Replacing keys for a Cryptochat program

[Fluffet]

Hello, everyone. I am trying to create a "Cryptochat" program, if you will, but I really dont know where to begin. I am new to AutoIt and programming, and I've only made spambots and such by using Send and a couple of vars that used InputBoxes. You could safely say my skills are limited .

Anyway, my idea is this:

I want a script that is silently running in the background until I press F12. I want it to be a "toggle" button (I have no idea how to make one), that when pressed, changes some of the keyboard buttons to something else so you can type stuff that looks like random letters but really isn't. The thing is, I dont want the script to turn off after you've pressed it, I want it to "hibernate" all the time until I turn it off manually so I can just use F12 to chat crypted and F12 to chat normally.

I hope you get the idea. To make it more clear to you, I've made a small chart (this is just the start)

A - T
B - S
C - R
D - Z
E - U
F - Q

When I press A on my keyboard, a T is Sent. B on keyboard and S is sent, etc etc. So if I want to write the text "ABC" to my friend, I would actually send the letters "TSR" to him, but I will have pressed "ABC" on my keyboard. The only way I know with my limited skillset to make this is by using HotKeySet commands all over, and I suppose that is the easiest way.

Now, at the other end, of course, I'll need a Decrypter, but that is probably easy to make once I know how to make the one that swaps all the letters first. If you have time, please point me some tips there too. I want the decrypter to be nothing more complicated than an Inputbox where you paste whatever's been written and the decrypted text comes up in a MsgBox.

Help is greatly appreciated. I want to chat with specific people in public chatrooms without anyone noticing .

Here is a little example of how you might use hotkeys to do it, just using the "a" key

$On = False
HotKeySet("{PAUSE}","toggle")
HotKeySet("a", "a")

While 1
    Sleep(10)
WEnd

Func toggle()
    $On = Not $On
EndFunc

Func a()
    If $On Then
        Send("t")
        Return
    EndIf
    HotKeySet("a") ; you need to disable the hotkey to avoid an infinate loop
    Send("a")
    HotKeySet("a", "a")
EndFunc   ;==>a

Fluffet,

You face a dilemma here. What you want to do is perfectly feasible, but telling you how to do it would break the forum rules as it would effctively be a keylogger which is one of the few no-nos around here.

So what I suggest is that you do is use the same idea you had for a decrypter:

- Press a HotKey to bring up a small GUI with an edit control and a button.

- Type what you want to send into the edit.

- On a press of the button, the text is encrypted in some manner and then sent to the app, while the GUI disappears until next time.

If you choose a suitable encryption algorithm, you can use the same one for both encryption and decryption.

But as WikiLeaks has shown today, do not expect anything you say to remain secret for ever!

Give it ago and see how you get on - you know w here we are if you run into problems.
