HashPassword.au3

An AutoIt UDF to salt, hash and check passwords.

Installation

Copy the file HashPassword.au3 to the directory of your script.

Usage

#include "HashPassword.au3"
Local $Password = InputBox("HashPassword", "Enter the password to hash", "", "*")
Local $Hash = _HashPassword($Password)
MsgBox(0, "HashPassword", "The Hash: " & $Hash)
Local $RePassword = InputBox("HashPassword", "Enter the password to check it against the hash", "", "*")
If _CheckPassword($RePassword, $Hash) = True Then
    MsgBox(0, "HashPassword", "Password is correct!")
Else
    MsgBox(0, "HashPassword", "Password is not correct!")
EndIf

How it works

A random string (the salt) will be added to the password: SecretPasswordr5sa3MJL65WbS2Y0qx43S1IW9PnIj2d43awK1Y3Q
This new string will be hashed with SHA512 hash algorythm 256 times.
The resulting hash and the used salt is returned as one string seperated by $.
