    Description

      The SHA3 family of message digest is a modified version of Keccak. Qt seems to be calculating Keccak, not SHA3:

          qDebug() << QCryptographicHash::hash("abc", QCryptographicHash::Sha3_224).toHex();

      outputs 

      "c30411768506ebe1c2871b1ee2e87d38df342317300a9b97a95ec6a8"

      (wrong: correct is e642824c3f8cf24ad09234ee7d3c766fc9a3a5168d0c94ad73b46fdf).
