PowerShell Requires Chilkat v10.1.2+

Secure FTP with Client Certificate

See more FTP Examples

Chilkat FTP2 provides the ability to use a client certificate with secure FTP (implicit or explicit SSL/TLS). This example demonstrates how to load a certificate from a .pfx and use it as the client-side SSL cert. Note: Client-side certificates are only needed in situations where the server demands one.

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

$ftp = New-Object Chilkat.Ftp2

$ftp.Hostname = "ftp.example.com"

#  This example will use explict TLS/SSL.
#  Establish an explicit secure channel after connection
#  on the standard FTP port 21.
$ftp.AuthTls = $true

#  The Ssl property is for establishing an implicit SSL connection
#  on port 990.  Because this example uses explicit SSL, it 
#  should remain $false.
