Demonstrates how to do SSH password authentication with secure strings.

This example requires Chilkat v9.5.0.71 or greater.

    //  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 ssLogin = new chilkat.SecureString();
    var ssPassword = new chilkat.SecureString();

    //  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 ssh = new chilkat.Ssh();
