修改本程序中的U盘的序列号后，程序可以变成你自己的独立的Ｕ盘启动密匙，　只能你的Ｕ盘才能打开程序　不需要往Ｕ盘中存入任何文件，就可实现用Ｕ盘加密程序.只能通过你的U盘启动你的程序 程序中有详细的注释(Encrypt your program by a soul U-disk without saving anything in you disk Modify the program, U-disk serial number, the program can become your own independent U disk key, only you can open U disk U disk does not need to deposit any file, can be achieved U disk encryption program)

密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.
