Qt 计算文件的 md5 值

https://www.jianshu.com/p/fe774becf239

QString fileMd5(const QString &sourceFilePath) {

    QFile sourceFile(sourceFilePath);
    qint64 fileSize = sourceFile.size();
    const qint64 bufferSize = 10240;

    if (sourceFile.open(QIODevice::ReadOnly)) {
        char buffer[bufferSize];
        int bytesRead;
        int readSize = qMin(fileSize, bufferSize);

        QCryptographicHash hash(QCryptographicHash::Md5);

        while (readSize > 0 && (bytesRead = sourceFile.read(buffer, readSize)) > 0) {
            fileSize -= bytesRead;
            hash.addData(buffer, bytesRead);
            readSize = qMin(fileSize, bufferSize);
        }

        sourceFile.close();
        return QString(hash.result().toHex());
    }
    return QString();
}
