(PHP ActiveX) Using WS_FTP Self-signed Certificate file (.crt) and Private Key File. (.key)

Demonstrates how to use a self-signed certificate created by WS_FTP with Chilkat FTP2.

Note: It is usually not necessary for the FTP client to use a client-side certificate. Most FTP servers using SSL and TLS connections (explicit or implicit) do not require client-side certs. In addition, some high-security FTP servers require "real" certificates -- meaning certificates issued by a real certificate authority with a chain of authentication that leads to a trusted root certificate. The certificates created by WS_FTP are self-signed and untrusted.

<?php

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

// Important:  Before running this program, convert your
// .crt and .key files to a .p12 using OpenSSL:
// The command is this:
// openssl pkcs12 -export -in test.crt -inkey test.key -out test.p12
// 

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Ftp2')
$ftp = new COM("Chilkat.Ftp2");

$ftp->Hostname = 'ftp.***.com';
$ftp->Port = 21;
$ftp->Username = 'testLogin';
$ftp->Password = 'testPassword';

// This example will use explict TLS/SSL.
// Establish an explicit secure channel after connection
// on the standard FTP port 21.
$ftp->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->Ssl = 0;

// Create an instance of a certificate store object, load a .p12 file,
// locate the certificate we need, and use it for signing.
// (a P12/PFX file may contain more than one certificate.)
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.CertStore')
$certStore = new COM("Chilkat.CertStore");
// The 1st argument is the filename, the 2nd arg is the 
// .p12 file's password.  (OpenSSL will prompty you to set a password
// when converting the .crt and .key into a .p12).
$success = $certStore->LoadPfxFile('test.p12','secret');
if ($success != 1) {
    print $certStore->LastErrorText . "\n";
    exit;
}

// cert is a Chilkat.Cert
$cert = $certStore->FindCertBySubjectCN('Your cert's common name');
if ($certStore->LastMethodSuccess == 0) {
    print $certStore->LastErrorText . "\n";
    exit;
}

$success = $ftp->SetSslClientCert($cert);

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

print 'Secure FTP Channel Established!' . "\n";
print $ftp->LastErrorText . "\n";

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

// ...
// ...

$success = $ftp->Disconnect();
