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, …

以下是在C上使用cbc和pkcs7填充(和密码)加密的aes256的代码(Windows和C++(使用libcrypto ++的Ubuntu).加密结果不一样.为什么？

C#:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Security.Cryptography;


public static class AESEncryption
{
    public static string Encrypt(byte[] PlainTextBytes, byte[] KeyBytes, string InitialVector)
        {
            try
            {
                byte[] InitialVectorBytes = Encoding.UTF8.GetBytes(InitialVector);
                RijndaelManaged SymmetricKey = new RijndaelManaged();
                SymmetricKey.Mode = CipherMode.CBC;
               // SymmetricKey.Padding = PaddingMode.PKCS7;
                ICryptoTransform Encryptor = SymmetricKey.CreateEncryptor(KeyBytes, InitialVectorBytes);
                MemoryStream MemStream = new MemoryStream();
                CryptoStream CryptoStream = new CryptoStream(MemStream, Encryptor, CryptoStreamMode.Write);
                CryptoStream.Write(PlainTextBytes, 0, PlainTextBytes.Length);
                CryptoStream.FlushFinalBlock();
                byte[] CipherTextBytes = MemStream.ToArray();
                MemStream.Close();
                CryptoStream.Close();
                //return ByteToHexConversion(CipherTextBytes);

                return Convert.ToBase64String(CipherTextBytes);
            } …
