一个DES加密算法的实现-a DES encryption algorithm implementation

一本介绍密码学现代知识的学习资料，对于密码算法编程方面很有用。-A description of the study of modern knowledge of cryptography information programming for the cryptographic algorithm is useful.

算法参考于《密码编码学及网络安全》上关于RSA加密算法的定义。相关程序在Visual C++ 6.0上能正确运行（估计在其他C语言编程环境下也能运行吧），程序里面详细写上了注解，希望能够给你带来帮助。

密码学中的Miller Rabin素性检测算法。人工编写，用这个来学习或者是交作业，绝对是过关利器。-Cryptography Miller Rabin primality testing algorithm. Artificial preparation, use this to learn or交作业is definitely a sharp object boundary.

今天我们学习了des对称加密算法这是一个des算法的C++实现-This is a des !

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.
