Set an FTPS Client Certificate from a PFX File

See more FTP Examples

Demonstrates the Chilkat Ftp2.SetSslClientCertPfx method, which loads a client certificate and private key from a PFX/P12 file. The first argument is the file path and the second is its password.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

import 'package:chilkat/chilkat.dart';

void main() {
  // Demonstrates the Ftp2.SetSslClientCertPfx method, which loads a client certificate and private
  // key from a PFX/P12 file.  The 1st argument is the PFX file path and the 2nd is its password.

  final ftp = CkFtp2();

  ftp.hostname = 'ftp.example.com';
  ftp.username = 'myFtpLogin';

  // Normally you would not hard-code the password in source.  You should instead obtain it
  // from an interactive prompt, environment variable, or a secrets vault.
  ftp.password = 'myPassword';

  // Use explicit FTPS (AUTH TLS) on the standard FTP port.
  ftp.authTls = true;

  // Provide the PFX client certificate before connecting.  The password should come from a secure
  // source rather than being hard-coded.
  final pfxPassword = 'myPfxPassword';
  try {
    ftp.setSslClientCertPfx('qa_data/client.pfx', pfxPassword);
