powershell - How can I delete certificate that has specific template?

Question

I have some certificates on Windows. These certs has different templates.

I can get thumbprints:

$Certificates = get-childitem cert:LocalMachineMy

I can get templates:

$Template = ($Certificates.extensions | where-object{$_.oid.FriendlyName -match "Certificate Template Information"}).format(0)

So I want to automate deleting cert that has specific template according to thumbprint with powershell.

Answer 1

Wrap it in a Where-Object filter:

Get-ChildItem cert:my |Where-Object{
  ($TmplExt = $_.Extensions |Where-Object {
    $_.Oid.FriendlyName -match 'Certificate Template'
  }) -and 
  $TmplExt.format(0) -match 'MyTemplateName'
} |Remove-Item
