FTPS with Mutual TLS Authentication (TLS Client Certificate)

See more FTP Examples

Demonstrates how to do mutual TLS authentication (using a client certificate from a .pfx/.p12). Chilkat2 PHP

<?php

use Chilkat2\Cert;
use Chilkat2\Ftp2;

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

$ftp = new Ftp2();

$ftp->Hostname = 'ftp.example.com';
$ftp->Port = 21;

// If using implicit TLS, you probably want port 990..
$ftp->Port = 990;

// Set this to false for implicit TLS, otherwise set to true for explicit TLS (where port is typically 21).
$ftp->AuthTls = false;

// Set this to true for implicit TLS, otherwise set to false.
$ftp->Ssl = true;

$cert = new Cert();
try {
    $cert->LoadPfxFile('qa_data/pfx/example.pfx', 'pfx_password');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Use this certificate for our TLS mutually authenticated connection:
try {
    $ftp->SetSslClientCert($cert);
} catch (\Chilkat2\Exception $e) {
    echo $cert->LastErrorText, "\n";
    exit;
}

// Establish the TLS connection with the FTP server.
try {
    $ftp->ConnectOnly();

    // If a login is required, then login with the FTP account login/password.
    $ftp->Username = 'myLogin';
    $ftp->Password = 'myPassword';
    $ftp->LoginAfterConnectOnly();
} catch (\Chilkat2\Exception $e) {

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