; 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")
