Using PowerShell to check a websites SSL Certificate

This powershell function will grab the SSL certificate from a website, make the name, issuer and ExpirationDate a little more accessible and return it.

[code]

function Get-WebCertificate (){
    [cmdletbinding()]
    param(
        [parameter(ValueFromPipelineByPropertyName,ValueFromPipeline)]
        [string]$Name
    )
    process {
        if ($Name -notlike 'https://*') {
            $Name = "https://$Name"
        }
        Write-Host $Name
        [Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
        $req = [Net.HttpWebRequest]::Create($Name)
        if ($req) {
            $req.Timeout = 5000
            try {$req.GetResponse()} catch {}
            $certificate = $req.ServicePoint.Certificate
        }
        if ($certificate) {            
            $certificate | %{ New-Object -TypeName PSObject -Prop @{'Name'=$Name; 'Issuer'=$certificate.Issuer; 'ExpirationDate'=$certificate.GetExpirationDateString(); 'Subject'=$certificate.Subject }   }
        }
    }
}
