This is an example of a generator and checker program for license keys. It makes all alphabetic keys (6 groups of 5 letters). What is different about this is I paid attention to some documentation on the technology of how "good" serial keys work. In order to generate a key, you load the generator and type in some customers private and personal info like their name and the date/time of purchase or something, or a customer ID and their name or what ever. So, it uses this unique information and hashes it. Cryptographic process' are done to each character of that initial seed data to create the majority of the key. Then the seed value and the remaining key parts are salt hashed and the first 4 characters of that hash are placed at the end of the code. Then it is broken up into sections using a "-" symbol, eg: IKCFG-HFSIO-HYBYH-OADHJ-INGVC-DDOBB The benefit of a system like this is that you don't need to include any license keys with the product, or have lists of anything to check against. The product on the users end checks only certain aspects of the key (so hackers would not be able to make a global hacked keygen for all future versions because you can just alter which sections of the key a new program check and then everyones old keys still work and the keygen fails) and both checks the hash of the seed and key sections to make sure the checksum matches up with the end of the key AND if someone figured that out and made a random key and made a valid checksum thinking that would be enough, the software realises this and warns you that it was a fabricated key. Currently all the checker does is notify with message boxes but I can now use this template in the future to make a good and solid serial key protection on something. You will never prevent everything in the world though, I am sure if hackers can crack actually "programmed" software that they could crack autoit in a trivial amount of time and just remove protections depending on how much time you put into obfuscating your code. That being said I think this is pretty cool, secure and convenient since the codes are checked in isolation on the client's PC for validity without needing lists of codes disguised on their computer or anything. It all adds to the security. Checker just checks and lets you know the status of the key, the generator will copy the individuals code to clipboard after you type in the "customers" details for seed information and click the button. Just paste it in a notepad and you have it then for testing the checker. For each unique "product" you would want all new random values on both the checker and generator where the hash salt is eg $ks[3] = 'NUB%F$Wt6j9' They must be the same on both generator and checker and unique to each program, same with the 'Test program v1.000' string which is salt for the over all checksum part of the code. Any way, if you want to have a look, here are the files, I welcome any feedback on this design. Serial Code GeneratorF Final Working!V3.au3 Serial Code CheckerFWorking!V3.au3

compact21, You can find all available archive material here. But why cripple yourself with such an old (released 24th December, 2008) version? What is wrong with the current release? M23

I see 2 issues here. First off, if hit Alt+0, it'll start itself into a loop because Send will trigger HotKeySet again, and again, and again. Secondly, there's an extra comma after $key which is causing an error. If we completely remove the line containing the send function: HotKeySet("!0", "MyHotkeyHandler") While 1 Sleep(100) WEnd Func MyHotkeyHandler() $key = @HotKeyPressed MsgBox(0,"","Inside Function") EndFunc The code works and displays the message box.
