(JavaScript) SFTP Authenticate Secure

Demonstrates how to do SFTP password authentication with secure strings.

This example requires Chilkat v9.5.0.71 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

// Imagine we've previously saved our encrypted login and password within a JSON config file
// that contains this:

// {
//   "ssh_login": "2+qylFfC56Ck7OQQt/U2/w==",
//   "ssh_password": "5neIq9Jmn0E3p71N6Yc8TA=="
// }

var json = new CkJsonObject();
json.LoadFile("qa_data/passwords/ssh.json");

var crypt = new CkCrypt2();

// These are the encryption settings we previously used to encrypt the credentials within the JSON config file.
crypt.CryptAlgorithm = "aes";
crypt.CipherMode = "cbc";
crypt.KeyLength = 128;
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex");
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex");
crypt.EncodingMode = "base64";

var ssLogin = new CkSecureString();
var ssPassword = new CkSecureString();

// Decrypt to the secure string.  (the strings will still held in memory encrypted, but are now encrypted using
// a randomly generated session key.)
crypt.DecryptSecureENC(json.StringOf("ssh_login"),ssLogin);
crypt.DecryptSecureENC(json.StringOf("ssh_password"),ssPassword);

var sftp = new CkSFtp();

success = sftp.Connect("MY-SSH-SERVER-DOMAIN-OR-IP",22);
if (success !== true) {
    console.log(sftp.LastErrorText);
    return;
}

// Authenticate using secure strings
success = sftp.AuthenticateSecPw(ssLogin,ssPassword);
if (success !== true) {
    console.log(sftp.LastErrorText);
    return;
}

console.log("SFTP Authentication successful.");

sftp.Disconnect();
