Dart Requires Chilkat v11.0.0+

SFTP use Cert's Private Key for Authentication (Windows)

See more SFTP Examples

Demonstrates how to use the private key of a pre-installed certificate (on Windows) for SFTP authentication. The certificate's private key must be marked as "exportable" when originally installed. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final cert = CkCert();

  // Load the certificate from the Windows certificate store
  try {
    cert.loadByCommonName('my_cert_common_name');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Get the private key.  
  final privKey = CkPrivateKey();
  try {
    cert.getPrivateKey(privKey);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final String privKeyPem;
  try {
    privKeyPem = privKey.getPkcs8Pem();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;

  final sshKey = CkSshKey();
  try {
    sshKey.fromOpenSshPrivateKey(privKeyPem);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Connect to an SSH/SFTP server
  final sftp = CkSFtp();
  try {
    sftp.connect('sftp.example.com', 22);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Authenticate with the SSH server using a username + private key.
  // (The private key serves as the password.  The username identifies
  // the SSH user account on the server.)
  try {
    sftp.authenticatePk('mySshLogin', sshKey);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('OK, the connection and authentication with the SSH server is completed.');

  // This example is only to show the connection + authentication using a private key associated with a certificate in the Windows certificate store...
