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

$success = $false

#  This example assumes Chilkat Ftp2 to have been previously unlocked.
#  See Unlock Ftp2 for sample code.

$ftp = New-Object Chilkat.Ftp2

$ftp.Hostname = "www.authtls-ftps-server.com"
$ftp.Username = "FTP_LOGIN"
$ftp.Password = "FTP_PASSWORD"
$ftp.AuthTls = $true
$ftp.Port = 21

#  Connect to the FTP server using explicit TLS (AUTH TLS).
$success = $ftp.ConnectOnly()
if ($success -eq $false) {
    $($ftp.LastErrorText)
    exit
}

#  Get the FTP server's certificate.
$serverCert = New-Object Chilkat.Cert
$success = $ftp.GetServerCert($serverCert)
if ($success -eq $false) {
    $($ftp.LastErrorText)
    exit
}

#  Now that we have the certificate, we can check it in any way we desire.
#  (See the online reference documentation for the certificate object's methods
#  and properties)...

#  Assuming the certificate is OK, proceed to authenticate with the FTP server.
$success = $ftp.LoginAfterConnectOnly()
if ($success -eq $false) {
    $($ftp.LastErrorText)
    exit
}

#  Proceed with uploading/download files, etc...

$ftp.Disconnect()
$("Success.")
