PHP Extension for Windows, Linux, MAC OS X,
Alpine Linux, Solaris, OpenBSD, FreeBSD,
and Linux armhf/aarch64

<?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");

$crypt = new CkCrypt2();

//  Any string argument automatically begins the 30-day trial.
$success = $crypt->UnlockComponent('30-day trial');
if ($success != true) {
    print $crypt->lastErrorText() . "\n";
    exit;
}

$s = 'The quick brown fox jumps over the lazy dog';

$crypt->put_HashAlgorithm('sha1');
$crypt->put_EncodingMode('hex');

//  Other possible EncodingMode settings are:
//  "quoted-printable", "base64", and "url"

$hash = $crypt->hashStringENC($s);
print 'SHA1: ' . $hash . "\n";

//  Hash using MD2
$crypt->put_HashAlgorithm('md2');
$hash = $crypt->hashStringENC($s);
print 'MD2: ' . $hash . "\n";

//  Hash using MD5
$crypt->put_HashAlgorithm('md5');
$hash = $crypt->hashStringENC($s);
print 'MD5: ' . $hash . "\n";

//  Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

//  Hash using SHA-256
$crypt->put_HashAlgorithm('sha256');
$hash = $crypt->hashStringENC($s);
print 'SHA256: ' . $hash . "\n";

//  Hash using SHA-384
$crypt->put_HashAlgorithm('sha384');
$hash = $crypt->hashStringENC($s);
print 'SHA384: ' . $hash . "\n";

//  Hash using SHA-512
$crypt->put_HashAlgorithm('sha512');
$hash = $crypt->hashStringENC($s);
print 'SHA512: ' . $hash . "\n";

//  Hash using HAVAL
//  There are two additional properties relevant to HAVAL:
//  HavalRounds, and KeyLength.
//  HavalRounds can have values of 3, 4, or 5.
//  KeyLength can have values of 128, 160, 192, 224, or 256
$crypt->put_HashAlgorithm('haval');
$crypt->put_HavalRounds(5);
$crypt->put_KeyLength(256);
$hash = $crypt->hashStringENC($s);
print 'Haval: ' . $hash . "\n";

//  Hashes for "The quick brown fox jumps over the lazy dog"
