RSA算法，主要讲述算法的原理和过程，设计到加密解密，和溢出处理，初级学习RSA用(RSA algorithm, the algorithm mainly about the principle and process design to the encryption and decryption, and overflow processing, the primary study used RSA)

rsa 实现代码，运用大数算法#include "afx.h" #include "Integer.h" #include <string> #include <iostream> using namespace std //构造大数对象并初始化为零 CInteger::CInteger() { m_nLength=1 for(int i=0 i<BI_MAXLEN i++)m_ulValue[i]=0 } //解构大数对象 CInteger::~CInteger() { } /*大数比较 调用方式：N.Cmp(A) 返回值：若N<A返回-1；若N=A返回0；若N>A返回1 */ int CInteger::Cmp(CInteger& A)(#include "afx.h" #include "Integer.h" #include <string> #include <iostream> using namespace std //构造大数对象并初始化为零 CInteger::CInteger() { m_nLength=1 for(int i=0 i<BI_MAXLEN i++)m_ulValue[i]=0 } //解构大数对象 CInteger::~CInteger() { } /*大数比较 调用方式：N.Cmp(A) 返回值：若N<A返回-1；若N=A返回0；若N>A返回1 */ int CInteger::Cmp(CInteger& A))

通过C语言实现的AES CMAC加密和解密算法。上传文件为完整的VC6工程目录。AES加密算法即密码学中的高级加密标准（Advanced Encryption Standard，AES），又称Rijndael加密法，是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES，已经被多方分析且广为全世界所使用。经过五年的甄选流程，高级加密标准由美国国家标准与技术研究院 （NIST）于2001年11月26日发布于FIPS PUB 197，并在2002年5月26日成为有效的标准。AES 算法基于排列和置换运算。排列是对数据重新进行安排，置换是将一个数据单元替换为另一个。AES 使用几种不同的方法来执行排列和置换运算。 AES 是一个迭代的、对称密钥分组的密码，它可以使用128、192 和 256 位密钥，并且用 128 位（16字节）分组加密和解密数据。与公共密钥密码使用密钥对不同，对称密钥密码使用相同的密钥加密和解密数据。通过分组密码返回的加密数据的位数与输入数据相同。迭代加密使用一个循环结构，在该循环中重复置换和替换输入数据。(AES CMAC encryption and decryption algorithm C language.

一个实现DES加解密算法的小程序，编程实现DES算法的加密过程、脱密过程和16个内部密钥生成过程(An implementation of DES encryption and decryption algorithm applet, programming encryption algorithm DES implementation process, from secret process and the 16 internal key generation process)

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

可以对文件进行加解密，这是自己编写的实验作业(Can encrypt and decrypt files, it is their job to prepare experimental)

椭圆曲线密码体制及其在电子银行中的应用，对椭圆曲线的加解密应用具有很好参考价值(Elliptic curve cryptography and its application in e-banking, a good reference value of the elliptic curve encryption and decryption application )

本文使用ECC加密AES的密钥，再由AES加密明文内容，AES加密强度大，速度快，但是密钥更新繁琐和不安全，由强度很大的非对称密钥算法对AES密钥加密，结合了两方的优点(this programme combine the ECC with AES.using the ECC to cipher the AES key,and using the AES to cipher the m)
