I am just wondering if it's possible to set a password to existing dmg image. There is no such option at Disk Utility.

You can change it by first selecting the DMG in Disk Utilty. Then go to Images>Change Password.

Change Password - Disk Utility
It will prompt you for the password. prompt for password - Disk Utility
Then, it'll ask you for a new password for the DMG. New password prompt

@com File? It's under the Images menu, unless you have an older OS... –  daviesgeek Feb 2 '12 at 19:46

This does not seem to work under Mavericks though. The Images menu does not include the Change Password… item. What now? –  Aller Feb 11 at 23:53
    
@Aller, go to File->Change Password like the user above mentioned. –  Josh Beam Sep 19 at 15:05
