java语言编写基于DES加密算法的TCP聊天程序-java language based on the DES encryption algorithm for TCP chat program

基于DES加密的TCP聊天程序，在linux环境运行成功后，双方可以实现聊天，聊天内容是经过加密处理的，即便是被截获也不会泄露消息内容-DES encryption of TCP-based chat program, after a successful run linux environment, the two sides can achieve chat, chat content is encrypted, even if the message is intercepted and

使用DES加密算法，实现了TCP聊天程序的加密，在linux环境下运行。(Using the DES encryption algorithm, the TCP chat program is encrypted and run in the Linux environment.)

运用RSA公钥加密和DES对称加密，实现TCP聊天程序的加密(Using RSA public key encryption and DES symmetric encryption to realize the encryption of TCP chat program)
