Encryption Excel

[k66any]

Hi All

I am a newbie to the Autoit software and currently automating various web based system creations. I have a gui which writes to an excel file where the passwords are stored and would like to encript the passwords on the excel sheet to make it more secure if anyone managers to get access.

it also needs to decrypt the file on the gui to show the correct passwords, as this is very secure as it validates against the users LAN account. Your help is very much appreciated.

$Input1 = GUICtrlCreateInput("", 96, 16, 129, 21)

$Input2 = GUICtrlCreateInput("", 96, 48, 129, 21)

$Input10 = GUICtrlCreateInput("", 96, 80, 129, 21)

$i1 = 1

$AVATARID = _ExcelReadCell($oExcel, $i1, 2)

;MsgBox(1, "", ""& $AVATARID)

$i2 = 2

$AVATARDATE = _ExcelReadCell($oExcel, $i2, 2)

;MsgBox(1, "", ""& $AVATARDATE)

$i3 = 3

$AVATARPW = _ExcelReadCell($oExcel, $i3, 2)

;MsgBox(1, "", ""& $AVATARPW)

GUICtrlSetData($Input1,$AVATARID)

GUICtrlSetData($Input2,$AVATARPW)

GUICtrlSetData($Input10,$AVATARDATE)

func open()

$tester200=guiCTRLREAD($iNPUT1)

$tester201=guiCTRLREAD($iNPUT2)

$tester210=guiCTRLREAD($iNPUT10)

$ID_PW = @ScriptDir & "\PW.xlsx"

$oExcel = _ExcelBookOpen($ID_PW, $fVisible = 1);Create new book, make it visible

sleep(2000)

_ExcelWriteCell($oExcel, ($tester200), $i1, 2) ;Write to the Cell

_ExcelWriteCell($oExcel, ($tester201), $i3, 2) ;Write to the Cell

_ExcelWriteCell($oExcel, ($TESTER210), $i2, 2) ;Write to the Cell

MsgBox(0, "Exiting", "Press OK to Save File and Exit")

_ExcelBookSaveAs($oExcel,"\PW.xlsx") ; Now we save it into the temp directory; overwrite existing file if necessary

_ExcelBookClose($oExcel) ; And finally we close out

A fairly simple solution and the first that comes to mind is

You could do a stringreplace, substituting letters for numbers or letters for other letters when entering the data to the spread sheet, and then substitute back when reading from the sheet.
