Blowfish Encryption to Match PHP's Mcrypt Extension

See more Encryption Examples

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.

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

$oCrypt = ObjCreate("Chilkat.Crypt2")

; Use "blowfish2" to get proper results:
$oCrypt.CryptAlgorithm = "blowfish2"

; CipherMode may be "ecb" or "cbc"
$oCrypt.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.
$oCrypt.KeyLength = 256

; Pad with NULL bytes (PHP pads with NULL bytes)
$oCrypt.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".
$oCrypt.EncodingMode = "hex"

; The blowfish algorithm uses a 64-bit block size, 
; therefore the IV must be 8 bytes:
Local $sIvAscii = "12345678"
$oCrypt.SetEncodedIV $sIvAscii,"ascii"

; For 256-bit encryption, the key is 32 bytes:
Local $sKeyAscii = "1234567890123456ABCDEFGHIJKLMNOP"
$oCrypt.SetEncodedKey $sKeyAscii,"ascii"

Local $sPlainText
$sPlainText = "The quick brown fox jumped over the lazy dog"

Local $sCipherText = $oCrypt.EncryptStringENC($sPlainText)
ConsoleWrite($sCipherText & @CRLF)
; Output should be (case insensitive):
; 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

; Do 128-bit Blowfish encryption:
$oCrypt.KeyLength = 128
$sKeyAscii = "1234567890123456"
$oCrypt.SetEncodedKey $sKeyAscii,"ascii"

$sCipherText = $oCrypt.EncryptStringENC($sPlainText)
ConsoleWrite($sCipherText & @CRLF)
; Output should be (case insensitive):
