ConvertTo-SecureString Error

Question

_{Monday, August 13, 2012 12:02 PM}

Hello,

I get an error at PS script position convertTo-SecureString. The PS script is starting from a batchfile. The Batchfile is starting from a webservice!

# Import PSW:$textFromFile = Get-Content "\\zserver\c$\temp\encrypted_ysastagmespre.txt"$secpasswd = ConvertTO-SecureString $textFromFile

Error message at $secpasswd:

ConvertTo-SecureString : Key not valid for use in specified state.
At C:\Program Files\BuildPackage\IISClickOncePrepareDeploy.ps1:785 char:105
+         $secpasswd = Get-Content "\zserver\c$\temp\encrypted_ysastagmes
pre.txt" | ConvertTO-SecureString <<<<
    + CategoryInfo          : InvalidArgument: (:) [ConvertTo-SecureString], C
   ryptographicException
    + FullyQualifiedErrorId : ImportSecureString_InvalidArgument_Cryptographic
   Error,Microsoft.PowerShell.Commands.ConvertToSecureStringCommand

I hope somebody can help me,

Thanks Horst MOSS 2007 Farm; MOSS 2010 Farm; TFS 2010; IIS 7.5

Try:

$secpasswd = ConvertTO-SecureString $textFromFile -asplaintext -Force

Hello,

In another scipt I have done this, to generate the file with key password:

$secpasswd = ConvertTo-SecureString -String "Pass$$word" -AsPlainText -ForceConvertFrom-SecureString -SecureString $secpasswd | out-file "\\zserver\c$\temp\encrypted_ysastagmespre.txt

In the script, where i start a porcess with the username and password, looks like this:

$textFromFile = Get-Content "\\zserver\c$\temp\encrypted_ysastagmespre.txt"$secpasswd = ConvertTO-SecureString $textFromFile$svcCredentials = New-Object System.Management.Automation.PSCredential("domian\username", $secpasswd)$Params = "-Sign", `    "`"C:\Temp\Client.Shell.application`"", `   "-Certfile", "`"C:\Temp\TemporaryKey.pfx`""   Start-Process "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\NETFX 4.0 Tools\mage.exe" -ArgumentList $Params -LoadUserProfile -Credential $svcCredentials -Wait # -WindowStyle Hidden; $?

I am not a powershell expert, sorry about this,

Thanks,
