相关疑难解决方法(0)

我需要一个字符串加密的例子(在C++中 - >我在linux-Ubuntu上工作)和aes-cbc256以及填充:PKCS7请帮忙.

对于以下代码,如何将IV设置为0并将键值设置为字符串值？我还想添加pkcs7填充.我正在使用crypto ++ lib(在Linux中)

// Driver.cpp   
//      

#include "stdafx.h"    
#include "cryptopp/dll.h"    
#include "cryptopp/default.h"    
#include "crypto++/osrng.h"    
using CryptoPP::AutoSeededRandomPool;    

#include <iostream>    
using std::cout;    
using std::cerr;       

#include <string>    
using std::string;       

#include "crypto++/cryptlib.h"    
using CryptoPP::Exception;        

#include "crypto++/hex.h"    
using CryptoPP::HexEncoder;    
using CryptoPP::HexDecoder;        

#include "crypto++/filters.h"    
using CryptoPP::StringSink;    
using CryptoPP::StringSource;    
using CryptoPP::StreamTransformationFilter;        

#include "crypto++/aes.h"    
using CryptoPP::AES;       

#include "crypto++/ccm.h"    
using CryptoPP::CBC_Mode;       

#include "assert.h"        

int main(int argc, char* argv[])    
{    
    AutoSeededRandomPool prng;        

    byte key[ AES::DEFAULT_KEYLENGTH ];    
    prng.GenerateBlock( key, sizeof(key) );        

    byte iv[ AES::BLOCKSIZE];    
    iv[AES::BLOCKSIZE] = 0;    
    //prng.GenerateBlock(iv, …
