PHP Extension Requires Chilkat v11.0.0+

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');
