$crypt = new CkCrypt2();

$cert = new CkCert();
// ...
// Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
// 
$success = $crypt->SetSigningCert($cert);

$crypt->put_HashAlgorithm('sha256');

// ------------------------------------------------------------------------
// The SignBytes method is deprecated:

$inData = new CkByteData();
$inData->loadFile($path);

$outData = new CkByteData();

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

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

$bdIn = new CkBinData();
$bdIn->LoadFile($path);

$crypt->put_EncodingMode('base64');
$base64_sig = $crypt->signBdENC($bdIn);

// If you want to access the bytes...
$bdSig = new CkBinData();
$bdSig->AppendEncoded($base64_sig,'base64');
