一个文件加密的例子

快速MD5碰撞生成器，王小云改进版。这个生成器根据“构造前缀碰撞法”可以生成两个不同的文件，而这两文件的md5 sum却是一样的。 MD5 Collision Generator(win32 .exe) MD5 Collision Generator(source) -Fast MD5 collision generator, Xiaoyun Wang, improved version. The generator according to "construct the prefix collision" system can generate two different files, while the md5 sum of these two documents is the same.

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.

本程序提供密钥产生的一些基本数学实现 用c++实现-This procedure provides the key generated by using some basic math c++ Realize

这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入。-This is an easy to use the MD5 of the C++ Category this category can be added to the console program can also be used in MFC, and it provides a detailed error handling function, is a safe type. MD5 is a routine procedure of MFC to support the two input strings and documents.

 ECC（Elliptic Curves Cryptography）加密算法是一种公钥加密算法，与主流的RSA算法相比，ECC算法可以使用较短的密钥达到相同的安全程度。此文档是160bit的C++源代码.
