win10+QT5.15+Crypto++8.6 完整配置开发

1、准备如下几项内容：

        a、WIN10环境下的QT5.15.2安装包，QTCreator对应版本安装。（自行安装）

        b、Crypto++8.6安装包下载，官网：https://www.cryptopp.com/，这里没选择最新的8.7是因为mingw-32编译后的库文件使用有问题，有错误，但是8.6用同样的方式编译就可以正常使用。

2、使用QT环境编译CryptoPP 8.6，解压源码包，命令行模式下：qmake -project生成 .Pro文件，修改内容：TEMPLATE = lib，增加：DEFINES += CRYPTOPPLIB_LIBRARY，QMAKE_CXXFLAGS += "-msse4.2"
QMAKE_CXXFLAGS += "-mavx"
QMAKE_CXXFLAGS += "-mavx2"
QMAKE_CXXFLAGS += "-mpclmul"
QMAKE_CXXFLAGS += "-maes"
QMAKE_CXXFLAGS += "-msha"
LIBS += -lws2_32

3、删除无用信息：

           TestPrograms/test_x86_via_sha.cpp

4、命令模式执行：

    qmake

    mingw32-make all

  注意：此处的 mingw32-make.exe文件要跟qtcreator开发环境下的项目编译环境一直，这样才能保证编译后的dll和a文件能正确调用。

编译无错误生成：libcryptopp860.a 和 cryptopp860.dll文件。

5、新建Qt开发项目，可以是widgets或者console程序，目录下新建目录（根据个人喜好）：libs\cryptopp\include 和libs\cryptopp\lib。

6、拷贝crypto8.6源码目录下的所有h文件到上面的include目录。拷贝编译后的libcryptopp860.a 和 cryptopp860.dll文件到lib目录。

7、编辑程序项目pro文件，

增加：

INCLUDEPATH += $$PWD/libs/cryptopp/include
DEPENDPATH += $$PWD/libs/cryptopp/include

LIBS +=  $$PWD/libs/cryptopp/lib/cryptopp860.dll

8、至此crypto的引用已经完成，下面代码例子：

头文件引用：

#include

#include "libs/cryptopp/include/cryptlib.h"
#include "libs/cryptopp/include/des.h"
#include "libs/cryptopp/include/filters.h"
#include "libs/cryptopp/include/modes.h"

#include "libs/cryptopp/include/hex.h"
#include "libs/cryptopp/include/secblock.h"

名称空间：
using namespace std;
using namespace CryptoPP;

以DES-CBC-pkcs7-编解码为例（参照网上的例子）：

string DES_CBC_Encryption(string sKey, std::string sIV, const char *plainText) {
  std::string strCipherText;

  try {
    // 填key
    CryptoPP::SecByteBlock key(CryptoPP::DES::MAX_KEYLENGTH);
    memset(key, 0x30, key.size());
    sKey.size() <= CryptoPP::DES::MAX_KEYLENGTH
        ? memcpy(key, sKey.c_str(), sKey.size())
        : memcpy(key, sKey.c_str(), CryptoPP::DES::MAX_KEYLENGTH);

    // 填iv
    CryptoPP::byte iv[CryptoPP::DES::BLOCKSIZE];
    memset(iv, 0x30, CryptoPP::DES::BLOCKSIZE);
    sIV.size() <= CryptoPP::DES::BLOCKSIZE
        ? memcpy(iv, sIV.c_str(), sIV.size())
        : memcpy(iv, sIV.c_str(), CryptoPP::DES::BLOCKSIZE);

    CryptoPP::DES::Encryption desEncryption((CryptoPP::byte *)key,
                                            CryptoPP::DES::MAX_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption(desEncryption,
                                                                iv);

    CryptoPP::StreamTransformationFilter cbcEncryptor(
        cbcEncryption,
        new CryptoPP::HexEncoder(new CryptoPP::StringSink(strCipherText)),
        CryptoPP::BlockPaddingSchemeDef::BlockPaddingScheme::PKCS_PADDING);

    cbcEncryptor.Put((CryptoPP::byte *)plainText, strlen(plainText));
    cbcEncryptor.MessageEnd();
  } catch (const CryptoPP::Exception &e) {
    std::cout << e.what() << std::endl;
  }
  return strCipherText;
}
string DES_CBC_Decryption(std::string sKey, std::string sIV,
                               const char *cipherText) {
  std::string strPlainText;

  try {
    // 填key
    CryptoPP::SecByteBlock key(CryptoPP::DES::MAX_KEYLENGTH);
    memset(key, 0x30, key.size());
    sKey.size() <= CryptoPP::DES::MAX_KEYLENGTH
        ? memcpy(key, sKey.c_str(), sKey.size())
        : memcpy(key, sKey.c_str(), CryptoPP::DES::MAX_KEYLENGTH);

    // 填iv
    CryptoPP::byte iv[CryptoPP::DES::BLOCKSIZE];
    memset(iv, 0x30, CryptoPP::DES::BLOCKSIZE);
    sIV.size() <= CryptoPP::DES::BLOCKSIZE
        ? memcpy(iv, sIV.c_str(), sIV.size())
        : memcpy(iv, sIV.c_str(), CryptoPP::DES::BLOCKSIZE);

    CryptoPP::CBC_Mode::Decryption cbcDecryption(
        (CryptoPP::byte *)key, CryptoPP::DES::MAX_KEYLENGTH, iv);

    CryptoPP::HexDecoder decryptor(new CryptoPP::StreamTransformationFilter(
        cbcDecryption, new CryptoPP::StringSink(strPlainText),
        CryptoPP::BlockPaddingSchemeDef::BlockPaddingScheme::PKCS_PADDING));

    decryptor.Put((CryptoPP::byte *)cipherText, strlen(cipherText));
    decryptor.MessageEnd();
  } catch (const CryptoPP::Exception &e) {
    std::cout << e.what() << std::endl;
  }

  return strPlainText;
}

正常使用：

编码：

string strCBCEncryp = DES_CBC_Encryption(strKey, strIV, period_of_validity.c_str());

解码：

string strCBCDecryp = DES_CBC_Decryption(strKey, strIV, strCBCEncryp);

正常调用无问题。

9、程序打包，生成的exe文件在debug或者relase目录下，需要将cryptopp860.dll拷贝到目录下，a文件貌似不需要，然后执行：windeployqt.exe 程序执行文件名，补充相关的库文件和相关资料，此目录下就是完整的执行环境可以直接打包成一个执行文件，这里可以使用Enigma Virtual Box，挺方便，可以压缩大小并打包到一个exe文件中，具体百度，有很多资料说明。

9、总结几个问题：

9.1、之前在编译crypto问题上花了很多时间，官方默认的源码支持vsC++编译生成库文件，但是在QT环境下不能用（可能也有办法但是没深研究），QT下编译需要使用mingw，如果装了多个qt环境或者mingw环境就会很麻烦，需要调整系统环境变量达到编译一致性。

9.2、项目软件编译后执行目录下可以只保留dll文件，a文件不需要（容量也很大），另外pro文件里配置LIBS +=  $$PWD/libs/cryptopp/lib/cryptopp860.dll，不要用

LIBS +=  $$PWD/libs/cryptopp/lib/libcryptopp860.a，原因是使用a文件会出现windows环境下输出命令行信息，必须配对使用config += console才能正常使用，但是我们使用widgets模式时不需要显示命令窗口，每次启动软件会跟随打开一个命令窗口，很影响感受，因此在windows下我们引用dll库即可。

9.3、windeployqt.exe打包程序必须跟qt开发环境中使用的编译环境版本一致，否则会导致补充dll等库文件的程序无法定位程序输入点，因此建议系统里只装一个版本的qt，并使用对应的mingw编译环境。

10、最后，以上内容有自己总结也有借鉴网上查询资料，难免有纰漏，如有错误欢迎执教，关于crypto8.7的编译为什么不能用需要再研究一下，按理说不应该跟8.6差别这么大，哪位知道的同学欢迎指教。

下一步涉及Linux和Android环境下的编译使用，也研究了一下基本差不多，不会太难，大家自行查找即可。
