I’ve been a naysayer here, but that is mainly because I don’t think MS will create any scripting certification, not because I think it is necessarily a bad idea.

Many CAs offer different variants of code signing certificates; you need a Microsoft AuthentiCode style certificate. After you have installed a certificate, you use the Set-AuthenticodeSignature cmdlet to apply a signature to a script.

This action overrides any local setting. Thursday, December 6, 9: The script security features for Windows PowerShell are specifically designed to help prevent some of the scripting-related security problems of older technologies, including Microsoft Visual Basic Scripting Edition VBScript.

The shell has a script Execution Policy that determines what scripts are permitted to run, and by default this setting is set to Restricted, which disables script execution entirely.

And if someone did have certification in powershell, that would be a good indicator, but the area of application could be so different that an understanding of that would be much more important. The signature includes information about the certificate, including the identity of the certificate holder.

This is the default setting, and Windows PowerShell does not execute scripts, except for a few Microsoft-provided, digitally-signed scripts that contain shell configuration defaults. Not to my knowledge.

The Restricted execution policy is perfect for any computer for which you do not run scripts or for which you run scripts only rarely.
