本文介绍了在JAVA环境下如何实现IDEA对称加密算法。由于电子商务和电子政务的普及，安全加密技术在其中应用非常广泛，对安全加密技术的要求也很高。目前在JAVA环境下实现IDEA加密具有很多的优势，因为JAVA是基于面向对象的编程语言,并且由于它的平台无关性能被大量应用于Internet的开发。-This paper presents the Java environment IDEA how to achieve symmetric encryption algorithm. As e-commerce and e-government popular, security encryption technology, which is widely used for security encryption technology requirements is also high. In Java environment under IDEA encryption has many advantages, because Java is based on object-oriented programming language, and because it is platform independent performance was widely used in Internet development.

DES与RSA算法的解析与推演。不是单纯理论的讲解，带着一些应用的角度让对密码学有兴趣的人能很容易理解略显深奥的密码算法。-DES and RSA algorithms with analytic deduction. Not purely theoretical explanations, with the perspective of some applications of cryptography to allow those who are interested can easily understand the slightly esoteric cipher.

aes加密算法。用delphi语言实现。位数为128。-Aes encryption algorithm. Delphi use language. Median 128.

vc编写的rsa加密软件，包括源码．有兴趣的同志可以另做界面-vc prepared rsa encryption software, including source code. Comrades who are interested can do the other interface

本次实现采用流水线结构，分析子密钥与原始密钥的直接关系，利用组合逻辑同时产生16个子密钥，总体上既兼顾了效率，又不占用太多资源，经仿真测试，完全通过。
