Administrative Unlock Utility (CMGAu)
This utility allows access to User, Common, or SDE encrypted les on a slaved drive, a computer booted in a pre-installed environment, or
on a computer where an activated user is not logged in.
This utility uses the following method to download a key material bundle:
• Forensic Mode - Used if -f is passed on the command line, or if no command line parameter is used.
• Admin Mode - Used if -a is passed on the command line.
Log les can be located at C:\ProgramData\CmgAdmin.log
Work Oine With a Previously Downloaded File
If you choose to work oine with a previously downloaded le, CMGAu works the same way, no matter how you launch it, meaning the
operation is the same whether you double-click the .exe to launch the utility, launch it without any switch in a command line or launch it
using the -f switch in the command line.
1 Open a command prompt where CMGAu is located and type cmgau.exe.
2 Select Yes, work oine with a previously downloaded le. Click Next >.
3 In Downloaded le, browse to the location of the saved key material. This le was saved when using the Administrative Download
Utility.
In Passphrase, enter the passphrase that was used to protect the key material le. This passphrase was set when using the
Administrative Download Utility.
Click Next >.
A message displays, indicating that the key material was successfully unlocked. Files are now accessible.
4 Once you are nished working with the encrypted les, click Finish. After you click Finish, the encrypted les are no longer
available.
