(PHP ActiveX) Blowfish Encryption to Match PHP's Mcrypt Extension

Demonstrates how to match Blowfish encryption results with PHP's mcrypt extension.

Please refer to this PHP (non-Chilkat) example for PHP Blowfish Encryption. The code here matches the PHP mcrypt results on that web page.

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

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");

// Use "blowfish2" to get proper results:
$crypt->CryptAlgorithm = 'blowfish2';

// CipherMode may be "ecb" or "cbc"
$crypt->CipherMode = 'cbc';

// KeyLength (in bits) may be a number between 32 and 448.
// 128-bits is usually sufficient.  The KeyLength must be a 
// multiple of 8.
$crypt->KeyLength = 256;

// Pad with NULL bytes (PHP pads with NULL bytes)
$crypt->PaddingScheme = 3;

// EncodingMode specifies the encoding of the output for
// encryption, and the input for decryption.
// It may be "hex", "url", "base64", or "quoted-printable".
$crypt->EncodingMode = 'hex';

// The blowfish algorithm uses a 64-bit block size, 
// therefore the IV must be 8 bytes:
$ivAscii = '12345678';
$crypt->SetEncodedIV($ivAscii,'ascii');

// For 256-bit encryption, the key is 32 bytes:
$keyAscii = '1234567890123456ABCDEFGHIJKLMNOP';
$crypt->SetEncodedKey($keyAscii,'ascii');

$plainText = 'The quick brown fox jumped over the lazy dog';

$cipherText = $crypt->encryptStringENC($plainText);
print $cipherText . "\n";
// Output should be (case insensitive):
// 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

// Do 128-bit Blowfish encryption:
$crypt->KeyLength = 128;
$keyAscii = '1234567890123456';
$crypt->SetEncodedKey($keyAscii,'ascii');

$cipherText = $crypt->encryptStringENC($plainText);
print $cipherText . "\n";
// Output should be (case insensitive):
// d2b5abb73208aea3790621d028afcc74d8dd65fb9ea8e666444a72523f5ecca60df79a424e2c714fa6efbafcc40bdca
