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). React Native

import { Cert, Ftp2 } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const 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;

  const cert = new Cert();
  try {
    cert.loadPfxFile('qa_data/pfx/example.pfx', 'pfx_password');

  // Use this certificate for our TLS mutually authenticated connection:
  try {
    ftp.setSslClientCert(cert);
  } catch {
    console.log(cert.lastErrorText);

  // Establish the TLS connection with the FTP server.
