ASP.NET Sample Listing Certificates available to the ASPNET Process.

This C# ASP.NET Example demonstrates how to use the Chilkat .NET certificate classes (CreateCS, CertStore, and Cert) to list the certificates available to an ASP.NET program.

<font face=courier size=2>
		// What certificates are visible to this process?  This program lists them…
		// The ASP.NET process will probably be running under the ASPNET account.
		// You can verify by checking the System.Environment.UserName property.
	
		Chilkat.CreateCS ccs = new Chilkat.CreateCS();
	
		// First check the Current User Certificate Store.
		// These are certificates specific to the current logged-on user.
		TextBox4.Text = "Current User Certificate Store…….\r\n";
	
		Chilkat.CertStore cs = ccs.OpenCurrentUserStore();
		int i;
		int n = cs.NumCertificates;
		if (n == 0) TextBox4.Text = TextBox4.Text + "No Certificates in Current User Store.\r\n";
		for (i=0; i<n ; i++)
		{
		    Chilkat.Cert cert = cs.GetCertificate(i);
		    TextBox4.Text = TextBox4.Text + cert.SubjectDN + "\r\n";
	
		    // Do we have the private key?
		    // The private key is required for creating a digital signature
		    // or decrypting.  It is not required for signature verification
		    // or encrypting.
		    if (cert.HasPrivateKey())
		    {
			TextBox4.Text = TextBox4.Text + "  ++ HAS Private Key\r\n";
		    }
		    else
		    {
			TextBox4.Text = TextBox4.Text + "  — NO Private Key\r\n";
		    }
		}	
	
		TextBox4.Text = TextBox4.Text + "Local Machine Certificate Store…….\r\n";
	
		// What’s in the local system (i.e. local machine) certificate store?
		cs = ccs.OpenLocalSystemStore();
		n = cs.NumCertificates;
		if (n == 0) TextBox4.Text = TextBox4.Text + "No Certificates in Local Machine Store.\r\n";
		for (i=0; i<n; i++)
		{
		    Chilkat.Cert cert = cs.GetCertificate(i);
		    TextBox4.Text = TextBox4.Text + cert.SubjectDN + "\r\n";
	
		    // Do we have the private key?
		    if (cert.HasPrivateKey())
		    {
			TextBox4.Text = TextBox4.Text + "  ++ HAS Private Key\r\n";
		    }
		    else
		    {

		    }
