If I change this line of code in NotificationConnection.cs;

certificate = new X509Certificate2(p12File, p12FilePassword);

to

certificate = new X509Certificate2(p12File, p12FilePassword,
X509KeyStorageFlags.MachineKeySet);

...it works.

Hmm, so you don't have the public and private key pairs both in the p12 file 
then?  If you're telling it to check 
the machinekeyset that seems like it would be the case.  I'm not sure this is a 
bug really, maybe a feature 
enhancement to allow the ability to use the machine key store instead of just a 
file...

I included the certificate and key from my keychain.  The dev cert from Apple.
Do I need to include more?

Hi Jon,

I am also having the same issue with Windows Server 2003.  I run your sample,
apns.Notification.test on the same server.  Everything worked as expected.  
After

Hi,

I have the same problem. When I upload this to my hosting provider I get this 
error. When I change the 
NotificationConnection.cs it doesn't run, it just shows you a loading bar on 
the bottom of IE and it isn't 
working. How can I solve this?

Best Regards,

Kenneth

Fixed, the sample was using p12File for the constructor of NotificationService
instead of p12Filename

I am having Mocha as my web hoster hosting my application & iam indeed using 
the latest Apns-Sharp-1.0.3.0 but I see this issue still exists.

this is my constructor
string p12Filename = 
System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, p12File);

        NotificationService service = new NotificationService(sandbox, p12Filename, p12FilePassword, 1);

I do not have any issues on trying to send a message from my dev/build box or 
for that matter from my staging server.I see this issue after I upload a copy 
from my staging to production(mocha).

I just ran into the same problem with the latest version of the code, like 
others. The code was running perfectly fine both on my local machine (a Windows 
7 box) and on our dev server at work (a Windows 2003 box). However, as soon as 
I deployed the code to our production server (a Windows 2008 virtual machine on 
Amazon EC2), it started failing with a similar CryptographicException with the 
message "Object not found".

After numerous searches, I found similar references to the use of 
"X509KeyStorageFlags.MachineKeySet" as one is constructing the X509Certificate2 
object (for example, see the first reply here: http://goo.gl/b6t2 ). Lo and 
behold, I changed the library code (as the original poster did) to use this and 
the problem went away on the production server.

I should note that, I don't have any imported certificates, that I am actually 
trying to import the certificate from the .p12 file. I guess the problem arises 
when a web project is trying to perform a cryptographic operation, but the 
operation somehow tries to find the private key in the current user set (which 
seems to be the default). However, for such cases, it seems the MachineKeySet 
can manage to load it fine. The MSDN documentation also states that 
MachineKeySet implies "Private keys are stored in the local computer store 
rather than the current user store." (See: http://goo.gl/f2z3 )

Thank you very much, paracycle. Your comment saved my day. To be specific, this 
constructor in NotificationChannel.cs needed to be changed to:

  public NotificationChannel(string host, int port, byte[] p12FileBytes, string p12FilePassword)
  {
   Host = host;
   Port = port;

   connected = false;
   firstConnect = true;
   ReconnectDelay = 3000;
   ConnectRetries = 6;

   //Need to load the private key seperately from apple
   if (string.IsNullOrEmpty(p12FilePassword))
    certificate = new X509Certificate2(p12FileBytes, "", X509KeyStorageFlags.MachineKeySet);
   else
    certificate = new X509Certificate2(p12FileBytes, p12FilePassword, X509KeyStorageFlags.MachineKeySet);

   certificates = new X509CertificateCollection();
   certificates.Add(certificate);
  }

This is running on Rackspace Cloud Sites (used to be Mosso).

Greetings,

Thank you allara.starmist for your contribution. We changed our local source of 
the apns library and now it works.

@APNS Team
It would be great if you could change the code into the original source 
binaries you provide for downloading.

Best regards from Austria,
