Workaround for the deprecated Crypt2.OpaqueSignBytesENC method

Shows how to replace the deprecated OpaqueSignBytesENC method. (Chilkat is moving away from the use of CkByteData.) PHP Extension

<?php

include("chilkat.php");

$success = false;

$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);

$path = 'c:/someDir/example.dat';

// ------------------------------------------------------------------------
// The OpaqueSignBytesENC method is deprecated:

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

$crypt->put_EncodingMode('base64');
$base64_sig = $crypt->opaqueSignBytesENC($inData);

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

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

// The contents of bd are replaced with the opaque signature.
$success = $crypt->OpaqueSignBd($bd);

$base64_sig = $bd->getEncoded('base64');
