DES数据加密算法的VC程序实现

DES Encryption Algorithm's Implementation Based on VC

本文介绍了DES数据加密算法(Data Encryption Standard)的一般原理,同时对如何使用VC程序实现改算法作了阐述,并在DES原始算法实现的基础上(因为它一次只能加解密64位)进行扩充和改进,可以方便地加密/解密任何格式、任何大小的文件.

The papers introduces the principle of Des encryption algorithm, and it brings forward implementing DES by VC. The papers extends and improves the DES based on orginal DES algorithm(because it can encrypts or decrypts 64 bit), now it encrypts or decrypts the file of any sizes and format.
