

Hi Worm76;
My suggestion is forget about what was in the encrypted disk image. Write it off as lost.
It would take someone like the NSA to get it back for you and I doubt very much that you have anything in there to interest them.

How do i recover a document that has been "emptied" from the trash?

I "emptied" my trash, which contained the word document of a file and unfortunately now all i have is the PDF version and I don't want to recreate the entire document. Any solutions to bring it back? I saw them do it on CSI one time!

With absolutely no guarantees you may find data retrieval software that may allow you to get the document back. You would have to stop using your MBP imediatly so that the document is not overwritten (which it already may be). No freebies in this department.
If this is worth big bucks to you, you can employ a data recovery firm that also with no guarantees may be able to recover it.
Time Machine alleviates all such problems.

Can I apply more than one keyword to images from the Control Bar?

I swear this used to work. I select multiple images in a project. I apply a keyword to the selection by clicking a keyword button on the Control Bar. It gets applied to all the selected images. I click another keyword - it gets applied to only the first selected image.

Michael, thanks for that quick response! Yes, that was it. Of course I don't know why I would have selected that option. It would seem to make sense to put this option in the Preferences instead of Edit - it would make it less easy to change accidentally.
Regards,
Francis.

Can't create encrypted disk image

With Leopard, I have repeatedly followed the instructions for using Disk Utility to make an encrypted disk. All appears to go well...all fields appropriately filled, including 128 encryption. But when I hit create, either nothing happens, or I get a second Disk Utility starting window. In any case, I am not asked to create a password, and am unable to find any trace of the disk I thought I'd just created. Would welcome your thoughts.

While creating, make sure that it's saved to the desktop so you will know where it is supposed to be, at least.. Was wondering if posssibly you lost them. Look for the named disks in your home folder and in HD on chance they are there somewhere.
I know you went to Help but just making sure you are creating disks this way (below). Everything worked fine for me--
If things still don't work, turn off DU and move to the desktop "com.apple.DiskUtility.plist" in your home folder/library/preferences. A new file will be created when disk utility is turned on again. Deleting plist files don't usually don't solve problems but sometimes they can become corrupted.
Good luck

1 choose File > New > Blank Disk Image.
2 Type a name for the image, and choose where you want to save it.
3 In the Volume Name field, type a name for the volume that appears when you open the disk image.
4 Choose the size of the disk image from the Size pop-up menu.
5 Be sure you choose a size that’s large enough to hold any changes and new documents you might add.
6 Choose an encryption option from the Encryption pop-up menu.
7 Use the default settings for the rest of the options:
8 Choose “Mac OS Extended (Journaled)” from the Volume Format pop-up menu.
9 Choose “Single partition - Apple Partition Map” from the Partitions pop-up menu.
10 Choose “read/write disk image” from the Format pop-up menu.
11 Click Save.
Enter a password, and click OK.
Disk Utility creates the disk image and mounts its volume on your desktop.
Copy the documents you want to protect to the volume.
If you want to erase the original documents so they can’t be recovered, drag them to the Trash and choose Finder > Secure Empty Trash.

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.

Encrypted Disk Image creation slow?

I just got a new MBP with Leopard. I have created a number of encrypted disk images in the past using Tiger and a MBP and have not had any trouble. This weekend I tried a few times to create a 50 gig encrypted disk image (128 AES) on an external drive and after going through the process of setting it up and waiting for it to be created, (and watching the progress bar as it was being created), after about 45 minutes NO progress was showing on the progress bar. I ended up having to cancel the creation a few times because I thought something was going wrong. I’m not sure if there is a problem creating the disk image, or leopard is slow, or what.
Does anyone know how long, on average, it would take to create an encrypted disk image of this size using leopard? I just want to know if there is a problem doing this on my MBP. Thanks for the help.

A regular 50 GB disk image takes 50GB of space, no matter if it is full of files or empty.
A 50 GB sparse disk image only takes up the amount of space equivalent to that of its enclosed files. So if the 50GB sparse image only has 1 GB of files inside, the image won't be much bigger than 1GB.
A sparse bundle is similar to a sparse image, but instead of a single file it is a folder package with many, many enclosed files called bands. A new file added to the sparse bundle will tend to modify only a few bands. This makes incremental backups of a sparse bundle more efficient because only the changed bands need to be backed up again. Any change to a sparse or regular disk image will mean that the entire image will need to be backed up again.
If you regularly add/remove files to a disk image, and you intend to back up that disk image with Time Machine, a sparse bundle is definitely the way to go. The other types will fill up your TM volume very quickly.

Corrupted files within encrypted disk images

Greetings Apple Hivemind:
I've run across a repeatable problem when using encrypted disk images from Disk Utility. Essentially, I'll create an image using settings like are shown below:
The disk image is then used for storing data. In my case, this is usually data for Adobe Lightroom.
At first, this worked very well, and I housed the disk images on my household NAS, connecting via samba (smb) to it on my Mac. Over time, however, something odd started happening: Files on those encrypted images began getting corrupted whenever I tried writing new data to them.
My first incident was where Lightroom informed me that the catalog it was trying to open was corrupted. I tried to create a new one on the same encrypted volume, and it too was instantly flagged as corrupted. I opened the individual image files on the volume with no problem, so I wasn't thinking that the volume was the culprit. That is, until I tried dragging new image files to it manually. The new files were immediately either completely unreadable, or a mish-mash of the content of random OTHER files on the volume!
The result was that all old data seemed intact, but I could no longer write new data to the volumes without major data corruption issues. I thought that this was isolated to one volume in particular, but it soon started happening on ALL of my encrypted volumes eventually. Including those which were not, and never had been, housed on my NAS, but were on my local hard drives.
I've since "evacuated" all my data from these images, since the ones created by Disk Utility appear to be useless, and am seeking an alternative.
Is this something that anyone else has encountered when using encrypted disk images? It seems like this is something I should really open a support ticket for, but I can't say I've ever tried it, so I don't know how successful it would be to do so.

I should add that I've tried using the "Repair" and "Verify" functions of Disk Utility on the volumes, and despite the obvious issues that exist in them, the utility doesn't find (or fix) any inconsistencies.
Are you repairing/verifying the actual disk images, or just the partition they're on? If the partition, it won't look inside them.
Drag one to Disk Utility's sidebar, select it, then use Verify or Repair. Note: the usual messages may not appear on the DU window. Click the Log icon in the toolbar or select Window > Show Log from the menubar to see them.

Indexing of encrypted disk images permanently disabled in 10.8?

In the past, I've had no trouble forcing Spotlight to index my encrypted disk image, using the command in Terminal:
sudo mdutil -i on /Volumes/Encrypted_Data
After entering that command, my encrypted disk image was indexed and searchable using Spotlight.
A couple weeks ago I updated from Lion to Mountain Lion. Today I noticed Spotlight wasn't showing any results from my encrypted disk image. So went back to Terminal and entered the above command. Instead of successfully activating indexing, Terminal gives me this message:
/Volumes/Encrypted_Data:
Indexing disabled.
Is this procedure now impossible in Mountain Lion?
Is there any way to enable indexing of this encrypted disk image? I can't get it to work.
Thanks.

I appear to have solved the problem to get Spotlight to index a disk image. My image was an encrypted disk image. I was able to get spotlight to work when it was new, but now Spotlight won't index it. Here is the solution that I found:
After double clicking and mounting disk the image, open Disk Utility, select the disk image file, then click unmount in the Toolbar. Wait until it is unmounted, then click mount again. Then go to terminal and try mdutil -sa . If it is still not enabled, try to sudo mdutil -i on option. The unmounting and remounting must be done everytime the image is opened.

Encrypted Disk Image mounts without Password

I've created a new encrypted disk image so that I can store sensitive documents and did it carefully, step by step,(per instructions from www.macworld.com/2425) but after I unmounted, then remount, it doesn't ask me for a password. It just mounts as if it were a regular file. Am I suppose to unmount the volume and drag the disk image to the trash? I don't know what else to try.

The Mac uses and encrypted database of keys called the "Keychain". When you login, it opens the "login" keychain using your login password. That keychain can be used to provide passwords for applications and services, and form data for web sites. In this particular case, the password for your encrypted disk image is being stored in the keychain and automatically provided.
If another user attempted to open the disk image, the disk image mounter would first look in his keychain and then the system keychain for a key to open it with. Finding none, it would prompt the user to specify the key (password). If the user supplies the correct password, the system would put it in his keychain for safe keeping, and the user would then be able to open the image again without supplying the password.
You can remove the key from your keychain by opening up /Applications/Utilities/Keychain Access, selecting the "login" keychain, and then looking for an entry with a name that matches the .dmg file in question. Highlight it, and then press the delete key to delete it. The next time you attempt to open it, it will prompt you for a password.
