Encryption

-------

hdiutil supports native disk image encryption using AES-256 (slower but stronger) or AES-128 (faster but weaker).  Enabling disk image encryption via create-dmg will require the entry of the password during the middle (compression phase) of the process.  Take care to enter the password correctly, because hdiutil will not prompt a second time to confirm the password.



Example

-------



```sh

#!/bin/sh

test -f Application-Installer.dmg && rm Application-Installer.dmg

create-dmg \

  --volname "Application Installer" \

  --volicon "application_icon.icns" \

  --background "installer_background.png" \

  --window-pos 200 120 \

  --window-size 800 400 \

  --icon-size 100 \

  --icon "Application.app" 200 190 \

  --hide-extension "Application.app" \

  --app-drop-link 600 185 \

  "Application-Installer.dmg" \

  "source_folder/"

```



See the `examples` folder in the source tree for more examples.



Requirements

------------



Nothing except a standard installation of macOS/OS X is required.



We think this works in OS X 10.6 Snow Leopard and later.



We'd like to keep it working in as many versions as possible, but unfortunately, we just don't have test boxes running old versions of OS X adequate to make this happen. Development and testing mostly happens in the last 3-5 years' worth of macOS releases; as of 2020, this means macOS 10.12 and later.



But if you find a bug in an older version, go ahead and report it! We'll try to work with you to get it fixed.



If you're running OS X 10.5 or earlier, you're SOL. That's just too hard to deal with in 2023. ;)
