    Exclamation How to convert string hex values to its real binary values?

    How can I convert in an elegant way a loooong hex string data from its hex representation to the real (binary) representation?

    I have this:
    QByteArray *inputdata = new QByteArray ("020707010001030103030700090508003520080480183500 "); (only hex numbers in the string)
    And I want to have a pointer to this in memory, like: 0x020707010001030103030700090508003520080480183500

    I want to feed the inputdata to the QCryptographicHash but in this case I feed the QCryptographicHash with the asci representation of 02070701000103010303070009...
    what is: 3032303730373031303030313033303130333......

    Please notice that in this case we can not use toLong or toInt methods!

    Thanks for any idea!
