(PHP ActiveX) Transition from RandomizeKey to GenRandomBytesENC

Provides instructions for replacing deprecated RandomizeKey method calls with GenRandomBytesENC.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

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

$crypt->CryptAlgorithm = 'aes';
$crypt->CipherMode = 'cbc';
$crypt->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->EncodingMode = 'base64';
$randomKeyBase64 = $crypt->genRandomBytesENC(32);
$crypt->SetEncodedKey($randomKeyBase64,'base64');
