Is there any way to secure the arguments string inside the package resource?

Spent the day configuring the cert setup for using PsDscRunAsCredential and then.. oh yeah, the credentials are also in the Arguments string 🙁

I'm not certain I follow... "also in the Arguments string?" "Inside the package resource?"

Unfortunately I have something like this. I can encrypt the PsDscRunAsCredential but I also have to use this string in the arguments.

$commandargs = @" 

$credentials = New-Object System.Management.Automation.PSCredential($SMSQLUSER,$SMSQLPASS)

WindowsFeature Netframework
Ensure = "Present"
Name = "NET-Framework-Core"

Package SnapInstall 
    Ensure = "Present" 
    Path = "c:\windows\temp\SnapDrive7.1.4P1_x64.exe" 
    Name = "SnapDrive" 
    ProductId = "{0BD0F422-C9DF-4438-ABCE-74805CC8C2F5}" 
    Arguments = $commandargs
    PsDscRunAsCredential = $credentials
    DependsOn = '[WindowsFeature]Netframework'

Oh. So you're generally asking, "how can I protect sensitive information in an argument" regardless of whether it's a credential per se.

That was more or less asked at also.

Also at, which gives us a clue: you can't. The intent would be to have that data live in some kind of key vault, and you'd retrieve it dynamically somehow.

Thanks. I hope encrypting the entire mof is planned for the future.
