Little problem with a Sentinel dongle...

[Dantes]

Hello gentlemen,

I am currently trying to get rid of a Sentinel dongle protection in a family of software available here:
http://www.autoship.com/downloads.htm

All the softs are controlled by the same installation disk, which decides if you're running them as demo, or as full products. If you install the softs without authorisation, they will automatically run as demos (of course... .

Those softs are VB6 Pcodes, with no code to do the dongle checking in them. Actually, everything is in a DLL included in the authorisation disk, called Aship300.dll.
This DLL imports functions from NSLMS324.DLL (the Sentinel code), and exports functions such as "AuthorizedToRun", "AuthorizedToContinue" and so on...

OK, so it seems that this is the place where everything happens. I'm no dongle expert, and I've spend quite some time trying to get a grasp on the protection scheme. And still no result.

If someone could have a look on this DLL code, and give me some hints about how the scheme works, that would be really nice.

Thanks a lot

PS: I attached the DLL, which is around 100K unzipped. So if you don't want to download the full thing, and just have a static look...

if "AuthorizedToRun" is something like :

cmp ...
jne ...
mov eax,1
...
xor eax,eax
ret

try to reverse the dll for anwser always positive, else
you can emulate the dongle response in the NSLMS324.DLL

for this task download the manual from sentinel site,
and see what the proggy want from those function.

i wonder if there are any dongles left which are not emulated by meteo..

meteo, will you be ever making a web page giving away these sources of your dongle emulators?

keep the cool work..

I could make it, but who give me normal hosting(without BSA intervence, without banners) . I could put all of my public code emulators of Sentinel, HASP, Hardlock, Novex, Wizzykey, Microguard and other...

i have fixed the problem for you on autoship and would be glad to show you exactly how i did that. presumably the fix would be similar on all their products. it is only a two bye fix and you are registered. i would need for you to verify the mechanics of your prog though, since i'm not familiar with its capablilities.

Hey MeteO e-mail me and I'll get you on my box, it's on a cable modem but I should have no problems hosting you and I have plenty of HD space.
