PowerShell Script - Website Certificate Information

It is difficult to manage the certificates for websites. When websites hosted on server are large in number task become more tedious and complicated. We have also received similar task for collecting  details of certificates for each website on remote server. In our case websites hosted on server were large in number and manually collecting the details for the certificates was time consuming task. So we came up with below PowerShell script which will help us to provide the details.

Script  

Import-Module -Name WebAdministration


Get-ChildItem -Path IIS:SSLBindings | ForEach-Object -Process `
{
    if ($_.Sites)
    {
        $certificate = Get-ChildItem -Path CERT:LocalMachine/My | Where-Object -Property Thumbprint -EQ -Value $_.Thumbprint       

        [PsCustomObject]@{
            Sites                        = $_.Sites.Value
            CertificateFriendlyName      = $certificate.FriendlyName                     
            CertificateIssuer            = $certificate.Issuer
            ExpiryDate                   = [string]$certificate.NotAfter            
        }
    }
} | ConvertTo-Json  | Out-File -Width 4096 C:\ServerCertDetails.json -Append 

Above script will provide details of fields for each website hosted on server.

• Website Name
• Certificate Name
• Certificate Issuer
• Certificate Expiry Date

You can customize display details as per your requirement. It will convert the details into json file and save it in specified location.
