<?php

include("chilkat.php");

$crypt = new CkCrypt2();

// Specifies how the original data bytes are converted to characters
$crypt->put_Charset('utf-8');

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

// ------------------------------------------------------------------------
// The OpaqueVerifyString method is deprecated:

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

$originalText = $crypt->opaqueVerifyString($inData);

// ------------------------------------------------------------------------
// 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);

// Indicate how the bytes are converted to chars by passing the charset.
$originalText = $bd->getString('utf-8');
