(AutoIt) Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

Demonstrates how to compute:

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

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

Local $sPassword = "secret"

$oCrypt = ObjCreate("Chilkat.Crypt2")
$oCrypt.HashAlgorithm = "SHA-1"
$oCrypt.EncodingMode = "base64"

; Generate a 16-byte random nonce
$oPrng = ObjCreate("Chilkat.Prng")
$oBd = ObjCreate("Chilkat.BinData")
$oPrng.GenRandomBd(16,$oBd)

; Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
$oDt = ObjCreate("Chilkat.CkDateTime")
$oDt.SetFromCurrentSystemTime()
Local $sCreated = $oDt.GetAsTimestamp(False)
$oBd.AppendString($sCreated,"utf-8")

; This example wishes to calculate a password digest like this:
; Password_Digest = Base64 ( SHA-1 ( nonce + created + SHA-1(password) ) )

; First SHA-1 digest the password...
Local $sPasswordSha1 = $oCrypt.HashStringENC($sPassword)
; Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
$oBd.AppendEncoded($sPasswordSha1,"base64")

Local $sPasswordDigest = $oCrypt.HashBdENC($oBd)
