用JAVA做的模拟电梯的程序,是自己做的

目前企业面临的计算环境和过去有很大的变化，许多数据资源能够依靠网络来远程存取，而且越来越多的通讯依赖于公共网络公共网络（如 Internet），而这些环境并不保证实体间的安全通信，数据在传输过程可能被其它人读取或篡改。-currently facing the enterprise computing environment and past a great change, many data resources to be able to rely on remote network access, and more and more dependent on public communications networks public networks (such as the Internet), which environment is not a guarantee of the security entities communications, data transmission possible by other people read or tampered with.

md5加密算法，适用于linux开发环境。-md5 encryption algorithm applied to linux development environment.

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)
