SFTP Authenticate Secure

This example requires Chilkat v9.5.0.71 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=="
// }

// These are the encryption settings we previously used to encrypt the credentials within the JSON config file.

// a randomly generated session key.)
