基于DES的文件加密系统设计

Designing of Document Encryption System Based on DES Algorithm

为了提高网络中数据传输的安全性,对数据文件加密是一种常用的有效手段。利用C#作为文件加密系统的开发平台,采用面向对象程序设计方法,并基于DES加密算法实现了文件的加密、解密、密码设置等功能。测试结果表明,该文件加密系统可对ASCII文件正确、快速加解密,且密文文件很难破解,该系统可广泛用于网络通信领域中。

In order to ensure data transmitting security on net,a popular and sometimes effective means is that data in the file is encrypted.Based on the development environment C#,and object oriented programming,the document encryption system is designed. The main functions of the system include encryption,decryption and password settings etc. This result indicates that the encryption system can encrypt and decrypt to document with early and correct,the encrypted data is hard to decipher also.The system can be widely used in the field of network communication.
