Workaround for the deprecated Crypt2.HashBytes method

Shows how to replace the deprecated HashBytes method. (Chilkat is moving away from the use of CkByteData.) C

    //  ------------------------------------------------------------------------
    //  The HashBytes method is deprecated:

    inData = CkByteData_Create();
    CkByteData_loadFile(inData,path);

    outData = CkByteData_Create();

    success = CkCrypt2_HashBytes(crypt,inData,outData);

    //  ------------------------------------------------------------------------
    //  Workaround.
    //  (Chilkat is moving away from using CkByteData)

    bdIn = CkBinData_Create();
    CkBinData_LoadFile(bdIn,path);

    CkCrypt2_putEncodingMode(crypt,"base64");

    CkCrypt2_Dispose(crypt);
    CkByteData_Dispose(inData);
    CkByteData_Dispose(outData);
    CkBinData_Dispose(bdIn);
