说明：  本文用JAVA语言开发了一个基于Misty1算法的加密软件，该软件能对文件进行加密和解密。在具体实现时，首先分析了Misty1算法的基本结构，设计出相应的实施方法，正确实现了该算法，其次，设计了一个图形用户界面，最后对软件进行了测试，验证了实现方法的正确性。
(This paper develops an encryption software based on Misty1 algorithm with Java language, which can encrypt and decrypt files. In the specific implementation, firstly, the basic structure of Misty1 algorithm is analyzed, the corresponding implementation method is designed, and the algorithm is implemented correctly. Secondly, a graphical user interface is designed, and finally the software is tested to verify the correctness of the implementation method.)
