该系统是一个比较简单的高校人事管理系统，详细内容可以见文档说明。 PS：本人是vc＋＋的初学者，希望能通过审核，加入这个大家庭，与大家共同学习进步！

设计一个可以顺计时和倒计时的秒表。要求计时的范围为00.0S~99.9S，用三位数码管显示。用VHDL语言-Designed to be a cis-timing and countdown stopwatch. Required time ranges from 00.0S ~ 99.9S, with three digital tube display.

随着密码分析技术的提高，新的数据加密标准AES取代了过时的DES。文章在阐述AES/RSA加密算法的基础上，分别给出了利用AES/RSA实现客户端/服务器端网络数据传输的加密流程。最后在比较AES算法和RSA算法基础上，将AES与RSA相结合提出一种新的数据加密方案。-analysis technology improvements, new data encryption standard AES replaced the outdated DES. The article described AES/RSA encryption algorithm on the basis of the difference is the use of AES/RSA achieve client/server network data encryption process. Finally in comparison AES and RSA algorithm, based on AES and RSA will be combined, a new data encryption program.
