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.

LOCAL oCrypt
LOCAL cIvAscii
LOCAL cKeyAscii
LOCAL cPlainText
LOCAL cCipherText

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

oCrypt := CreateObject("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:
cIvAscii := "12345678"
oCrypt:SetEncodedIV(cIvAscii, "ascii")

//  For 256-bit encryption, the key is 32 bytes:
cKeyAscii := "1234567890123456ABCDEFGHIJKLMNOP"
oCrypt:SetEncodedKey(cKeyAscii, "ascii")

cPlainText := "The quick brown fox jumped over the lazy dog"

cCipherText := oCrypt:EncryptStringENC(cPlainText)
? cCipherText
//  Output should be (case insensitive):
//  276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

//  Do 128-bit Blowfish encryption:
oCrypt:KeyLength := 128
cKeyAscii := "1234567890123456"
oCrypt:SetEncodedKey(cKeyAscii, "ascii")

cCipherText := oCrypt:EncryptStringENC(cPlainText)
