首先創(chuàng)建Crypto__test 工程。
在已編譯好的Cryptopp561中找到Debug文件夾 下的cryptlib.lib 將其改名為cryptlibd.lib后放到上級(jí)目錄中。在Release文件夾下找到cryptlib.lib 將其放到上級(jí)目錄中（不改名）。目的是為以后引用方便。
在 工具——選項(xiàng) ——目錄中 選擇 Include--files 導(dǎo)入CRYPTOPP561 （方便以后程序中引用） 接著選擇Library files 導(dǎo)入CRYPTOPP561 （這就是問什么剛才需要把兩個(gè)庫(kù)文件放在上級(jí)目錄的原因----方便引用）
在工程———設(shè)置 ——調(diào)試 下 分類中選擇 Code Generation 然后選擇Multithreaded (多線程) 此步非常重要，若不設(shè)置將會(huì)出現(xiàn)2005錯(cuò)誤。
將如下代碼放入 StdAfx.h 文件中 （主要是編譯時(shí)用到得頭文件和類庫(kù)）
- #include <iostream>
-
-
- #ifdef _DEBUG
- # pragma comment( lib, "cryptlibd" )
- #else
- # pragma comment( lib, "cryptlib" )
- #endif
最后在Crypto__test.cpp 中貼入如下源碼：
-
-
-
- #include "stdafx.h"
-
- #include "rsa.h"
- #include "osrng.h"
- #include "integer.h"
- #include "sha.h"
- #include "hex.h"
- #include "filters.h"
-
- int main(int argc, char* argv[])
- {
-
-
-
- std::string message( "I think computer viruses should count as life. I think it\n" \
- " says something about human nature that the only form of\n" \
- " life we have created so far is purely destructive. We've\n" \
- " created life in our own image." );
-
-
-
- CryptoPP::AutoSeededRandomPool rng;
-
-
-
- CryptoPP::InvertibleRSAFunction keys;
- keys.GenerateRandomWithKeySize( rng, 384 );
-
-
-
- CryptoPP::Integer n = keys.GetModulus();
- CryptoPP::Integer p = keys.GetPrime1();
- CryptoPP::Integer q = keys.GetPrime2();
- CryptoPP::Integer d = keys.GetPrivateExponent();
- CryptoPP::Integer e = keys.GetPublicExponent();
-
-
-
- std::cout << "RSA Parameters:" << std::endl;
- std::cout << " n: " << n << std::endl;
- std::cout << " p: " << p << std::endl;
- std::cout << " q: " << q << std::endl;
- std::cout << " d: " << d << std::endl;
- std::cout << " e: " << e << std::endl;
- std::cout << std::endl;
-
-
-
- CryptoPP::RSASS<
- CryptoPP::PKCS1v15, CryptoPP::SHA
- >::Signer signer( keys );
-
-
-
- std::cout << "Message:" << std::endl;
- std::cout << " " << message << std::endl;
- std::cout << std::endl;
-
-
- byte* signature = new byte[ signer.MaxSignatureLength() ];
- if( NULL == signature ) { return -1; }
-
-
- size_t length = signer.SignMessage( rng, (const byte*) message.c_str(),
- message.length(), signature );
-
-
-
- std::string encoded;
- CryptoPP::HexEncoder encoder( new CryptoPP::StringSink( encoded ),
- true , 2 , ":" );
- encoder.Put( signature, length );
- encoder.MessageEnd();
-
-
-
- std::cout << "Signature:" << std::endl;
- std::cout << " " << encoded << std::endl;
- std::cout << std::endl;
-
-
-
- CryptoPP::RSASS<
- CryptoPP::PKCS1v15, CryptoPP::SHA
- >::Verifier verifier( signer );
-
- bool result = verifier.VerifyMessage( (const byte*)message.c_str(),
- message.length(), signature, length );
-
-
-
- if( true == result )
- {
- std::cout << "Message Verified" << std::endl;
- }
- else
- {
- std::cout << "Message Verification Failed" << std::endl;
- }
-
-
-
- if( NULL != signature ) { delete[] signature; }
-
- return 0;
- }
運(yùn)行結(jié)果如下：
到此有關(guān)crypto++環(huán)境搭建工作基本上已經(jīng)完成。若遇到此文中沒有提及的問題時(shí)可百度查閱相關(guān)資料。
