RSA加密算法的C预言实现，对一张灰度图进行加密，然后再解密(RSA encryption algorithm in C prophecy fulfilled, encrypt and then decrypt a grayscale)

vc++写的ElGamal加密系统，能够对简单的数字进行加密。(The ElGamal encryption systems, vc++ write simple digital encryption.)

说明：  六种加密算法源码，包括CRC32校验，DES加密，MD5，rsa数字签名，RSA演示，简单加密(Six encryption algorithm source code, including the CRC32 checksum, DES encryption, MD5, rsa digital signature, RSA presentation, simple encryption)

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

MD5加密算法，可以加密包含二进制数据的数据块，生成16字节MD5加密数据。(MD5 encryption algorithm to encrypt data blocks that contain binary data, generates a 16-byte MD5 encrypted data.)

国密算法sm实现 sm2数字签名 密钥交换，sm3，sm4，已实现、求sm2第四部分公钥加密c实现源码。。。江湖救急。。。(sm2，sm3，sm4。。。)

无须解压密码,利用自己设计的程序同样可以实现对控制面板内容的控制,(Do not need to unzip password, to use its own design program can also realize the control of the content of the control panel,)

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))

基于VB的M5数学密码算法源码,有需要的就下载吧。(VB-based M5 mathematical algorithm source code, there is a need to download it.)

分析RSA算法的应用现状，论证文件加密应用RSA算法的可行性和意义。设计一套完整实用的RSA文件加密解决方案，具体编码实现。对RSA算法进行研究，从常规RSA算法出发，用C++实现RSA加密算法类库，并在32位windows平台封装成组件。在.Net平台引用此组件，实现可以对任意文件进行RSA加密 (Analysis of Application of RSA algorithm, file encryption application demonstration of the feasibility of RSA algorithm and significance. Design of a complete file encryption RSA practical solutions to achieve specific coding. Research on the RSA algorithm, starting from the conventional RSA algorithm using C++ class library to achieve RSA encryption algorithm, and in 32-bit windows platform components into a package. In. Net platform, referred to this component, the realization of arbitrary files on RSA encryption)
