Password no longer works with encrypted disk image.

I have an encrypted disk image on my macbook pro. I enter the password every time I open the disk image. Last week it stopped accepting the password. I checked in keychain where I'd saved the PW when first creating the disk image and verified I was entering what was saved there. It matched what I've been entering but still no luck. I attenpted to pull an old version of the disk image from time machine and that still won't open with what I know is the password I've always used.
Any tips?

try doing SMC reset the following article tells how to do that:
http://support.apple.com/kb/HT3964
after doing this reset try again to enter the password for the disk image, if it still doesn't work there is no way to bypass the passcode on the disk. the following article talk about filevault:

Does it work with encrypted disk images?

Hallo,
I have a 10 GB fixed size image on my account and it is encrypted. It uses about 4,8 GB on the disk.
I would like to know if time machine is able to detect when changes are made inside such disk image,
if yes, if it is able to add just modified data or if it will copy all 4,8 GB file every time backup is made.
Thanks

If it is a standard encrypted disk image, Time Machine will copy the whole 4.8 GB every time.
But you can convert your disk image to a "SparseBundle" with this Terminal command:
hdiutil convert -format UDSB -imagekey sparse-band-size=32768 -encryption -o ~/Desktop/newimagename /path/to/olddisk_imagename (make sure that is all on one line)
That will copy your old disk image to a new one on the Desktop. A sparsebundle looks and behaves the same way as a regular .dmg. But the sparsebundle is actually a package that contains all of its data in 16MB bands. With any luck, your data changes will clump together in a few of these bands, and Time Machine will copy only those bands over rather than the whole shebang.

HT1578 Labels (Mavericks) not working in encrypted disk image?

I created an encrypted disk image with Disk Utility.
I placed a file in the opened encrypted disk image, and labeled it with "test".
If I open a finder window and look for files labelled "test" the file doesn't appear.
This message is placed under the wrong OS, because it is not possible to choose Mevericks from the popup list!!!!

Where I used the word label I did mean tag

File Vault on HOme Directory with encrypted disk image in it

I want to try File Vault. My question is as follows: I have an encrypted disk image already in my home folder. It is a small 500 MB one. Can I keep that in there, as is, without problems, or is File Vault going to encrypt and encrypted image and cause some sort of problem?
Has anyone done this without issues?
I know the alternative is to unencrypt my current image and let File Vault handle the encryption, but I am curious about leaving it alone and trying File Vault.
Thanks for any help,

FileVault is no more likely to scramble an encrypted disk image than it is to scramble the rest of your files. However, it is quite likely that it will scramble all of your files.
Has anyone done this without issues?
I have read many postings here in the discussion forums by people who have used FileVault and lost all of their data. Your mileage may vary. The only way I would use FileVault would be if I had an unencrypted copy of everything somewhere safe. Like you, I keep a small encrypted disk image for particularly sensitive files.

Printing Password NO LONGER WORKS with Snow Leopard!

Ive searched this forum and most people have the opposite problem I do. They want to disable password requests when printing, but I want them!
With Leopard, I was able to set up our networked color printer on every mac and students who logged in with their Active Directory accounts would then try to print but fail because they weren't part of the user group that were allowed to print to our color printer. When the password screen showed up, all I had to do was type in my account name and password, and the student's work would print. This was perfect for our lab set-up so we could supervise printing.
However, with Snow Leopard, this feature no longer works. The password box pops up but it doesnt matter what name/password is inputted, anything will print. By anyone. Yikes. My IT is not too happy and Im trying to find a way to fix this.
I saw Kiraly's tip on using Server Admin tools but it didnt work for us. Error 14071 something.
Any help would be greatly appreciated.

It could be falling back to Kerberos authentication, where passwords aren't needed every time. I'd suggest telling your IT people to disable kerberos on the Windows Server. If Windows is allowing users to access services with the wrong username and password, then that bug needs to be sent to Windows as a security vulnerability.
Otherwise, if they narrow it down to a problem on the Mac side, tell them to submit a bug to Apple.

Keychain passwords no longer work with lion

When browsing after upgrading to Lion, many of my passwords don't work any more. When resetting a password for a site, I usually get a dialogue box to the effect "that password has been used recently, please select another." The next time I log into the same site, I'm likely as not to get the same message "password incorrect," and must reset to a new password. It gets old, and keeping track of the new passwords is a hassle. I believe (but don't know) that key chain is responsible, but ...
Any ideas?

Had the exact same issue with my mini. I just reset the keychain. Basically removing all keychaines or saved passwords and starting over with having saved passwords for websites and system applications. If you go to Keychain Access in your Application's utility folder (easy: spotlight search keychain) then select File in the Menu Bar and then Delete Keychain. Those alerts for passwords will now go away.
**Added Note** This will delete all saved passwords. You just have to save them by entering them again.
Hope this helps.

Problems with ecrypted disk image

I'm trying to restore my laptop (Titanium DVI) from an encrypted disk image, and am having no luck. I have my laptop in target disk mode hooked up to a Mac Pro with the backup disk image.
When I use Disk Utility and attempt a restore, it prompts me for the disk image password, and it starts copying (and apparently succeeds in copying some items). But then after only a few seconds, it prompts me for the disk image password again, and I enter it again, and then I get an error 2, no such file or directory and it dies. After this subsequent attempts without rebooting result in error 16, Resource busy. Finder shows no disks mounted, but a ls of /Volumes shows that there are in fact copies mounted there. unmounting them from the command line does not clear the resource busy problem, but rebooting does.
I thought maybe the encryption is confusing things -- support for this seems sketchy. There seems to be no provision with command-line asr to deal with encrypted disk images. Also, hdiutil can do some things, but for instance I can't use convert to read the old disk image and create a new one, because it tries to apply the -stdinpass option to the new image, not the old one. I'd like to try making an unencrypted image to see if that is causing the problem.
edited to add that I'm doing an erase restore.

You choice. Since the immediate problem's was solved, you might want to start a new thread on the diskutil issue in the Unix forum: http://discussions.apple.com/forum.jspa?forumID=735 and start a new one in the Using Mac OS X Tiger forum on any Disk Utility issues.

How does one save new files to an encrypted disk image?

I encrypted a particular folder, and used a sparse image to leave plenty of room, as well as using read/write permissions, but I don't see how to save new files to the encrypted folder.

So, I guess you have to save the file to the desktop and then drag it to the mounted disk?
No, you should be able to save directly to a mounted disk image via a dialogue box. There is no need for an intermediate step. As long as the encrypted disk image is mounted, it is open and appears to be just another folder.
As an experiment, open a Textedit document and save it to the mounted (open) disk image via Save As in Textedit. It should be able to do that.

Encrypted disk image no longer demands password

Some time ago I created an encrypted disk image for storing sensitive data. It has been working fine for months, everytime I clicked on it it demanded that I enter the password before it mounted. But suddenly yesterday it stopped demanding he password and would just mount upon clicking. Tried restart, no change. Tried repairing the disk permisssions, no change. In the meantime, I have created a new encrypted disk, moved all the info to that, and secure-trashed the old one. But this gives me pause for thought. Not terribly secure! Anybody know what might have happened? How can an encrypted disk suddenly become unencrypted?

No, there's no other explanation, unless someone tampered with your account. Launch the Keychain Access application and look for a password item in your login keychain with the name of the image file.

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.

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!

Help: My password no longer works, and I am unable to log in with my Apple ID

I have a macbook pro, and it has failed to start up for a few months until now. When I get to the log in screen, my old password no longer works. When I then try to reset it using my apple ID and password, an error message appears saying it cannot connect and to check my internet connection, but it gives me no option check or change the connection when this window is up. Additionally, I have tried going into recovery mode and restoring from a backup I have on an external drive which did not work, and reinstalling Yosemite all over again, but I get a message that the disk is encrypted and asks for the password (again, a problem).
If anyone has any advice on something new I could try I would greatly appreciate it!

Hi chc517,
I'm sorry to hear you are having issues with your MacBook Pro. I also apologize, I'm a bit unclear on a couple things about your specific configuration. The message you mentioned about the disk being encrypted would seem to indicate that you may have File Vault enabled. If that is the case and you are having a login issue, you would need to use the File Vault recovery key to reset your login password instead of your Apple ID, as noted in the following article:
OS X Yosemite: FileVault recovery key

Encrypted disk image sometimes mounts without password

I have an encrypted sparsebundle disk image containing sensitive information. On occasion (maybe one time out of ten), I'm able to mount it without being prompted for the password.
The password for the image is not stored in my keychain. Can anyone offer advice on this issue?

I was having exactly this same problem!
I keep a small encrypted disk image storing sensitive banking information. I do NOT have the option to store passwords in Keychain checked, and I verified that the password is not being stored in Keychain.
Yet, when I double-clicked the supposedly encrypted sparsebundle disk image, it opened right up and mounted - no password required! Unbelievable, right? So I started to investigate.
I first noticed this behaviour in Mountain Lion, I'm running 10.8.4 on a 2.7 GHz 15" MBPr.
In past versions of OS X I would mount the volume to work on it by double-clicking on the disk image, enter my passowrd, and then Eject the volume either by dragging to the trash or clicking the Eject button on the Sidebar. The next time I would try to access the disk image by double-clicking it, it would again prompt for a password. All good.
What seems to be happening in ML is, using the same workflow, even though the volume is disappearing from Finder, the disk image is not actually being unmounted!
When I go to Disk Utility, the disk image is still mounted, but the volume is grayed out. When I Eject the disk image in Disk Utility, it then reverts to the expected bahaviour, and double-clicking on the disk prompts for a password.
So the workaround seems to be when finished working on the volume, go to Disk Utility and manually Eject the disk image (as opposed to just the volume it mounts) to ensure it has unmounted and is thus again encrypted. The reason for it sometimes requiring a password, sometimes not is probably because after a restart of the computer it would unmount all disks, and then be unable to re-mount it until the password is entered. But in between, unless you were aware of this behaviour anyone with access to the disk image can view its contents.
What a terrible security flaw IMO, as there is no visual indication in Finder that the disk image is still unprotected after you unmount its volume and that icon disappears! I'm surprised this hasn't gotten more attention.
Incidentally brian_c, I tried to look at your linked videos but it returns the message that the videos violated the TOS of the site...?

Encrypted disk image with recovery key

I am trying to create an encrypted disk image that can also be recovered with the use of a key. It is basically trying to do what FileVault does where you have a password to get in, but there is a Master password that can recover the image if you forget/lose your password. I have pieced the basic concepts together, but it isn't working. First I create the certificates that I believe I need with a keychain using the certtool command.
certtool y c k=SecureKey.keychain
certtool c k=~/Library/Keychains/SecureKey.keychain o= SecureKey.cer
I went with the RSA 1024 bit and SHA-1 stuff (that is the technically term for it).
After that, I tried creating the image. I am in the same directory that the SecureKey.cer file is in, so that shouldn't be an issue. Also if it can't find the certificate, it tells you that. Here is the command I used.
hdiutil create -encryption -certificate SecureKey.cer -stdinpass -type SPARSE -fs "HFS+" -volname TestVolName -size 20g TestImage
and that returned
hdiutil: create failed - error 0x8001184e
Does anyone have any thoughts on what I did wrong? Thanks.

Hi Robert,
> Once you through a sudo in there, you lose the option
to have a regular user
   That's not really true. Sudo is one of the most flexible commands around and not only can a regular user use it but they can use it without a password. Mind you I'm not suggesting that you make all users admins; you can specify both of these privileges for this command only. All you have to do is to put a line like the following in your /etc/sudoers file. (with sudo visudo of course)
ALL ALL = NOPASSWD: /usr/bin/hdiutil create -encryption -certificate*-stdinpass -type SPARSE -fs "HFS+" -volname-size
I've included wildcards so that the cert file, volume name, size and image are arbitrary but the others must be in the user's command to qualify. I realize that you'll want different options to use FileVault certs but I don't know how to do that so I used your original example as my example.
   Of course it wouldn't be that easy for your lusers to get all of those options correct so the next thing you do is to wrap the command, with it's sudo preface, in a shell script that parses the cert file, volume name, size and image from the options the user passes to the script and puts those into the command with the right syntax. If you want to get really fancy, the script could prompt the user for any arguments that were omitted. Your lusers will think that you created this really cool command and never know that sudo was involved.

Unable to unlock encrypted disk images created with Snow Leopard using Lion

Anyone else unable to unlock encrypted disk images created with Leopard and Snow Leopard with Lion? I know that they made changes with the release of FileVault 2 on Lion and Snow Leopard cannot use Lion encrypted disks but I thought it was backwards compatible where Lion should still be able to work with Snow Leopard created images (it was in the pre-release versions of Lion).
When attempting to mount an encrypted disk image created with Snow Leopard on Lion the normal password prompt appears but then just reappears every time the password is entered and does not unlock and mount the image. I'm positive the correct password is being entered and it works just fine when done on a machine running Snow Leopard.

Not in cases when the computer successfully boots to one OS but produces three beeps when an attempt is made to boot it to another. If it really was a RAM problem that serious, the computer wouldn't get as far as checking the OS version, and it has no problems booting Lion. In the event of a minor RAM problem, it wouldn't produce three beeps like that at all.
