Security :: RSA Key Container Couldn't Be Opened / Found
Jan 25, 2010
When trying to open a page I am getting this error: Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened. I did some reading and it seems that this command woudl fix it:
from here [URL]
aspnet_regiis -pa "NetFrameworkConfigurationKey" "ASPNET"
I tried that but I get a new error:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727>aspnet_regiis -pa "NetFrameworkCon
figurationKey" "ASPNET"
Adding ACL for access to the RSA Key container. The RSA key container was not found. failed . Now, I don't really understand all of this stuff (my boss just said: Heres the problem, fix it).

I am trying to debug on my local machine an application that has encrypted connection strings. The error when I go to register the Key Container is:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727>aspnet_regiis -pa "CompanyDirector
yKeyContainer" "PHXDEVELOPER26ASPNET"
Adding ACL for access to the RSA Key container. The RSA key container was not found. Failed! I am getting this when I run the debug:

And, last but not least, I did copy all the MachineKeys over into my MachineKey directory as well, with one explicitly saying CompanyDirectoryKeyProvider in it. What I am doing wrong and what do I need to do to correct this?

I am trying to copy a website from one server to another, however I am getting the error above
<connectionStrings configProtectionProvider="WSConfigProvider">
Line 51: <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"

Line 53: <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#tripledes-cbc" />
I have copied the entire site so cant think what file it could be missing, however looking at the article [URL] .... I cannot seem to find the location Documents and Settings{UserName}Application DataMicrosoftCryptoRSA on the server, where would this be on a 2008r2 server? And is there some files in there missing which could be causing this error?

I had a working vs2008 web project that I needed to convert to a web application. After copying all my pages and user code into my new web solution, I am unable to compile the solution because it is not detecting the original namespace (Lead) that I was using in the web project (see error below). Error 9 The type or namespace name 'Lead' could not be found (are you missing a using directive or an assembly reference?) C:Documents and SettingsasnakbeMy DocumentsVisual Studio 2008ProjectsSLMSSLMSleads.aspx.cs 12 5 SLMS
I even tried changing the namespace to a different one, did clean/build the project, etc. but that all didn't help. Can someone let me know what I could be missing here?

We use HttpContext.Current.User.Identity.Name to resolve the name of the currently loggen in user in the intranet sites we develop. Normally this works adequately, but we've recently encountered problems when installing an intranet on an IIS7.5 Server. The weird thing is that ASP.NET throws an error when executing an extremely simple page for debugging purposes:
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
</script>
<html xmlns="[URL]/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<%= HttpContext.Current.User.Identity.Name %>
</div>
</form>
</body>
</html>
The error is:
[Code]....
[IdentityNotMappedException: Some or all identity references could not be translated.] System.Security.Principal.SecurityIdentifier.Translate(IdentityReferenceCollection sourceSids, Type targetType, Boolean forceSuccess) +309 System.Security.Principal.SecurityIdentifier.Translate(Type targetType) +125 System.Security.Principal.WindowsIdentity.GetName() +154 System.Security.Principal.WindowsIdentity.get_Name() +42 ASP.test_default_aspx.__Renderform1(HtmlTextWriter __w, Control parameterContainer) in c:inetpubwebsitewwwroot extranet estdefault.aspx:16 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +115 System.Web.UI.HtmlControls.HtmlForm.RenderChildren(HtmlTextWriter writer) +253 System.Web.UI.HtmlControls.HtmlForm.Render(HtmlTextWriter output) +87 System.Web.UI.HtmlControls.HtmlForm.RenderControl(HtmlTextWriter writer) +53 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +240 System.Web.UI.Page.Render(HtmlTextWriter writer) +38 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +4240
The beauty of it all is that an old school, classic ASP page that basically does the same thing doesn't throw an error, but just does what it has to do:
<%
response.write "Remote User: " & Request.ServerVariables("REMOTE_USER")
%>
This code simply delivers the name of the remote user. But the ASP.Net version doesn't deliver. The same server, same directory, same user. Different ASP version. Does anyone have an idea?

My web.comfig file in the webserver is encrypted . I want to do a change to the config file. While I'm trying to decrypt from the command prompt on the server using following command. "aspnet_regiis -pd "appSettings" -app "/AppName" I endup with the following error message. Failed to decrypt using provider 'CustomProvider'. Error message from the provider: The RSA key container could not be opened. The RSA key container could not be opened. Failed! The same command has been working in other environments except in my servers. Also I'm using web forms and I tried the same in both the servers. I have gone through all websites but no use.

1) I want to create a rsa key in c# and export the container. I am having difficulty. I create container like this:
[Code]....
The msdn example says I can export the container with this syntax: aspnet_regiis -pa "XML_ENC_RSA_KEY" "NT AUTHORITYNETWORK SERVICE". This does not work on my XP Host PC. I belive this is applicable for Windows 2003 Server. So what is the correct syntax for exporting rsa key container from XP host?
2) To get aspnet_regiis.exe path I did something like this:
[Code]....
But this path may be different for each host, based on the .NET verison installation. Is there a way to get the aspnet_regiis.exe path from registry or a environment varaible?
3) Once I get the path to aspnet_regiis.exe I want to invokve it from c# like this.Is this code correct?
[Code]....

We recently retired our server 2003 domain controllers and moved to server 2008r2 DCs. We overlooked an old web application built using asp.net. The error we receive when attempting to log into the app is below. I assumed a setting in the web.config was pointed at a retired DC and it was. Removed the old value and added the correct DC name and we are still generating the error.

My application source code is under Driver H: in my Dev server.
The security settings under Driver C: (right click->properties->security tab) has access setup as "Everyone", but when I remove "Everyone" from C: and run my application, I am getting HTTP 404 - File not found. The app works fine if it has Everyone. I dont want to grant access to Everyone under C:.
How can I run my app which is setup under driver H: run without any issues by removing the Everyone Access in C drive.

This is probably a lame question, but I know little of web development. I inherited a web project that I'm trying to get running locally. I get the mentioned error on line 46.
Line 44: </authentication>
Line 45: <membership defaultProvider="AD_MyCompanyName" />
Line 46: <roleManager enabled="true" defaultProvider="ADRP_MyCompanyName_Readonly" cacheRolesInCookie="true" cookieName="MyCompanyName.ROLES" createPersistentCookie="true" cookieSlidingExpiration="true" cookieTimeout="240" />
Line 47: <profile enabled="false"/>
Line 48: <customErrors mode="Off"/>
This code works on the old developer's box, but not on mine. I've been working through some TFS checkout issues on his box, assuming it was simply files left checked out. I can't figure out where the providers are added. I don't see them being added in the config file above. In fact, if I search for "AD_MyCompanyName" and "ADRP_MyCompanyName_Readonly", I get no hits in the entire solution. I can't figure out what they are. Not sure why it works on that box if I can't even find the providers being added.

I am building an excel file using the OpenXml sdk 2.0. I am putting it in a memory stream and outputting it to the browser.The problem I am receiving is wiht IE 9 if I click Open it says "filename couldn't be downloaded". If I hit save/save as and save it to the filesystem, then open it, the file opens fine with no errors.
In Firefox regardless of if I use save or open the file when opened in excel says its corrupt.I already built the file by writing it to the filesystem first and that code works. Also since saving to desktop in IE lets me open the file, im assuming the problem has to be with the settings on the Response.BinaryWrite.
I have tried changing the buffer types, changing the content types to include "application/octet-stream", and tried using the extension/content type for office 2003 instead of 2007/2010...Here is my code
Code:
Dim byteArray As Byte()
Using mStream As New MemoryStream
Using spreadSheetDoc As SpreadsheetDocument = SpreadsheetDocument.Create(mStream, SpreadsheetDocumentType.Workbook)
Dim workBPart As WorkbookPart = spreadSheetDoc.AddWorkbookPart
Dim workSPart As WorksheetPart = workBPart.AddNewPart(Of WorksheetPart)()

I following this article for sending SMS it is a winform application.. I have referenced all the Dll's to my asp.net application. I use an aspx page to detect a mobile device connected to a PC..... But it alwys shows COM 'n' Port could not be opened.
using SMS;
using GsmComm.GsmCommunication;
using GsmComm.PduConverter;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
GsmCommMain comm = new GsmCommMain(6, 9600, 300);
comm.Open();
if (!comm.IsConnected())
{
Response.Write("No Phone Connected");
}
else
{
SmsSubmitPdu pdu = new SmsSubmitPdu("test", "+919999999999", "");
CommSetting.comm.SendMessage(pdu);
}
}
}
EDIT:
I use the web development server that ships with Visual Studio... If go to Control Panel -> Phones & Modems -> Modems i could see my mobile connected in com6.. i have tested the winform application it works fine.Is this the answer? ASP.NET pages are supposed to work.What is happening over here is that when you click on open_com button, the ASP.NET page posts back to itself, executes the event handler i.e., opensthe port. Then when the page finishesprocessing the post back, it is unloaded. At this point the COM1 objects is also destroyed.
