(C# UWP/WinRT) REST Basic Auth with Secure Strings

Demonstrates how to do REST Basic authentication using 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.

bool success;

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

// {
//   "http_login": "mCrOmA7mBA7Au9RuJGb9hw==",
//   "http_password": "jJtiI9TgErTTpqBz9JtHBw=="
// }

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.LoadFile("qa_data/passwords/http.json");

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

// 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");

Chilkat.SecureString ssLogin = new Chilkat.SecureString();
Chilkat.SecureString 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("http_login"),ssLogin);
crypt.DecryptSecureENC(json.StringOf("http_password"),ssPassword);

Chilkat.Rest rest = new Chilkat.Rest();

// Connect to a REST server.
bool bTls = true;
int port = 443;
bool bAutoReconnect = true;
success = await rest.ConnectAsync("chilkatsoft.com",port,bTls,bAutoReconnect);

// Cause the "Authorization: Basic ..." header to be added to HTTP requests
rest.SetAuthBasicSecure(ssLogin,ssPassword);

string responseJson = await rest.FullRequestNoBodyAsync("GET","/helloWorld.html");
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;

// Show the LastRequestHeader that was sent.
Debug.WriteLine(rest.LastRequestHeader);

// The LastRequestHeader looks like this:
