基于DES算法的文件加密研究

Research on File Encryption Based on DES Algorit hm

在网络时代,计算机应用到了各个方面,与之匹配的网络技术也在快速发展,网络间通信数据大量增加。传输的数据如用户个人信息、商务数据或者其他方面的文件,都涉及每位用户的机密,因此采用加密技术保护文件就显得很重要。为了提高网络中数据传输的安全性,笔者利用C#作为文件加密软件的开发软件,通过针对对象进行程序设计,在数据加密以及密码设置上采用DES加密算法,能够满足用户对文件的安全性要求。

In the network era,computers are applied to all aspects,and the matching network technology is also developing rapidly,and the communication data between networks is increasing greatly.The transmitted data,such as personal information,business data or other documents,all involve the confidentiality of each user,so it is very important to protect the documents with encryption technology.In order to improve the security of data transmission in the network,the author uses C#as the development software of the file encryption software,through the object-oriented programming,in the data encryption and password setting,the DES encryption algorithm can meet the user’s requirements for file security.
