Having trouble decrypting a well-formed cipher text using Crypto++

Question

Background

I\'ve been struggling with decrypting an apparently well-formed cipher text for about a day. Assume we\'ve got the following hex-encoded cipher text whi

Answer 1

The hexEncode function seems to misbehave:

QString CryptoUtils::hexEncode(QString text)
{
    byte *bytearray = (byte *) text.toLatin1().data();
    int length = text.toLatin1().length();

    return hexEncode(bytearray, length);
}

Should be replaced with:

QString CryptoUtils::hexEncode(QString text)
{
    byte *bytearray = (byte *) text.toStdString().data();
    int length = text.length();

    return hexEncode(bytearray, length);
}
