React Native 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. React Native

import { Cert, PrivateKey, SFtp, SshKey } from '@chilkat/react-native'

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

  const cert = new Cert();

  // Load the certificate from the Windows certificate store
  try {
    cert.loadByCommonName('my_cert_common_name');
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  // Get the private key.  
  const privKey = new PrivateKey();
  try {
    cert.getPrivateKey(privKey);
  } catch {
    console.log(cert.lastErrorText);
    return;

  try {
    privKeyPem = privKey.getPkcs8Pem();
  } catch {
    console.log(privKey.lastErrorText);

  const sshKey = new SshKey();
  try {
    sshKey.fromOpenSshPrivateKey(privKeyPem);
  } catch {
    console.log(sshKey.lastErrorText);
    return;
  }

  // Connect to an SSH/SFTP server
  const sftp = new SFtp();
  try {
    await sftp.connectAsync('sftp.example.com', 22);
  } catch {
    console.log(sftp.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 {
    await sftp.authenticatePkAsync('mySshLogin', sshKey);
  } catch {
    console.log(sftp.lastErrorText);
    return;
  }

  console.log('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...
