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 page.

Chilkat Module for Perl 5.8.*

Chilkat Module for Perl 5.10.*

Chilkat Module for Perl 5.8.* (x64)

Chilkat Module for Perl 5.10.* (x64)

use chilkat;

$crypt = new chilkat::CkCrypt2();

$success = $crypt->UnlockComponent("Anything for 30-day trial");
if ($success != 1) {
    print "Crypt component unlock failed" . "\n";
    exit;
}

#  Use "blowfish2" to get proper results:
$crypt->put_CryptAlgorithm("blowfish2");

#  CipherMode may be "ecb" or "cbc"
$crypt->put_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->put_KeyLength(256);

#  Pad with NULL bytes (PHP pads with NULL bytes)
$crypt->put_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->put_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:
#  276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

#  Do 128-bit Blowfish encryption:
$crypt->put_KeyLength(128);
$keyAscii = "1234567890123456";
$crypt->SetEncodedKey($keyAscii,"ascii");

$cipherText = $crypt->encryptStringENC($plainText);
print $cipherText . "\n";
#  Output should be:
#  d2b5abb73208aea3790621d028afcc74d8dd65fb9ea8e666444a72523f5ecca60df79a424e2c714fa6efbafcc40bdca0
