This is my first post at stackoverflow.com, so if i do something wrong just let me know. So onto the problem.
I have a C# server currently running System.Net.Socket Sockets similar to the sample code Microsoft provided here.
I also have an Objective-C iPad client running NSInputStream/NSOutputStream bound to CFReadStream/CFWriteStream.
At present with only username/password authentication sent via an XML Serialized Object the client and server can communicate without any issues.
The problem I now have is that the communication has to be secure, and talking to clients, SSL encryption would be acceptable. However, I don't think they would accept just the "Server Certificate" as good enough. So I am trying to get the iPad client to use a "Client Certificate". I would like to enable true mutual authentication.
If I can't achieve mutual authentication, a third party VPN Software could be the better solution to secure the communication.
I haven't completed the conversion yet, but I have found a few articles that give me good examples of this, but there are no examples that fit my situation for client side certificates on the iPad. The samples that i have found are:
Apple Developer site that shows how to use SSL, but no client certificate
