(Android™) HTTP Basic Auth with Secure StringsDemonstrates how to do HTTP basic authentication using secure strings. This example requires Chilkat v9.5.0.71 or greater.
// Important: Don't forget to include the call to System.loadLibrary // as shown at the bottom of this code sample. package com.test; import android.app.Activity; import com.chilkatsoft.*; import android.widget.TextView; import android.os.Bundle; public class SimpleActivity extends Activity { private static final String TAG = "Chilkat"; // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. boolean 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==" // } CkJsonObject json = new CkJsonObject(); json.LoadFile("qa_data/passwords/http.json"); CkCrypt2 crypt = new CkCrypt2(); // These are the encryption settings we previously used to encrypt the credentials within the JSON config file. crypt.put_CryptAlgorithm("aes"); crypt.put_CipherMode("cbc"); crypt.put_KeyLength(128); crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex"); crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex"); crypt.put_EncodingMode("base64"); CkSecureString ssLogin = new CkSecureString(); CkSecureString 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("http_login"),ssLogin); crypt.DecryptSecureENC(json.stringOf("http_password"),ssPassword); CkHttp http = new CkHttp(); // Cause the "Authorization: Basic ..." header to be added to HTTP requests // by setting the Login and Password properties. However, instead of setting the password property // directly, set it via the SetPassword method using the secure string. http.put_Login(ssLogin.access()); http.SetPassword(ssPassword); // Also indicate that Basic authentication is to be used.. http.put_BasicAuth(true); // Do an HTTP GET w/ Basic authentication. // REMEMBER: Always use TLS with Basic authentication. Otherwise your credentials are exposed for the world to see.. String responseStr = http.quickGetStr("https://www.chilkatsoft.com/helloWorld.html"); // Show the request header we sent in the QuickGetStr: Log.i(TAG, http.lastHeader()); // The LastHeader looks something like this: // GET /helloWorld.html HTTP/1.1 // Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 // Connection: keep-alive // User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0 // Accept-Language: en-us,en;q=0.5 // Authorization: Basic bXlIdHRwTG9naW46bXlIdHRwUGFzc3dvcmQ= // Accept-Encoding: gzip // Host: www.chilkatsoft.com } static { System.loadLibrary("chilkat"); // Note: If the incorrect library name is passed to System.loadLibrary, // then you will see the following error message at application startup: //"The application <your-application-name> has stopped unexpectedly.
