(C# UWP/WinRT) 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.
// 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"); crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex"); crypt.EncodingMode = "base64"; 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.Http http = new Chilkat.Http(); // 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.Login = ssLogin.Access(); http.SetPassword(ssPassword); // Also indicate that Basic authentication is to be used.. http.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 = await http.QuickGetStrAsync("https://www.chilkatsoft.com/helloWorld.html"); // Show the request header we sent in the QuickGetStr: Debug.WriteLine(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 |
