<?php

include("chilkat.php");

$crypt = new CkCrypt2();

$crypt->put_CryptAlgorithm('aes');
$crypt->put_CipherMode('cbc');
$crypt->put_KeyLength(256);
// ...

// ------------------------------------------------------------------------
// The RandomizeKey method is deprecated:

// Generates and sets a random 32-byte (256-bit) secret key.
$crypt->RandomizeKey();

// ------------------------------------------------------------------------
// Do the equivalent using GenRandomBytesENC followed by SetEncodedKey

$crypt->put_EncodingMode('base64');
$randomKeyBase64 = $crypt->genRandomBytesENC(32);
$crypt->SetEncodedKey($randomKeyBase64,'base64');
