Give Access to Certificate in Store

[mikker_123]

I just want to add X509Certificate to store, and enable user to read it's private key. I snatched part of code from here but it won't work. private static void PlaceInStore(X509Certificate2 cert) { X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine); try { store.Open(OpenFlags.ReadWrite); using (RSACryptoServiceProvider csp = cert.PrivateKey as RSACryptoServiceProvider) { CspKeyContainerInfo kci = csp.CspKeyContainerInfo; CryptoKeySecurity cks = kci.CryptoKeySecurity; cks.SetAccessRule(new CryptoKeyAccessRule("ARCHITECT\\testuser", CryptoKeyRights.FullControl, AccessControlType.Allow)); } if (!store.Certificates.Contains(cert)) store.Add(cert); } finally { store.Close(); } } Help anyone?

I once had to do a similar thing - adding a certificate to a particular certificate store. And I discovered something very strange: Nothing happened if I used the Add method, but if instead I used the AddRange method it worked. AddRange takes as parameter a collection of certificates. Just create a new collection, add your certificate to it and call AddRange. And never lose your hope. :)

Dunno... Add method works great for me. Anyways I found some kind of solution googling, it works, but I don't like it. Anyways, if someone has better solution please post, until then I'll use this:

    private static void PlaceInStore(X509Certificate2 cert)
    {
        X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);

        try
        {
            store.Open(OpenFlags.ReadWrite);

            if (!store.Certificates.Contains(cert))
                store.Add(cert);

            int indexInStore = store.Certificates.IndexOf(cert);
            cert = store.Certificates\[indexInStore\];

            AddAccessToCertificate(cert, "ARCHITECT\\\\testuser");
        }
        finally
        {
            store.Close();
        }
    }

    private static void AddAccessToCertificate(X509Certificate2 cert, string user)
    {
        RSACryptoServiceProvider rsa = cert.PrivateKey as RSACryptoServiceProvider;

        if (rsa != null)
        {
            string keyfilepath =
                FindKeyLocation(rsa.CspKeyContainerInfo.UniqueKeyContainerName);

            FileInfo file = new FileInfo(keyfilepath + "\\\\" +
                rsa.CspKeyContainerInfo.UniqueKeyContainerName);

            FileSecurity fs = file.GetAccessControl();

            NTAccount account = new NTAccount(user);
            fs.AddAccessRule(new FileSystemAccessRule(account,
            FileSystemRights.FullControl, AccessControlType.Allow));

            file.SetAccessControl(fs);
        }
    }

    private static string FindKeyLocation(string keyFileName)
    {
        string text1 =
        Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
        string text2 = text1 + @"\\Microsoft\\Crypto\\RSA\\MachineKeys";
        string\[\] textArray1 = Directory.GetFiles(text2, keyFileName);
        if (textArray1.Length > 0)
        {
            return text2;
        }
        string text3 =
        Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
        string text4 = text3 + @"\\Microsoft\\Cry

Hi Mikker, I know its been a longgggggggggggggggggggggg time since you have replied to this post but I bumped into your post and I wanna do exactly what you have mentioned...but the problem I am facing is that I am confused as to how to call the PlaceInStore() function ? I tried using HTTPHandlers in WCF service but it didnt work so I am kinda stuck now. Pleas help ?? Anybody??? :) Naeem

How can we work if we have to access the remote server certificates. For remote server it is showing an exception keyset not found Thanks in Advance. Please enlighten me
