Please help me with this small app for XOR

Can anyone make a prog that creates more keys
similar to this one by using XOR 88 ???

Is there anyone out there that can show me how?
Give an examle app or source for creating such a ke as the above!

Are you trying to crack a program?

here:

VB Code:

for y = 0 to 3
for x = 0 to 4
rs = rs & hex(15*rnd)
next
rs = rs & " "
next

I was trying to learn ASM (assembler) and i was now running
a program STEP by STEP by using W32DSM (v8.9)
But then i came across the "Register Now" NAG screen
and wanted to REMOVE that so i cuold use it as TRIAL ware
but with no NAG screen...

I know that it also writes to the register (the SERIAL CODE)
but i don't care about that now..
What i wanted to do was EXTRACT the prossess that
checks the SERIAL that you input...

So that i could build an KEY MAKER.
or a PATCH to remove the NAG screen

THE PROGRAM IM TRYING ON IS:
----------------------------------------
Windguides Tweak Manager 2.0

----------------------------------------

And the code:
1AC78 23D1B 83EAD A21B9 works well, but i wanna make more codes...Is that possible..for y = 0 to 3

PS: by the way..

Code:

---

for x = 0 to 4
rs = rs & hex(15*rnd)
next
rs = rs & " "
next

---

Doesn't make any working code's ... (but it produces HEX strings similar to the one above,but non-woking ones)

Lol.

Lamer.

Had to learn some coding first !!

But i don't know cracking yet...

So can you crack it then??
Download and crack it.... Then learn me how you did it...

Or find out whats wrong with the code you provided...
I mean, why it wont register... with the new codes..

--Then you can try to figure out how i found the working code--

hehe.. Im a lamer and im proud of it....

PS: here is a small simple keymaker....
