Regaining access again will require the password before it can be mounted and available. The short video below demonstrates the entire process, in less than a minute you can encrypt a folder with password protection and mount it for access. Remember, do not forget the password, or else you will lose access to the data stored within the encrypted folder for good. This will only encrypt and password protect the folder specified, if you are looking for full disk encryption for literally every single thing on the Mac, you would want to enable FileVault instead.

But the original folder is still there will all the content, and this original folder is NOT encrypted!

Of course, you have to trash the original folder, otherwise it would be pointless. Good trick! The problem is that if you create a dmg from a folder of 10MB, the dmg has a maximum capacity of 10 MB and it is not expandable, and so it is not possible to add new files to the dmg. Or is there a way to do that? For an expanding disk image, you need to create a New Disk Image and specify the type as Sparse Bundle. You can choose to encrypt this and then you can copy stuff in to it. It will resize the image to hold the data.

I had an idea to encrypt whole home directory. I swtiched user to encuser and it worked as I expected. It was so much laggy so it was useless. Am I doing something wrong? On linux I can mount encrypted partition or loopback file and use it as my home directory with no problems. I also realized, when I had logged-out the user some of his processes were still runing. The built in File Vault feature turns the home directory into an encrypted disc image that is mounted and unmounted automatically. This is only true of Snow Leopard.

Lion and ML use Filevault2, which uses whole disk encryption, not just the Home folder. Making your Home folder encrypted is a pain and causes numerous admin problems for OSX processes. Either turn on FileVault or use an encrypted image for your Documents. If I use FileVault all of them would have access to the whole disk. Btw, there is a very basic security problem with dmg encrypted images. Consider your mac is confiscated in UK. You have a same problem with FileVault. All goes well to the point where I click on the newly created.

Obviously done something wrong but not sure what.

Back to the old way. I have been using encrypted disk image for long time; since OS Leopard. And I have no problem with it.

Hey what am I doing wrong. IT actually does nothing. WHat did I do wrong? Also can you use the same process to change the password on a protected folder. This is a terrific tutorial. You cannot use a crypted folder that way since you cannot add new files to the folder. You can add new files to the encrypted folder by unlocking the DMG and then copying files to it. If you intend on placing a lot of files in there, make sure to account for the growth in file size when creating the original disk image. You can also use Disk Utility after the fact to resize an image if necessary.

You can think of the encrypted disk image folder as a little virtual hard drive partition, it is set in size just like a partition but can be shrunk or expanded if necessary. This works great with one exception.

FileVault requires that you log in every time your Mac starts up, and no account is permitted to log in automatically. You can then turn it on again to generate a new key and disable all older keys. Decryption occurs in the background as you use your Mac, and only while your Mac is awake and plugged in to AC power.
