摘　　要：阐述了DES发展现状及对网络安全的重要意义,并在此基础上对DES算法原理进行详细的介绍和分析。通过C#应用DES算法加解密的具体实现,进一步加深对DES算法的理解,论证了DES算法具有加密快速且强壮的优点,适合对含有大量信息的文件进行加密,同时分析了DES算法密钥过短(56位)所带来的安全隐患。This paper expounds the development situation of DES and the significance of the network security, and based onthe principle of DES algorithm are introduced and analyzed in detail. Through the implementation of C# application of DESencryption and decryption, further deepen the understanding of DES algorithm, the DES algorithm has the advantages ofrapid and strong encryption, suitable for containing a large amount of information file encryption, and analyzed the DES algorithm＇s key is too short （56bit） security risks brought about by the.
