Powershell list certificates

Nevermind - I figured out it was an indexed array.

for($i=0; $i -lt $certs.count; $i++) { 
    $certdate = $certs[$i].certificate.expiration_string; 
    $certcn = $certs[$i].certificate.subject.common_name; 
    write-host "Common Name is $certcn" 
    write-host "Expiration date is $certdate" 
}
