Crypto++学习总结---AES

静态库下载连接Cryp++ lib 下载

AES 使用方法 如下：

[cpp] view
plaincopy





//For AES encrypt

#include "default.h"

#include "cryptlib.h"

#include "filters.h"

#include "bench.h"

#include "osrng.h"

#include "hex.h"

#include "modes.h"

#include "files.h"



using namespace CryptoPP;

#pragma comment(lib, "cryptopp\\lib\\cryptlib.lib")

string message = "Hello World!";

//CBC - PADDING

//AES-CBC Encrypt(ONE_AND_ZEROS_PADDING)

true,
