Password protected , encrypted disk images

There are times when you may want to keep files away from prying eyes. A great way to do this straight in OSX is to make an encrypted image that you can mount and write to. So first open up disk utility. I am going to create an image on a usb drive so that I can take it with me.

As you can see I have made a partition called test. Highlight the partition then goto File –> New –> Blank Disc Image

Select the Save as and give it a name, You may also give the volume a name but it is not necessary.

Choose volume size and select custom, enter a size smaller than what the volume in question can hold ( as you see in the video I choose 1.8 GB). Select the encryption type, the partition should be changed to harddrive and the image format should be changed to sparse image.

Click create, it will ask you for a password. When you hit create it will start the process and automount the image for you. It will not ask you for a password because it will have saved it to your keychain.
