SecureKey Code Examples

The topic is provided to help developers who are writing applications that will call a Logi application using Logi SecureKey Authentication. Language examples include:

General Information

Logi SecureKey Authentication is a technology we offer for use in "single sign-on" scenarios, where a non-Logi application (the "Parent" application), which conducts the initial user authentication, is integrated with a Logi application. SecureKey Authentication provides a method of securely accessing the integrated Logi app, and is discussed in detail in Use Logi SecureKey Authentication.

This topic provides examples of the Parent application code required to establish the flow of secure exchanges with a Logi application using SecureKey.

The examples, in several languages, are very generic and are only intended to provide the basic, necessary code. They're provided with the assumption that developers who undertake using them and extending their functionality have in-depth skills with the language selected. Other languages can also be used and success with them will, again, depend on the developer's skills.

C# (.NET)

The following code example is written in C#, for use with the .NET framework:

  1. /* set up the SecureKey call */
  2. // define parts of the SecureKey request URL
  3. string strLogiAppBaseURL = "http://<yourServer>/<LogiApp>";
  4. string UserName = "Bob";
  5. string Roles = "Admin";
  6. string Rights = "Manager";
  7. string ClientBrowserAddress = Request.ServerVariables["REMOTE_ADDR"];
  8.  
  9. // build complete URL to Logi app
  10. string sGetKeyURl = "/rdTemplate/rdGetSecureKey.aspx?Username=" + UserName + "&Rights=" + Rights  + "&Roles=" +  Roles + "&ClientBrowserAddress=" + ClientBrowserAddress;
  11. string sFinalURL = strLogiAppBaseURL + sGetKeyURl;
  12.  
  13. // create and send SecureKey request
  14. string sKey = "";
  15. HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.Create(sFinalURL);
  16. HttpWebResponse webResponse;
  17.  
  18. // attempt to make SecureKey call, read return into sKey
  19. try
  20. {
  21.    webResponse = (HttpWebResponse)webRequest.GetResponse();
  22.    Stream myStream;
  23.    myStream = webResponse.GetResponseStream();
  24.    StreamReader sr = new StreamReader(myStream);
  25.    sKey = sr.ReadToEnd();
  26. }
  27. catch (Exception ex) // if not bad URL, send error message
  28. {
  29.    if (ex.Message.IndexOf("401") != -1)
  30.    {
  31.       Response.Write("Not Found");
  32.    }
  33.    else
  34.    {
  35.       Response.Write(ex.Message.ToString());
  36.    }
  37. }

Visual Basic (.NET)

The following code example is written in Visual Basic, for use with the .NET framework:

  1. ' set up the SecureKey call
  2. ' define parts of the SecureKey request URL
  3. Dim strLogiAppBaseURL As String = "http://<yourServer>/<LogiApp>"
  4. Dim strUserName = "Bob"
  5. Dim strUserRoles = "Admin"
  6. Dim strUserRights = "Manager"
  7. Dim strClientBrowserAddr As String = Request.UserHostAddress
  8.  
  9. ' build complete URL to Logi app
  10. Dim strGetKeyURL As String = "/rdTemplate/rdGetSecureKey.aspx?Username=" & strUserName & "&Roles=" & strUserRoles & "&Rights=" & strUserRights & "&ClientBrowserAddress=" & strClientBrowserAddr
  11. Dim sFinalURL As String = strLogiAppBaseURL & strGetKeyURL
  12.  
  13. ' define web request and response receiver
  14. Dim webRequest As Net.HttpWebRequest
  15. Dim webResponse As Net.WebResponse|
  16. webRequest = Net.HttpWebRequest.Create(strFinalURL)
  17.  
  18. ' attempt to make SecureKey call
  19. Try
  20.    webResponse = webRequest.GetResponse()
  21. Catch ex As Exception
  22.    ' if server has Basic or NTLM authentication, try to set credentials from the current process
  23.    If ex.Message.IndexOf("401") <> -1 Then
  24.       webRequest.Credentials = Net.CredentialCache.DefaultCredentials
  25.       webResponse = webRequest.GetResponse()
  26.    Else
  27.       Throw ex
  28.    End If
  29. End Try
  30.  
  31. ' receive the response and return it as function result
  32. Dim sr As New IO.StreamReader(webResponse.GetResponseStream())
  33. getSecureKey = sr.ReadToEnd()

  42.    LogiAppURL = LogiAppURL + "/rdPage.aspx?rdSecureKey=" + sb.toString();  
  43.             
  44.    // redirect to the application with SecureKey parameter
  45.    response.sendRedirect(LogiAppURL);
  46. }
