<?php

include("chilkat.php");

$crypt = new CkCrypt2();

$path = 'c:/someDir/example.p7m';

// ------------------------------------------------------------------------
// The OpaqueVerifyBytes method is deprecated:

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

$outData = new CkByteData();

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

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

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

// If the opaque signature is validated, the contents of bd are replaced with the original data that was signed.
$success = $crypt->OpaqueVerifyBd($bd);
