2-Key Triple DES (112 bits)

See more Encryption Examples

Demonstrates 2-Key Triple DES encryption (112-bit 3DES encryption). AutoIt

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

$oCrypt = ObjCreate("Chilkat.Crypt2")

; Specify 3DES for the encryption algorithm:
$oCrypt.CryptAlgorithm = "3des"

$oCrypt.CipherMode = "ecb"

; For 2-Key Triple-DES, use a key length of 128
; (Given that each byte's msb is a parity bit, the strength is really 112 bits).
$oCrypt.KeyLength = 128

; Pad with zeros
$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"

; Let's create a secret key by using the MD5 hash of a password.
; The Digest-MD5 algorithm produces a 16-byte hash (i.e. 128 bits)
$oCrypt.HashAlgorithm = "md5"
Local $sKeyHex = $oCrypt.HashStringENC("secretPassword")

; Set the encryption key:
$oCrypt.SetEncodedKey $sKeyHex,"hex"

; Encrypt
Local $sEncStr = $oCrypt.EncryptStringENC("The quick brown fox jumped over the lazy dog")
ConsoleWrite($sEncStr & @CRLF)

; Now decrypt:
Local $sDecStr = $oCrypt.DecryptStringENC($sEncStr)
ConsoleWrite($sDecStr & @CRLF)
