Converting the Windows Script Host SignFile Method

Windows PowerShell

Definition: Signs a script using a digital signature.


Assuming you have a certificate that can be used for code signing, Windows PowerShell makes it easy to attach a digital signature to a script. All you have to do is bind to the certificate, then use the Set-AuthenticodeSignature cmdlet to sign the script. For example, in the following block of code the Get-ChildItem cmdlet is used to retrieve a user certificate with the friendly name Script Signer. After the certificate has been retrieved, Set-AuthenticodeSignature then digitally signs the file C:\Scripts\Test.ps1:

$objCertificate = Get-ChildItem Cert:\CurrentUser\My | Where-Object {$_.FriendlyName -eq "Script Signer"}
Set-AuthenticodeSignature C:\Scripts\Test.ps1 -certificate $objCertificate

If you don’t have a certificate that can be used for code-signing you can always create your own by downloading MakeCert.exe. For more information, see the MakeCert home page.
