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.

1、 实验要求：用高级语言实现IDEA算法的加密-1, the experimental requirements: use of high-level language implementation of the IDEA encryption algorithm

该源码描述了DES加密算法的硬件语言实现方式-The source described the hardware DES encryption algorithm realize the way language

鉴于单纯设置一个计数器易被查出，通过修改使其不起作用。我们设计的程序可以通过数据文件，软件执行前通过关键字找到计数基数，然后计算和判别，如果在合理范围，则设定新的关键字，将计数基数放在新关键字指定的位置，并执行子程序 则启动自毁程序。

java自行开发rsa-developed rsa
