Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

#  This example assumes the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

$socket = New-Object Chilkat.Socket

#  Connect to a server.
$useTls = $true
$maxWaitMs = 2000
$success = $socket.Connect("www.intel.com",443,$useTls,$maxWaitMs)
if ($success -eq $false) {
    $($socket.LastErrorText)
    exit
}

#  If we get here, the TLS connection ws made..
#  In any SSL/TLS handshake, the server sends its certificate in a TLS handshake message.
#  Chilkat will keep it cached within the object that made the connection.
#  Get the server's cert and examine a few things.
$cert = New-Object Chilkat.Cert
$socket.GetServerCert($cert)
