1、概述
源码放在文章末尾
该项目主要用于生成密钥，下面是demo演示：
项目部分代码如下：
#pragma execution_character_set("utf-8")#include "frmmain.h"
#include "ui_frmmain.h"
#include "qmessagebox.h"
#include "qfile.h"
#include "qprocess.h"

{ui->setupUi(this);this->initForm();qDebug() << this->getCpuName() << this->getCpuId() << this->getDiskNum();
}frmMain::~frmMain()
{delete ui;
}void frmMain::initForm()

}QString frmMain::getWMIC(const QString &cmd)

}QString frmMain::getCpuId()

}QString frmMain::getDiskNum()
{return getWMIC("wmic diskdrive where index=0 get serialnumber");
}QString frmMain::getXorEncryptDecrypt(const QString &data, char key)

}void frmMain::on_btnClose_clicked()
