Static Public Member Functions
static quint32	GetCrcFromData (const quint8 *dataPtr, int dataSize)
	Get 32-bit CRC value for the given memory block.
static quint32	GetCrcFromStream (const ByteStream &byteStream)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
static quint32	GetCrcFromFile (const QString &fileName)
	Get 32-bit CRC value for a given file.

Static Protected Member Functions
static void	UpdateCrc (const quint8 &byte, quint32 &dwCrc32)
	Update CRC value for the new input.
