将 QByteArray 转换为 QString

Question

I want to encrypt the data of a database and to do this, I used AES_128 in this link for encryption.

The result of encryption is a QByteArray and the QByteArray is saved on the text file in the correct shape and I could decode it correctly, but and I need to convert it to the QString and reverse to QByteArray to store and read it on the Sqlite DB. I tried some options like

QByteArray encodedText; QString DataAsString = QString(encodedText);

and

string DataAsString1 = encodedText.toStdString();

and

QString DataAsString = QTextCodec::codecForName("UTF-8") >toUnicode(encodedText);

and other solutions like this link , but the outputs of these options aren't in the correct way. Because after casting, I couldn't convert the encoded text to decoded correctly.

This is the input string of encoded text: "\x14r\xF7""6#\xFE\xDB\xF0""D\x1B\xB5\x10\xEDx\xE1""F" and these are the outputs for the different options: \024r�6#���D\033�\020�x�F and \024r�6#���D\033�\020�x�F

Does anybody suggestion about the right conversion?

try to use this: QString QString::fromUtf8(const QByteArray &str)
