一、

使用库：https://github.com/bricke/Qt-AES

二、代码举例

#include <QCryptographicHash>
void MainWindow::on_pushButton_clicked()
{
    QAESEncryption encryption(QAESEncryption::AES_128, QAESEncryption::ECB, QAESEncryption::ZERO);

    QString key="12345";
    QString date="20200730";
    QString data="BFEBFBFF000406F1Z9ABXEMP"+date;

    QByteArray hashKey = QCryptographicHash::hash(key.toUtf8(), QCryptographicHash::Md5);
    QByteArray encodedText = encryption.encode(data.toUtf8(), hashKey);
    QString str_encode_text=QString::fromLatin1(encodedText.toBase64());
    qDebug()<<"encodedText:"<<str_encode_text;



    //QAESEncryption encryption(QAESEncryption::AES_128, QAESEncryption::ECB, QAESEncryption::ZERO);
    QByteArray hashKey2 = QCryptographicHash::hash(key.toUtf8(), QCryptographicHash::Md5);
    QByteArray decodedText = encryption.decode(QByteArray::fromBase64(str_encode_text.toLatin1()), hashKey2);
    qDebug()<<"decodedText:"<<QString::fromLatin1(decodedText);
    
}
