Hash Algorithms: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

How to create hashes (message digests) for strings.

<?php

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

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

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

$crypt->HashAlgorithm = 'sha1';
$crypt->EncodingMode = 'hex';

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

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

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

//  Hash using MD5
$crypt->HashAlgorithm = 'md5';
$hash = $crypt->hashStringENC($s);
print 'MD5:' . "\n";
print $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->HashAlgorithm = 'sha256';
$hash = $crypt->hashStringENC($s);
print 'SHA256:' . "\n";
print $hash . "\n";

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

//  Hash using SHA-512
$crypt->HashAlgorithm = 'sha512';
$hash = $crypt->hashStringENC($s);
print 'SHA512:' . "\n";
print $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->HashAlgorithm = 'haval';
$crypt->HavalRounds = 5;
$crypt->KeyLength = 256;
$hash = $crypt->hashStringENC($s);
print 'Haval:' . "\n";
print $hash . "\n";
