An encrypted disk image is a file that contains all the data from a physical disk, but is encrypted so that it can only be accessed with a specific password. In OS X, you can create an encrypted disk image using the Disk Utility application.
When you create an encrypted disk image, you will be prompted to choose a password. This password is used to encrypt the disk image, so that it can only be opened with that password. Be sure to choose a strong password, and remember it, as there is no way to recover the password if it is forgotten.
Once the disk image is created, you can mount it just like any other disk, and access the files stored inside. The disk image will appear as a new drive in the Finder, and you can copy files to and from it just like any other disk. When you unmount the disk image, the files will be inaccessible without the password.
Encrypted disk images are a good way to store sensitive data, as they provide an extra layer of security. Even if the disk image is stolen, the data inside it will be safe unless the thief knows the password.

Why should you encrypt your disk image?
One of the most important aspects of data security is ensuring that your data is protected from unauthorized access. One way to do this is to encrypt your data. Encrypting your data ensures that even if someone were to gain access to your data, they would not be able to read it.
There are many different ways to encrypt your data, but one way is to create an encrypted disk image. An encrypted disk image is a file that contains all the data for a virtual disk. The data in the disk image is encrypted, so that even if someone were to gain access to the disk image, they would not be able to read the data.
Creating an encrypted disk image is a good way to protect your data, and it is relatively easy to do in OS X. In this article, we will show you how to create an encrypted disk image in OS X.
First, you need to open the Disk Utility application. You can do this by opening the Applications folder, and then opening the Utilities folder. Then, double-click on the Disk Utility icon.
Next, you need to select the File menu, and then select New > Disk Image from Folder.
A dialog box will appear, asking you to select the folder that you want to create the disk image from. Select the folder, and then click Choose.
Another dialog box will appear, asking you to choose the format for the disk image. Make sure that the format is set to Read/Write, and that the Encryption option is set to AES-256. Then, click Choose.
You will be asked to enter a password for the disk image. Make sure to choose a strong password, and then click OK.
The disk image will now be created, and it will be encrypted.
