这是一个RSA的简单实现算法,用的是C++语言实现的.-This is a simple realization of the RSA algorithm is used in the C language.

使用迭代方程Xn+1=Asin2(Xn-XB)生成混沌序列{Xi}，需输入A和Xb值，不同的值产生不同的加密效果，但是仅在混沌区内的加密效果最好。在Microsoft Visual Studio .NET 2003上调试成功，用C++语言编写-use an iterative equation Xn Asin2 = (Xn- XB) generated chaotic sequence (Xi) need input A and isolate value, different values in different encryption effect, but only in the chaotic region of encryption is the best. In Microsoft Visual Studio.NET 2003 Debugger success C Language

用C语言实现的RSA算法，各个部分模块，都有详细介绍。密钥生成、大素数产生、素数判断、参数的选取，都有，用C语言实现的RSA算法。
