Programatically detect when decryption is done?

Created: 29 Mar 2013 | 2 comments

Hi all

I am trying to decrypt PDP 10.x encrypted drive on an XP machine as a art of an OS deployment with SCCM 2012 (non bootable media process). I can start the process by running the

PGPwde.exe --decrypt --passphrase ""passphrase"" --disk 0 --dedicated-mode"

works fine. what I cannot find is a way to detect when the process is done, so i can reboot. The PGPwde.exe process runs only until the actual decryption starts. is there any hidden command line to run the reboot pst decryption? Any other suggestions how to effeciently do this?

Thank you.

if you know scripting you can just run shutdown.exe /r on the next line, itll then run the shutdown.exe /r one the PGPwde.exe command has completed, i.e. when decryption is done.

I solved this with scripting ' ***************************************************************************** ' ' Decrypt a PGP drive prior of ZTI Deployment. ' We need to check the status of the decryption process before we continue ' this can be done by generating a status file and periodicall check it ' the first script starts decryption and writes teh fist status file ' this will be script # 1, ' <><><><><><><> ' // Set objFSO = CreateObject("Scripting.FileSystemObject") ' // Set wshShell = WScript.CreateObject ("WSCript.shell") ' // Set objFSO = CreateObject("Scripting.FileSystemObject") ' // Decrypt = "c:\progra~1\pgpcor~1\pgpdes~1\PGPwde.exe --decrypt --passphrase ""0611Champs"" --disk 0 --dedicated-mode" ' // Status = "CMD /c c:\progra~1\pgpcor~1\pgpdes~1\PGPwde.exe --Status>C:\status.txt" ' // wshshell.Run Decrypt,1,True ' // wshshell.Run Status,1,True ' <><><><><><> ' This is script # 2 ' Place both scripts under the Refrssh Scenario as the first group ' condition to run can bea status file or the existance of PGP folder.
