实现移位密码（扩展凯撒密码），用键盘接收明文和密钥，屏幕打印密文。-Achieve translocation password (Extension Caesar password), use the keyboard to receive explicit and key, screen printing ciphertext.

编程中获得会话密钥匙非常重要的 MSDN 展示了一种使用私钥的方法。 但是微软的这个在MSDN中例子相当的长。 本文下面介绍的这个方法不仅更快而且更有效 -Programming cryptographic key conversation was very important MSDN demonstrated a method of using the private key. But in Microsoft"s MSDN examples longer. Presented below is the method not only faster and more effectively

一个非常好的ASE代码，通过实验证明能编译通过-A perfect AES program code, and it can be run after translation and edition.

　提出一种改进的禁忌搜索算法来求解背包问题。该算法基于禁忌搜索技术,并采用I&D策略,同时设计了两种针对局 部最优解的变异算子。改进后的算法能有效地弥补标准禁忌算法对初始解依赖的缺陷,同时也避免了搜索停滞的现象。通过对具 体实例和随机问题的测试,表明改进后的禁忌搜索算法有更好的性能。 关-An improved tabu search algorithm to solve knapsack problem. The algorithm is based on tabu search techniques, using I & D strategies, while designed for the local optimal solution of the two kinds of mutation operator. The improved algorithm can effectively compensate for the standard tabu search algorithm depends on the initial solution defect, but also to avoid the phenomenon of search stagnation. Through specific examples and random-question test, indicating that the improved tabu search algorithm has better performance. Guan
