C++数据校验之异或校验

QString checkXorH(QByteArray data)
{
    QStringList strData;
    QString rdata = data;
    int  checksum = 0;
    for(int i = 0; i < rdata.size()/2; i++){
        strData.append(rdata.mid(i*2,2));
    }
    for (int i = 0;i < rdata.size()/2;i++)
    {
        checksum = checksum ^ strData[i].toInt(nullptr,16);
    }
    strData.clear();
    return QString::number(checksum,16).toUpper();
}

QString checkXord(QString data)
{
    QStringList strData;
    int  checksum = 0;
    data = data.toLatin1().toHex();
    for(int i = 0; i < data.size()/2; i++){
        strData.append(data.mid(i*2,2));
