(Solved) What am I doing wrong with Crypt.au3?

6 posts in this topic

#1 ·  Posted (edited)

I am trying to encrypt and decrypt data a user inputs into a input box using crypt.au3 functions.  However, when this is actually run, it returns all "0"s.  Can someone please tell me what I am doing wrong?

Global Const $key = _Crypt_DeriveKey ( "KeyToKeepDataSafe", $CALG_AES_256 )
    #Region --- CodeWizard generated code Start ---
    ;InputBox features: Title=Yes, Prompt=Yes, Default Text=No, Mandatory
    If Not IsDeclared("sInputBoxAnswer") Then Local $sInputBoxAnswer
    $sInputBoxAnswer = InputBox("Name", "Please enter your first and last name.", "", " M")
    Select
        Case @error = 0
            $Namearray = StringSplit($sInputBoxAnswer, " ")
            If $Namearray[0] = 2 And $Namearray[2] <> "" Then
                IniWrite($storepath, "Name", "First", encry ($Namearray[1]))
                IniWrite($storepath, "Name", "Last", encry ($Namearray[2]))
                #Region --- CodeWizard generated code Start ---
;MsgBox features: Title=Yes, Text=Yes, Buttons=OK, Icon=None
MsgBox(0,"data","Encrypt 1: " & encry ($Namearray[1]) & @CRLF & "Encrypt 2: " & encry ($Namearray[2]) & @CRLF & "Decrypt 1: " & decry ( IniRead ( $storepath, "Name", "First", "na" ) ) & @CRLF & "Decrypt 2: " & decry ( IniRead ( $storepath, "Name", "Last", "na" ) ))
#EndRegion --- CodeWizard generated code End ---

            Else
                #Region --- CodeWizard generated code Start ---

                ;MsgBox features: Title=Yes, Text=Yes, Buttons=Yes and No, Icon=Critical
                If Not IsDeclared("iMsgBoxAnswer") Then Local $iMsgBoxAnswer
                $iMsgBoxAnswer = MsgBox($MB_YESNO + $MB_ICONHAND, "an error occured", "Did you put input your full name separated by space?  Do you want to try again?")
                Select
                    Case $iMsgBoxAnswer = $IDYES
                        names(True)
                    Case $iMsgBoxAnswer = $IDNO
                        $errr = True
                EndSelect
                #EndRegion --- CodeWizard generated code Start ---
            EndIf

        Case @error = 1 ;The Cancel button was pushed
            $errr = True
        Case @error = 3 ;The InputBox failed to open
            $errr = True
    EndSelect
    #EndRegion --- CodeWizard generated code Start ---
    Func encry ( $input2 )
    _Crypt_Startup ()
    _Crypt_EncryptData ( $input2, $key, $CALG_USERKEY )
    _Crypt_Shutdown()
EndFunc
Func decry ( $input )
    _Crypt_Startup ( )
    _Crypt_DecryptData ( $input, $key, $CALG_USERKEY )
    _Crypt_Shutdown ()
EndFunc

Just be aware that this is a small snippet out of a massive project I am working on.  Everything compile correctly (I do have "#include <Crypt.au3>" in the code, just didn't put in snippet), so I am guessing the problem lies in the area I shared

You just forgot to return the result:

Func encry($input2)
    _Crypt_Startup()
    Local $sRet=_Crypt_EncryptData($input2, $key, $CALG_USERKEY)
    _Crypt_Shutdown()
    Return $sRet
EndFunc   ;==>encry

there are also other errors, forgot to include:

#include <Crypt.au3>
#include <MsgBoxConstants.au3>

and here the rest errors:

so i haven't tested.

Thank you.  That certainly did help with getting "0"s as the return.  Can't believe I forgot about the return.  But like I said, this is a small snippet of a big project.  Everything compiles and there are no errors, even if i didn't put all of the code.  But on to the new issue.  The decrypt function is not returning the original string typed into the input box like it should.  I think the IniRead function is returning "na" based on the length of the string returned (which is still encrypted for some reason).  So if the IniRead function was reading "na", both decry returns should be the same value.  I'm stumped.  Any ideas?  Code is same as original post with the exception of the return statements added to the encry and decry functions.
