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" 
}

Hi , 
i wrote something with powershell that can be use.
the script export the SSL certificates - calculate the expiration date 60 days back and send the report in table to email (if you have mail relay)
the script : 
Add-PSSnapin iControlSnapIn
$f5_VA_1= "big_ip_address_no1"
$f5_va_3 = "big_ip_address_no2"
$f5_ams_1 = "big_ip_address_no3"
$f5_all = @("$f5_VA_1","$f5_va_3","$f5_ams_1")
$table = $null
$row = $null

 Create the Report Table

 Table

$tabName = "Table"

 Create Table object

$table = New-Object system.Data.DataTable &8220;$tabName&8221;

 Define Columns

$ColumnName1="F5_Name"
$ColumnName2="Object"
$ColumnName3="Status"
$ColumnName4="Action"

 $ColumnName5="Error"

$col1 = New-Object system.Data.DataColumn $ColumnName1,([string])
$col2 = New-Object system.Data.DataColumn $ColumnName2,([string])
$col3 = New-Object system.Data.DataColumn $ColumnName3,([string])
$col4 = New-Object system.Data.DataColumn $ColumnName4,([string])

 $col5 = New-Object system.Data.DataColumn $ColumnName5,([string])

 Add the Columns

$table.columns.add($col1)
$table.columns.add($col2)
$table.columns.add($col3)
$table.columns.add($col4)

 $table.columns.add($col5)

$row = $null

 Create a row

        $row = $table.NewRow()
        Enter data in the row
        $row.$ColumnName1 = "$f5"
        $row.$ColumnName2 = "$certcn"
        $row.$ColumnName3 = "$certdate"
        $row.$ColumnName4 = "Please Check the Certificate Status"
        Add Row to Table
        $table.Rows.Add($row)
        $certcn = $null
    `</pre>

    foreach ($f5 in $f5_all){

    <pre class="prettyprint lang-tcl">`Initialize-F5.iControl -Hostname $f5 -username admin -Password Big-IP_password

    $begin = Get-Date -UFormat &quot;%m/%d/%Y&quot;
    `</pre>

    $now = (get-date).AddDays(-60)
    $g_ic = Get-F5.iControl
    $ErrorActionPreference = &quot;silentlycontinue&quot;
    $certs = ($g_ic).ManagementKeyCertificate.get_certificate_list('0');
        for($i=0; $i -le $certs.count; $i++) {
            $certdate = $certs[$i].certificate.expiration_string; 
            $certcn = $certs[$i].certificate.subject.common_name;

    <pre class="prettyprint lang-tcl">`    $certdate1 = ($certdate -split ' ')[0,1,3] 
    `</pre>

    $certdate2 = $certdate1[0] +&quot; &quot; + $certdate1[1] +&quot; &quot; + $certdate1[2]
       $certdate3 = [datetime]::ParseExact($certdate2,&quot;MMM dd yyyy&quot;,$null)
       $monthdiff = ($certdate3 - [datetime]$begin).TotalDays 

    <pre class="prettyprint lang-tcl">` Get certificates from all F5 
       if($monthdiff -le 60 -and $certcn -ne $null){
        $row = $table.NewRow()
        Enter data in the row
        $row.$ColumnName1 = $f5
        $row.$ColumnName2 = &quot;$certcn&quot;
        $row.$ColumnName3 = &quot;$certdate3&quot;
        $row.$ColumnName4 = &quot;the certificate $certcn will expire in $monthdiff days&quot;
        Add Row to Table
        $table.Rows.Add($row)
       }
    }

}
$table

 Send Report if Error exist

if ($table -ne $null){

$Header=$null
    $Header = @&quot;
&lt;style&gt;
TABLE {border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}
TH {border-width: 1px;padding: 3px;border-style: solid;border-color: black;background-color: 6495ED;}
TD {border-width: 1px;padding: 3px;border-style: solid;border-color: black;}
&lt;/style&gt;
&quot;@

$bodytable = $table | select $ColumnName1,$ColumnName2,$ColumnName3,$ColumnName4 | ConvertTo-Html -Head $Header  -PreContent $Pre -PostContent $Post

 only if you have mail relay

$mailto=&quot;mail_address&quot;
$mailfrom=&quot;from where you get mail&quot;
$smtp=&quot;mail_relay_ip&quot;

Send-MailMessage -To &quot;mailto&quot; -Subject &quot;certificates&quot; -Body &quot;$bodytable&quot;` -BodyAsHTML -SmtpServer $smtp -From $mailfrom
