<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$crypt = new CkCrypt2();

// Choose the hash algorithm.
// Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
$crypt->put_HashAlgorithm('sha256');

$hashBytes = new CkByteData();
$success = $crypt->HashFile('qa_data/jpg/starfish.jpg',$hashBytes);

// Let's examine the hash as a hex string.
$sb = new CkStringBuilder();
$sb->AppendEncoded($hashBytes,'hex');
