Description: Network Encryption chat software to achieve the function has two main aspects: the first one is a network chat function, as long as two or more hosts to access the Internet, but the software is installed, the two sides that can communicate with each other, LAN broadcast/group broadcast feature allows multi-party chat is also very easy to implement. The second function is an optional feature, the information that you think needs to be kept confidential to the situation, you can choose to encrypt sent, even if other people see your chat history, it is only a series of characters. The encryption method I used here is the MD5 algorithm, due to its irreversibility is relatively safe to implement.
