At the moment it is not set, so it is using whatever the default is.
Here is a short example of what I am using:

    server {
         listen 443;

         ssl                  on;
         ssl_certificate      /etc/nginx/ssl/data.crt;
         ssl_certificate_key  /etc/nginx/ssl/data.key;
         ssl_protocols SSLv3 TLSv1;

         # Make sure we verify client side SSL
         ssl_verify_client on;
         ssl_client_certificate /etc/nginx/ssl/data.pem;
    }

So I guess there is not much we can do about that.
