Give Access To Private Key In Certificate In Store?
Apr 9, 2010
I have an ASP.NET application that accesses private key in a certificate in the certificates store. On Windows Server 2003 I was able to use winhttpcertcfg.exe to give private key access to the NETWORK SERVICE account. How do I give permissions to access a Private Key in a certificate in the certificate store (Local ComputerPersonal) on a Windows Server 2008 R2 in an IIS 7.5 website? I've tried giving Full Trust access to "Everyone", "IIS AppPoolDefaultAppPool", "IIS_IUSRS", and everyother security account I could find using the Certificates MMC (Server 2008 R2). However the below code demonstrates that the code does not have access to the Private Key of a certificate that was imported with the private key. The code instead throws and error everytime the private key property is accessed.
I am trying to use an X509Certificate within an ASP.NET web service within the Rackspace Cloud. I have a feeling the certificate stores on the cloud nodes maybe causing problems. I also have a question related to this with the exception that I am receiving at SslStream.AuthenticateAsClient Exception when using iPhone Apple Push Notification Provider (apns-sharp) C# Within the apns-sharp project I was using the following code:
certificate = new X509Certificate2(p12File)
However I received an exception and changing the code to the following resolved the X509Certificate2 exception. The new code is as follows:
certificate = new X509Certificate2(p12File, String.Empty, X509KeyStorageFlags.MachineKeySet);
I would like to know if I can use an X509Certificate2 within ASP.NET without using a certificate store? Would the certificate stores be causing problems with the Rackspace Cloud nodes?
Update #1 Rackspace tell me that access to the Local Machine Certificate store is not permitted. Is there any other way to bypass using the certificate store? Maybe using a third party library?
Quick question: is it possible to retrive a users certificate store i.e. list all of the client's Personal Certificates?
Just to be clear, I am talking about the certificates installed on the clients machine, not the servers. I have managed to list the server's certificates, but so far have been unsuccesful with the above.
While developing and ASP.NET application in C# or VB using Visual Studio 2005/2008/2010 (Not a problem in 2003), if I create a new method automatically by double-clicking on a control in the designer or picking the new method in the code editor dropdowns (VB only), the access modifier is always protected instead of private. This is annoying because my developers have to manually change the method to private every time.
I want to store a X509 certificate to a user store in Novell viathe ".NET C# LDAP Library" that Novell has developed [URL]I can store different entries like givenName, commonName, mail, description etc. etc. Everythings works fine :)But I can't store a certificate correctly because the final encoding of the certificate will be failed.I've tried to send the entire certificate as HEX and Base64 in strings and bytes but the final encoding will still be failed.
[Code]....
So my question is:Anyone who knows how I should encode the certificate before sending it?
Let's assume our users in their office using Internet explorer to sign some Web Pages using their client certificate imported into the Internet explorer browser (let s assume no other browser is used)
what is a good approach/architecture for validating the client certificate (Internet Explorer), how to send that certificate or the signed form to the server and how do we verify the signature
Should we use smart client approach integrated to the web application or some silverlight or so or is web form/web pages enough to implement this security requirement ?
IBecuase if they the UrlReferrer is my applicatin then i want them to allow access to a file.Otherwise not.I know the urlReferrer is null if you go directly to the link, but thats not possible.In my test solution it works great, but if i put it online i got null values, sometimes he gives a value but mosly its null...
In my application i have 4 screens such as page1.aspx, page2.aspx, page3.aspx, Page4.aspx. I have created user Settings Web Form where the admin Creates username and password for users with access only for particular pages. I have used check boxes to select their accessibility while creating user setting.
I want a piece of code for asp.net 3.5 using visual basic. and i am using MS access database.
I have two three text boxes and 2 image upload controls and a submit button.
I want a piece of code in which a user can upload images and store it in our database . i want an asp.net visual basic working code. also i need query behind the submit button.
I am using ajax html editor to write a text. I can view it without having problem but I am incapeble of storing it in a Ms Access database. which type do I need to use for this? I tried memo and OleObject type and both didn't work. I used the blow code for that.
In my web application i have 8 screens such as page1.aspx, page2.aspx, page3.aspx........Page8.aspx. I have created user Settings Web Form where the admin Creates username and password for users with access only for particular pages. I have used check boxes to select their accessibility while creating user setting. How can i limit the access of the users only to certain tabs.(All these pages are in the tabs).
I'm totally stuck. I've tried many ways. I have a webapplication deployed on Win2003 with IIS 6.0. The website needs to access:
D:data on another PC.
I've sucessfully created a virtual directory (using local credentials to the data PC) in IIS and I am fully able to browse and view all the files. So now the webserver is: WebserverData.
In my behind code, I call filestream f = (Server.MapPath("WebserverDatasomedata.txt")));
and it tells me access to that location: \webserverdatasomedata.txt is DENIED. BUT I am able to browse on the Win2k3 IIS server.
I've set impersonation to true and used local username and password of the data PC. I've configured IIS to use the same username password.
I'm quite newbie and i need to give access to the website at a very low cost, but just few people, how did you guys manage it, to hide the connection link to the public. I mean is there a better way or not to manage this. I don't know if I'm clear. What would be the cheapest way to manage this user account?
I have a project that has 4 pages and from each page have several link buttons to go each of the other pages. I would like to declare these url in the web.config file and give them a name and access from vb.net code behind.
Since we can access the private data member of base class in the derived class with the help of friend function. How can we do the same in C# asp.net? I mean whats the alternative of friend function in C# asp.net
im trying to store a date in an Access database i set up the column in the db to be type Date/Time and have the following code to attempt to insert into itDim objTest As New OleDb.OleDbCommand("INSTERT INTO orderForm (OrderDate) VALUES (@OrderDate)", objConn) objTest.Parameters.Add(" OrderDate", DateTime.Now) Dim objTestExec As OleDb.OleDbDataReader = objTest.ExecuteReader()
however it yields the following error when i execute invalid SQL statement; expected 'DELETE', 'INSERT', 'PROCEDURE', 'SELECT', or 'UPDATE'.ive also had a variety of other errors with my efforts so im not really sure what the deal is here

I'm adding support for multiple language to my site. I've found many places in my renderers that have hard-coded strings I'll need to address.
I seem to have a couple different options of fixing this... one would be to use the standard .NET approach and store strings in a resource file. I'm not liking this because my Sitecore translators can't get to that... and also because I don't think Sitecore sets the Culture by default? Which I believe is how ASP.NET knows which language to use from the resource file.
Another option would be to add fields for all these strings in my Sitecore templates so they are visible to translators in Content Editor. But this seems like a huge hassle... there are many, many places where I would have to update my templates solely to store UI element strings.
What is the recommended or usual way an ASP.net web application(in C# language) can store/access values that are needed accross the various pages in a website. For example a basic company website might need the company's name and other related information available to multiple pages. Where do I declare these variables/values and how do I access them. Coming from c++ application programming I would usually store such data in a Singleton class object.
I need to keep access settings to different web pages inside of my asp.net application. These setting are logins and passwords for those pages. Is it safe enough to keep them in web.config in section?
