// The MacBytes method is deprecated:

$inData->loadFile($path);

$outData = new CkByteData();

$success = $crypt->MacBytes($inData,$outData);

// Workaround.

$bdIn->LoadFile($path);

// Set to any supported Chilkat encoding: base64, hex, base64url, hex_lower, etc.
$crypt->put_EncodingMode('base64');
$mac_base64 = $crypt->macBdENC($bdIn);
