(PowerBuilder) 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

integer li_rc
oleobject loo_Crypt
string ls_IvAscii
string ls_KeyAscii
string ls_PlainText
string ls_CipherText

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

loo_Crypt = create oleobject
// Use "Chilkat_9_5_0.Crypt2" for versions of Chilkat < 10.0.0
li_rc = loo_Crypt.ConnectToNewObject("Chilkat.Crypt2")
if li_rc < 0 then
    destroy loo_Crypt
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// Use "blowfish2" to get proper results:
loo_Crypt.CryptAlgorithm = "blowfish2"

// CipherMode may be "ecb" or "cbc"
loo_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.
loo_Crypt.KeyLength = 256

// Pad with NULL bytes (PHP pads with NULL bytes)
loo_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".
loo_Crypt.EncodingMode = "hex"

// The blowfish algorithm uses a 64-bit block size, 
// therefore the IV must be 8 bytes:
ls_IvAscii = "12345678"
loo_Crypt.SetEncodedIV(ls_IvAscii,"ascii")

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

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

ls_CipherText = loo_Crypt.EncryptStringENC(ls_PlainText)
Write-Debug ls_CipherText
// Output should be (case insensitive):
// 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

// Do 128-bit Blowfish encryption:
loo_Crypt.KeyLength = 128
ls_KeyAscii = "1234567890123456"
loo_Crypt.SetEncodedKey(ls_KeyAscii,"ascii")

ls_CipherText = loo_Crypt.EncryptStringENC(ls_PlainText)
Write-Debug ls_CipherText
// Output should be (case insensitive):
