HMAC is a much simpler implementation, providing the same benefits as RSA, avoids additional steps and keeps the code simpler. This patch also additionally - Implements PutObjectURL API. - GetObjectURL, PutObjectURL take TargetHost as another argument for generating URL's for proper target destination. - Adds experimental TLS support for JSON RPC calls.
