AES_CMAC
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. VC6 upload files to complete the project directory . AES encryption algorithm that is Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as Rijndael encryption method, a block encryption standard adopted by the U.S. federal government . This standard is used to replace the original DES, has been widely analyzed and multi used around the world . After five years of the selection process , the Advanced Encryption Standard by the American National Institute of Standards and Technology (NIST) on November 26, 2001 Posted in FIPS PUB 197, and May 26, 2002 became effective standards . AES algorithm based on permutation and substitution operations. Data re- arrangement is arranged , is replaced with a replacement unit of data to another . AES using several different methods to perform alignment and replacement operations. AES is an iterative , symmetric key block password , it can use 128, 192, and )

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
