Signing VBScript Files with PowerShell

by Feb 19, 2014

You probably know that Set-AuthenticodeSignature can be used to digitally sign PowerShell scripts. But did you know that this cmdlet can sign anything that

This piece of code would load a digital certificate from a PFX file, then scan your home folders for VBScript files, and apply a digital signature to the scripts:

# change path to point to your PFX file:
$pfxpath = 'C:\Users\Tobias\Documents\PowerShell\testcert.pfx'
# change password to the password needed to read the PFX file:
# (this password was set when you exported the certificate to a PFX file)
$password = 'topsecret'

# load certificate
Add-Type -AssemblyName System.Security
$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
$cert.Import($pfxpath, $password, 'Exportable')

# apply signature to all VBScript files
Get-ChildItem -Path $home -Filter *.vbs -Recurse -ErrorAction SilentlyContinue |
  Set-AuthenticodeSignature -Certificate $cert -WhatIf
