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). PHP Extension

<?php

$success = false;

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

$ftp->put_Port(21);

// If using implicit TLS, you probably want port 990..
$ftp->put_Port(990);

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

// Set this to true for implicit TLS, otherwise set to false.
