VB程序设计在网络安全中的应用
摘要：计算机网络中传输的信息涉及政府、军事、经济、文教等诸多领域，其中很多是敏感信息甚至是国家机密，所以难免会吸引夹自世界各地的“黑客”及各种病毒的攻击。这除了计算机网络固有的设计缺陷外，很多是因为计算机语言本身的安全漏洞或用户的不正当使用造成的。为此，本文首先讨论了登录口令的设置和处理，接着阐述了网络数据加密解密，最后分析了代理(Agent) 的实现。因此本文具有深刻的理论意义和广泛的实际应用。

Programming of Visual Basic Apply in the Network Security
Abstract：Computer network transmit information relate to the government、military affairs、economy、culture and education and so on, in this information has many sensitivity information including the nation secret, so hacker and many of sorts virus attack this information. Besides of the design bug of the computer network, a large number of is the security leak and malfeasance use of the computer language.So, in this paper,firstly discussed the log password,then expatiated network data encrypt,finally analysis the implement of the Agent. It has deeply signification in theory and extensive value in applications.
