Filter Certificates within Existing PowerShell Query

I currently have the following PowerShell script to obtain a list of Certificates from the local certificate store:

$AllCertificates = Get-ChildItem -Path Cert:\LocalMachine\My -Recurse

# Create an empty list to keep the results

$CertificateList = @()

ForEach ( $Certificate in $AllCertificates )


    # Check to see if this is a "folder" or a "certificate"

    if ( -not ( $Certificate.PSIsContainer ) )


        # Certificates are *not* containers (folders)

        # Get the important details and add it to the $CertificateList

        $CertificateList += $Certificate | Select-Object -Property FriendlyName, Issuer, Subject, Thumbprint, NotBefore, NotAfter




Open in new window

I would like to update this so that:
  1. Only certificates that do not have the sole intended purpose of Client Authentication (So certs that have more than one purpose are always included in the final list)
  2. That the output labels for each piece of returned data is customised. For example, currently we have NotBefore which I would like to display as "Issued On"
  3. Include a comma delimited list of the Intended purposes in the final certificate list

I am somewhat of a novice with PowerShell, so any assistance would be greatly appreciated!!
