$oCrypt = ObjCreate("Chilkat.Crypt2")

Local $sHexKey
; http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf

Local $sPw = "password"
Local $sPwCharset = "ansi"
; Hash algorithms may be: sha1, md2, md5, etc.
Local $sHashAlg = "sha1"
; The salt should be 8 bytes:
Local $saltHex = "78578E5A5D63CB06"
Local $iterationCount = 2048
; Derive a 192-bit key from the password.
Local $iOutputBitLen = 192

; The derived key is returned as a hex or base64 encoded string.
; (Note: The salt argument must be a string that also uses
; the same encoding.)
Local $sEnc = "hex"

$sHexKey = $oCrypt.Pbkdf2($sPw,$sPwCharset,$sHashAlg,$saltHex,$iterationCount,$iOutputBitLen,$sEnc)

ConsoleWrite($sHexKey & @CRLF)

; The output should have this value:
