System save account problem

[BogdanGFX 0]

Hi guys, i have the next code 

	def __OnClickSaveLoginButton(self):
		id = self.idEditLine.GetText()
		pwd = self.pwdEditLine.GetText()
		if (len(id) == 0 or len(pwd) == 0):
			self.PopupNotifyMessage("ID and Password required.",self.SetIDEditLineFocus)
			return
		file_object  = open("account.cfg", "w")
		file_object.write(id+"\n"+pwd)
		self.PopupNotifyMessage("Account Saved.",self.SetIDEditLineFocus)
		file_object.close()

	def __OnClickLoadInfoButton(self):
		fileObject = open("account.cfg", "r").readlines()
		self.Connect(fileObject[0], fileObject[1])

Its for saving ID and Password to keep your account in the client, its triggered by buttons. And i want to make the saved password to be hashed in that file. I tried something but at login "Wrong ID / Pasword". Or if you know a system that works like this, please tell me. Maybe a system that works without a file. Thanks!
