AutoIt Snippets

Welcome To The AutoIt Snippets Page - ( Snippet - A short reusable piece of computer code ).

Snippets are generally single functions or small pieces of AutoIt code that can be included into a script which give extra functionality. This will cover a wide variety of subjects and uses. Examples include anything from finding if an internet connection is working or possibly the date Windows was installed. This page is intended to give easy access to the functions.

Please always credit an author in your script if you use their code. It is only polite.

_PasswordCrypt

Author: Valuater

Modified: guinness

#include <Crypt.au3>

Local $sGenericPassword_1 = 'Password@AutoIt', $sGenericPassword_2 = 'NewPassword@AutoIt', $sSavePath = @ScriptDir & '\License.dat'
ConsoleWrite('1. ' & _PasswordCrypt($sGenericPassword_1, $sSavePath) & @CRLF) ; Write the password to a file located in the @ScriptDir. The password we wrote is returned by the function.
ConsoleWrite('2. ' & _PasswordCrypt($sGenericPassword_1, $sSavePath) & @CRLF) ; Since the password has been written already, we now want to check if the user has entered the password correctly. Returns True or False.
ConsoleWrite('3. ' & _PasswordCrypt($sGenericPassword_2, $sSavePath, 1) & @CRLF) ; Overwrite the old password with a new one.
ConsoleWrite('4. ' & _PasswordCrypt($sGenericPassword_1, $sSavePath) & @CRLF) ; Check the password matches. This will fail as we're checking the old password against the new one.
FileDelete($sSavePath)

Func _PasswordCrypt($sPassword, $sFilePath, $iOverwrite = 0) ; By guinness, idea by Valuater.
    If FileExists($sFilePath) And $iOverwrite = 0 Then
        Return BinaryToString(_Crypt_DecryptData(IniRead($sFilePath, 'PasswordKey', 'Password', ''), @ComputerName, $CALG_AES_256)) == $sPassword
    Else
        If IniWrite($sFilePath, 'PasswordKey', 'Password', _Crypt_EncryptData($sPassword, @ComputerName, $CALG_AES_256)) Then
            Return $sPassword
        EndIf
    EndIf
    Return SetError(1, 0, '')
EndFunc   ;==>_PasswordCrypt
