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.

LOCAL loCrypt
LOCAL lnSuccess
LOCAL lcIvAscii
LOCAL lcKeyAscii
LOCAL lcPlainText
LOCAL lcCipherText

loCrypt = CreateObject('Chilkat.Crypt2')

lnSuccess = loCrypt.UnlockComponent("Anything for 30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX("Crypt component unlock failed")
    QUIT
ENDIF

*  Use "blowfish2" to get proper results:
loCrypt.CryptAlgorithm = "blowfish2"

*  CipherMode may be "ecb" or "cbc"
loCrypt.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.
loCrypt.KeyLength = 256

*  Pad with NULL bytes (PHP pads with NULL bytes)
loCrypt.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".
loCrypt.EncodingMode = "hex"

*  The blowfish algorithm uses a 64-bit block size,
*  therefore the IV must be 8 bytes:

lcIvAscii = "12345678"
loCrypt.SetEncodedIV(lcIvAscii,"ascii")

*  For 256-bit encryption, the key is 32 bytes:

lcKeyAscii = "1234567890123456ABCDEFGHIJKLMNOP"
loCrypt.SetEncodedKey(lcKeyAscii,"ascii")

lcPlainText = "The quick brown fox jumped over the lazy dog"

lcCipherText = loCrypt.EncryptStringENC(lcPlainText)
=MESSAGEBOX(lcCipherText)
*  Output should be:
*  276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

*  Do 128-bit Blowfish encryption:
loCrypt.KeyLength = 128
lcKeyAscii = "1234567890123456"
loCrypt.SetEncodedKey(lcKeyAscii,"ascii")

lcCipherText = loCrypt.EncryptStringENC(lcPlainText)
=MESSAGEBOX(lcCipherText)
*  Output should be:
*  d2b5abb73208aea3790621d028afcc74d8dd65fb9ea8e666444a72523f5ecca60df79a424e2c714fa6efbafcc40bdca0
