Perl 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. Perl

use chilkat();

$success = 0;

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

$ftp = chilkat::CkFtp2->new();

$ftp->put_Hostname("ftp.example.com");
$ftp->put_Port(21);
$ftp->put_Username("test");
$ftp->put_Password("test");

#  This example will use explict TLS/SSL.
#  Establish an explicit secure channel after connection
#  on the standard FTP port 21.
$ftp->put_AuthTls(1);

#  The Ssl property is for establishing an implicit SSL connection
#  on port 990.  Because this example uses explicit SSL, it 
#  should remain 0.
$ftp->put_Ssl(0);

#  Load a certificate from a .pfx
#  A PFX may contain several certs, including the certificates
#  in a chain of authority.
$certStore = chilkat::CkCertStore->new();

$password = "***";
#  Load the certs from a PFX into an in-memory certificate store:
$success = $certStore->LoadPfxFile("chilkat.pfx",$password);
if ($success != 1) {
    print $certStore->lastErrorText() . "\r\n";
    exit;
}

#  Find the desired certificate.
$jsonCN = chilkat::CkJsonObject->new();
$jsonCN->UpdateString("CN","cert common name");

$cert = chilkat::CkCert->new();
$success = $certStore->FindCert($jsonCN,$cert);
if ($success == 0) {
    print "Certificate not found!" . "\r\n";
    exit;
}

#  Use this certificate for our secure (SSL/TLS) connection:
$success = $ftp->SetSslClientCert($cert);

#  Connect and login to the FTP server.  The connection is 
#  made secure because of the AuthTls setting.
$success = $ftp->Connect();
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}
else {
    #  LastErrorText contains information even when
    #  successful. This allows you to visually verify
    #  that the secure connection actually occurred.
    print $ftp->lastErrorText() . "\r\n";
}

print "Secure FTP Channel Established!" . "\r\n";

#  Do whatever you're doing to do ...
#  upload files, download files, etc...

#  .....
#  .....

$success = $ftp->Disconnect();
