(PHP Extension) Compute Glacier SHA256 Linear Hash of a File
Computes the Amazon Glacier SHA256 linear hash for a file.
<?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();
// The "linear hash" is simply the SHA256 hash of the file bytes.
$crypt->put_HashAlgorithm('sha256');
// Return the hash in lowercase hexidecimal format.
$crypt->put_EncodingMode('hexlower');
$linearHashHex = $crypt->hashFileENC('qa_data/jpg/penguins.jpg');
print 'SHA256 linear hash = ' . $linearHashHex . "\n";
