(PHP ActiveX) Hash the Contents of a String (SHA256 and other hash algorithms)
Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.
<?php
// This example requires the Chilkat Crypt API to have been previously unlocked.
// See Unlock Chilkat Crypt for sample code.
$crypt = new COM("Chilkat_9_5_0.Crypt2");
// Choose the hash algorithm.
// Can be "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
$crypt->HashAlgorithm = 'sha256';
// The byte representation of the string matters when hashing.
// Tell Chilkat that we want to use the utf-8 byte representation.
$crypt->Charset = 'utf-8';
$hashBytes = $crypt->HashString('They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.');
// Let's examine the hash as a hex string.
$sb = new COM("Chilkat_9_5_0.StringBuilder");
$sb->AppendEncoded($hashBytes,'hex');
print 'SHA256 hash = ' . $sb->getAsString() . "\n";
