Unable to load libcrypto.dylib in iOS Simulator

I've created an Xcode app for iOS simulator, which is basically the template code, save for this:

- (void)viewDidLoad { [super viewDidLoad];

  void *handle = dlopen("/usr/lib/libcrypto.0.9.8.dylib", 1);

  if (!handle) {

    printf("[%s] Unable to load dylib: %s\n", __FILE__, dlerror());

  }

}

Which results in a message that contains:

"Unable to load dylib: dlopen(/usr/lib/libcrypto.0.9.8.dylib, 1): no suitable image found. Did find: /usr/lib/libcrypto.0.9.8.dylib: mach-o, but not built for iOS simulator"

Using the file command reports that the file supports i386 and x86_64 architectures.

Is iOS simulator just blocking the loading of this file, or is it genuinely not built for simulator? If the latter, how does one tell the difference?
