Hash the Contents of a File (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a file using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. PHP ActiveX

<?php

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

$crypt = new COM("Chilkat.Crypt2");

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

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

// Let's examine the hash as a hex string.
$sb = new COM("Chilkat.StringBuilder");
$sb->AppendEncoded($hashBytes,'hex');
print 'SHA256 hash = ' . $sb->getAsString() . "\n";
