需要为现有的一个程序增加一些安全特性：
These new features include:
. Securing the key exchange protocol to be resistant to man-in-the-middle
and session hijacking attacks.
. Implementation of functionality to securely store sensitive information
(e.g. private keys) to a file.
. Implementation of the payment protocol.
. Implementation of any remaining security features that were not implemented
or completed in Part 1.
