文档介绍:摘要
自20世纪90年代以来,随着计算机网络和信息技术的发展,信息安全在各领域发挥着越来越重要的作用,其中密码学已成为信息安全技术的核心。本文研究课题是基于非对称算法----RSA的数据文件加解密系统的设计与实现,其主要实现的功能有以下几个:(1)数据文件加密;(2)数据文件解密;(3)密钥管理;(4)用户管理。此系统主要以java2EE作为开发基础,使用myeclipse作为开发工具,以MySQL作为数据库,使用JAVA语言开发,实现可以对文件进行RSA加密操作的窗体应用程序。本论文给出关键类类图、整个应用程序的结构描述文档、关键模块流程图、较详细的接口文档、部分功能实现截图。对应用程序进行测试,对测试结果进行分析研究,进而对应用程序进行改进,对关键算法进行尽可能的优化,最终得到一个在windows运行的可以用指定密钥对任意文件进行RSA加密并可解密的完整应用程序。

Abstract
Since the 1990s , with the development works and information technology in all areas of information security plays an increasingly important role , which has e the core cryptographic information security technology . This article is based on research ---- RSA asymmetric algorithms plus data file decryption system design and implementation , and its main function has the following : (1) data file encryption ; (2) a data file decryption ; (3) the key management ; (4) user management . RSA algorithm is now recognized in theory and practical application of the most mature plete a public-key cryptosystem , which is the first not only for data encryption can be used for digital signature algorithm , public key cryptosystems representatives. This system is mainly to java2EE as a development base , using the myeclipse as a development tool for MySQL as a database, using the JAVA language development, implementation can file Forms application RSA encryption operations. The key classes chart shows , the entire application schema document , the key modules flowcharts , more detailed interface documentation , all of the source code. The application for testing, analysis and study of the test results , and thus to improve the application of key algorithms as optimization , finally get a run in the windows key can be used to specify any file RSA encryption and decryption plete application .
