Enter a password when prompted. This is the password you will enter to unlock the disk image. It should not be the same as your Mac password. Make sure it is sufficiently difficult to guess. In the “Image Format” menu, choose “read/write” to allow you to add files to the image. Otherwise, you will only be able to view the files on.
To restore a backup you simply boot from a Macrium rescue disk, locate the image file and enter the password you set up for the backup job, and the image is decrypted and restored to your hard disk.

Here is a guide on how to create encrypted disk images in MacOS to backup or store files in a secure fashion.
When we store data on our Mac computers, we predominantly place it on our hard drives or on an external source. There are also online options available for storage such as DropBox or Carbonite, all of which have various benefits.

Here are the steps to create an encrypted disk image to store data in.
Creating Encrypted Disk Images
In order to create a disk image to use, we will need to use the application Disk Utility. Disk Utility is a great tool for disk diagnosis and getting helpful information about your hard drive. when you open the Utility, you will navigate to the File Menu, then click New Image and then Blank Image.
Creating a new blank image will essentially allow you to digitally allocate hard drive space for a specific usage, such as storage or privacy of your data. The next screen will give you all of the options for your new disk image including name, partition scheme, and encryption.
Name your new Disk Image what you would like, choose where it will reside and then designate the size and then choose your encryption. Encryption is the first line of defense against anyone trying to break into your files and Apple provides both 128-bit and 256-bit AES encryption for their disk images. Both encryption levels authenticate withapassword so create a password that is difficult to guess yet easy for you to remember. It can also recommend a password for you by clicking the key icon and opening Password Assist.
After you create your password, you will be able to save your disk image and begin dragging content to it. You will see your image as an external disk media with the name you designated. You will be able to copy files to it just as you would any other external drive and when you are finished, eject it by dragging it to the Trash.
The difference however, is that your image is still on your computer and can be moved around because it itself is a file. If you need to open and access your image again, double-click it to launch the password input screen and you will then see your disk appear on your desktop or in your sidebar.
Disk Images are an excellent resource for creating copies of discs or hard drives yet can be very useful for creating a safe place for important or confidential files. These disk images can be created at your convenience as long as you have the available disk space on your hard drive or target drive to create them. Next time you need to backup important files, think of creating your own personal safe to store them in.

Looking for a way to encrypt a folder of sensitive data on your Mac? You could encrypt your entire hard drive using File Vault, but this may be overkill for most people. Luckily, OS X has a built-in feature that allows you to create an encrypted disk image containing whatever data you want inside the image.
The only way to open the disk image is to enter the password. You can copy the disk image like a normal file and it will be unreadable unless unlocked on a Mac. Overall, it’s like creating your own encrypted file container.

Create Encrypted Disk Image
To create the disk image (DMG) on your Mac, first create a folder that includes all the data you want to encrypt. Note that once you create the disk image, the original unencrypted folder will still remain on your system and you should delete it immediately.
To get started, go ahead and open Disk Utility by going to Applications or by clicking on the Spotlight icon (magnifying glass) at the top right and typing in Disk Utility.
Once Disk Utility is open, go ahead and click on File – New Image – Image from Folder.
You’ll now have to choose the folder that you would like to encrypt as a disk image.
Click Open and you’ll get the Save As dialog where you have to give your new image a name and choose from a couple of options.
By default, it’ll save the new disk image in the same folder that you are encrypting. Under Encryption, you can choose from 128-bit or 256-bit AES encryption. The latter will be slower because of the stronger encryption, but your data will be better protected. When you choose any of the encryption options, you’ll be asked to enter a password.
Make sure you enter a very long and strong password because this is the only security that protects your data. If a hacker gets a hold of your file, they can try to use a brute-force attack to determine the password. Anything over 12 characters with letters, numbers and symbols will take a very long time to crack even on a really fast computer or cluster of computers.
For Image Format, you can choose from read-only, compressed, read/write, DVD/CD master or hybrid image. For our purposes, you should choose either read-only or read/write. If you choose the latter option, you’ll be able to add more files/folders to your encrypted image at a later point.
Click Save and your new image will be created. Note that if you chose 256-bit AES encryption, it could take quite a while for your disk image to be created.
Now when you go to open the image file, you’ll get a prompt asking for the password. Deskbot deck. Make sure you do NOT check the Remember password in my keychain box.
If you enter the password correctly, the image will be mounted like a drive and if you chose read/write for the Image Format, then you can add or remove items from the encrypted image just like a normal drive. When you add something to the drive, it will automatically be encrypted and protected.
