QT mingw 编译Crypto++ 5.6.4

1、下载Crypto++ v5.6.4，并解压；

https://codeload.github.com/weidai11/cryptopp/zip/CRYPTOPP_5_6_4

2、新建文件 cryptopp564 ，把解压后的文件全部复制进去，不要子文件夹路径；

3、随便复制一个其它项目的.pro到当前目录下，粘贴后，将这个文件重命名为 CryptoPPLib.pro  编辑器打开，内容清空，粘贴以下内容；

CryptoPPLib.pro文件内容如下：

    LIBS += -lws2_32
    CONFIG += warn_off

4、删除当前目录下 GNUmakefile 此文件；

5、编译库lib

 5. 1、 用QTCreator打开CryptoPPLib.pro；

5. 2、取消，shadow build勾选；

5.3、执行qmake

5.4、点击最下放构建，钉锤标志（这是生成lib，不需要执行 run）即可。

5.5、点击箭头处切换到release，继续执行1-4步。

5.6、最终会生成，debug和release两个文件里，各有一个.a和一个.dll，如下图；

至此，基于Crypto++的lib编译完成。

二.测试QT调用；

1、新建一个qt项目；

2、main目录下新建文件夹cryptopp；

3、在cryptopp文件夹里，新建 Include 和 Lib 共两个子文件夹；

4、将原cryptopp564文件夹下所有头文件（.h）文件复制到 Include文件夹；

5、将原来5.6的debug和release文件，复制到Lib文件夹里;

将以下内容追加到，当前测试项目，.pro文件结尾；

CONFIG += warn_off
LIBS += -lws2_32
 win32:CONFIG(release, debug|release): LIBS += -L$$PWD/release/ -lCryptoPPLib
    else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/cryptopp/Lib/debug/ -lCryptoPPLib
    else:unix: LIBS += -L$$PWD/ -lCryptoPPLib
DEPENDPATH += $$PWD/
INCLUDEPATH+=$$PWD/cryptopp/Include

6、包含头文件，调用，测试，如下：

#include <QCoreApplication>
#include <qdebug.h>
#include <iostream>

#define CRYPTOPP_DEFAULT_NO_DLL
#include <dll.h>
#ifdef CRYPTOPP_WIN32_AVAILABLE
#include <windows.h>
#endif
#include "base32.h"
#include "base64.h"
#include <filters.h>
using namespace CryptoPP;
using namespace std;

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    string src="让世界爱上中国造！";
    string dst;
    StringSource(src, true, new Base64Encoder(new StringSink(dst)));
    qDebug()<<"encode src="<<src.c_str()<<endl;
    cout<<"encode dst="<<dst<<endl;

    string src2="6K6p5LiW55WM54ix5LiK5Lit5Zu96YCg77yB";
    string dst2;
    StringSource(src2, true, new Base64Decoder(new StringSink(dst2)));
    cout<<"decode src2="<<src2<<endl;
    qDebug()<<"decode dst2="<<dst2.c_str()<<endl;

    return a.exec();
}

结果如下： base64编码 base64解码
