[RELEASE]Encrypted login strore without file

hi,

inspired by the recent discussion in which I was criticized, I rewrote the code for saving login data making significant changes.
In this new version of login files are not used for data storage, at frist use two keys are created randomly and stored in the system registry these are used to crypt the login data which are also saved in system registry

Note: for right work need to use lib in the attachment. All is tested on Win7 32/64 bit
Who want to discuss other work can create a discussion without make flame here thanks.

Code:

import os
import sys
import string
from _winreg import *

	def __OnClickSaveButton(self):	
		id = self.idEditLine.GetText()
		pwd = self.pwdEditLine.GetText()
		self.__SaveAccountInfo(id, pwd)

	def __SaveAccountInfo(self, user, passw):
		try:
			userid = self.__encrypt(user).replace(' ', '-')
			passwd = self.__encrypt(passw).replace(' ', '-')
			aReg = ConnectRegistry(None, HKEY_CURRENT_USER)
			aKey = CreateKey(aReg, "software\\MyClientName\\")
			SetValueEx(aKey, "user", 0, REG_SZ, userid)
			SetValueEx(aKey, "pass", 0, REG_SZ, passwd)
			CloseKey(aKey)
			CloseKey(aReg)
			self.PopupNotifyMessage("Info: Dati di Login salvati.")
		except:
			self.PopupNotifyMessage("Info: Errore Salvataggio dati di Login.")
			return

	def __LoadAccountInfo(self):
		try:
			login_data = os.popen('reg QUERY "HKEY_CURRENT_USER\software\MyClientName" /v user').readlines()
			login_line = login_data[2].split()
			login_value = login_line[2].replace('-', ' ').strip('\n')
			passw_data = os.popen('reg QUERY "HKEY_CURRENT_USER\software\MyClientName" /v pass').readlines()
			passw_line = passw_data[2].split()
			passw_value = passw_line[2].replace('-', ' ').strip('\n')
			
			user=self.__decrypt(login_value)
			passw=self.__decrypt(passw_value)
				
			return user, passw

		except:

			return -1, -1

				key2_value = app.GetRandom(1,32768)
				aKey = CreateKey(aReg, "software\\MyClientName\\")
				SetValueEx(aKey, "key1", 0, REG_DWORD, key1_value)
				SetValueEx(aKey, "key2", 0, REG_DWORD, key2_value)
				CloseKey(aKey)
				CloseKey(aReg)
			except:
				CloseKey(aReg)
				return
				
		key1_data = os.popen('reg QUERY "HKEY_CURRENT_USER\software\MyClientName" /v key1').readlines()

		key1_value = int(key1_line[2], 16)
		key2_data = os.popen('reg QUERY "HKEY_CURRENT_USER\software\MyClientName" /v key2').readlines()
		key2_line = key2_data[2].split()
		key2_value = int(key2_line[2], 16)
		
		a = string
		new_string = ''
		for x in a:
			new_string = new_string+str(int(ord(x) + key1_value) * key2_value)+' '
			
		return new_string
		
	def __decrypt(self, string):
		aReg = ConnectRegistry(None, HKEY_CURRENT_USER)
		try:
			aKey = OpenKey(aReg, "software\\MyClientName\\")
		except WindowsError:
			CloseKey(aReg)
			return
			
		CloseKey(aKey)
		CloseKey(aReg)
		key1_data = os.popen('reg QUERY "HKEY_CURRENT_USER\software\MyClientName" /v key1').readlines()

		a = string
		new_string = ''
		b = a.split()
		for x in b:
			new_string = new_string+chr((int(x) / key2_value) - key1_value)
			
		return new_string
