摘要

文中在Microsoft Visual Studio2005集成开发环境下

用C#实现了基于信息摘要函数的文件完整性检测工具.该工具使用CRC32、MD5和SHA1信息摘要函数

通过计算文件的数字文摘值

向系统管理员提供文件完整性检测功能

从而为发现入侵提供依据.实验表明

该工具在对多个文件的完整性测试过程中

计算出的CRC32、MD5、SHA1数字文摘值正确无误.

Abstract

We design and implement the file integrity checking system based on message digest function

using C# language in Microsoft Visual Studio 2005 integrated development environment.The system provides file integrity detection function by calculating the message digest value of CRC32、MD5 and SHA1

so as to provide the evidence of invasion discovery for the system administrator.The experimental evaluations show that the system generates the correct message digest value of CRC32、MD5 and SHA1 in the testing process of multiple files integrity.
