QxtBlowfish doesn't work

[fab_74]

Hello, I'm trying to use QxtBlowfish in order to encrypt data, but it just doesn't work. Even with documentation's example.

QxtBlowfish fish;
   fish.setKey("foobar");
   QByteArray data("barblah");
   data = fish.encrypt(data);
   qDebug() << data << data.length();
   data = fish.decrypt(data);
   qDebug() << data << data.length();

QxtBlowfish fish;
   fish.setKey("foobar");
   QByteArray data("barblah");
   data = fish.encrypt(data);
   qDebug() << data << data.length();
   data = fish.decrypt(data);
   qDebug() << data << data.length();

To copy to clipboard, switch view to plain text mode 

This code compiles, but will output :

"" 0
"" 0

So it looks like it doesn't work at all... Any idea?

Thank you in advance.
