Question

I wanted to know where exactly in xcode do I place a x.509 certificate that I have. Taking the example from here:
http://code.google.com/p/cocoaasyncsocket/downloads/detail?name=CertTest.zip&can=1&q=

I wanted to be able to communicate with a secure server I have running. I just cant seem to add the certificate in and everytime I do, my mac opens up a keychain window asking m if the certificate belongs to any of my system (other than my project) settings. So I wanted to know where do I place it in my project and how I would use it(I guess the project at the link would help with that)

If you are using NSURLConnection for connecting to your server then you should implement next methods in your delegate:

- (BOOL)connection:(NSURLConnection *)conn canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace;
// A delegate method called by the NSURLConnection when something happens with the 
// connection security-wise.  We defer all of the logic for how to handle this to 
// the ChallengeHandler module (and it's very custom subclasses).


- (void)connection:(NSURLConnection *)conn didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
// A delegate method called by the NSURLConnection when you accept a specific 
// authentication challenge by returning YES from -connection:canAuthenticateAgainstProtectionSpace:. 
// Again, most of the logic has been shuffled off to the ChallengeHandler module; the only 
// policy decision we make here is that, if the challenge handle doesn't get it right in 5 tries, 
// we bail out.
