Description
When compiling a DSC configuration on Linux using Powershell 7, credentials cannot be encrypted because Protect-CmsMessage is not present on the Linux platform. This is expected since i understand it uses the CertStore #3224.
Since this is a fundamental part of a DSC Configuration is there any plan fix this or add support for encryption using a different cmdlet?
Steps to reproduce
$ConfigData = @{
AllNodes = @(
@{
NodeName = 'hostname'
CertificateFile = '/tmp/certificates/hostname.cer'
Thumbprint = '3A9016961C4650036E298DE4AA0D3BE1054B9610'
}
)
}
Configuration CredsRequired {
Import-DscResource -ModuleName PSDscResources
$myPassword = 'password' | ConvertTo-SecureString -AsPlainText -Force
$myCredential = [System.Management.Automation.PSCredential]::New('myUser', $myPassword)
Node $AllNodes.NodeName {
Group Administrators {
GroupName = 'Administrators'
MembersToInclude = 'myGroup'
Credential = $myCredential
}
}
}
& CredsRequired -ConfigurationData $ConfigDataExpected behavior
This should produce a mof file containing 'myPassword' as an encrypted blob
Actual behavior
