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.

PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

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

$crypt = New-Object Chilkat.Crypt2

# Use "blowfish2" to get proper results:
$crypt.CryptAlgorithm = "blowfish2"

# CipherMode may be "ecb" or "cbc"
$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.
$crypt.KeyLength = 256

# Pad with NULL bytes (PHP pads with NULL bytes)
$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".
$crypt.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)
$($cipherText)
# Output should be (case insensitive):
# 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

# Do 128-bit Blowfish encryption:
$crypt.KeyLength = 128
$keyAscii = "1234567890123456"
$crypt.SetEncodedKey($keyAscii,"ascii")

$cipherText = $crypt.EncryptStringENC($plainText)
$($cipherText)
# Output should be (case insensitive):
