Hi,

here's level 2: KeygenMe__hASSh__2_.rar

Fishing/Selfkeygenning/loveing : 0 points

Ripping : 1 point

Recognizing&Owning : 1337 pointz

If you're after 0 or 1 point, it's easy like ****. Again nothing protected or hidden.

Just a naked row of instructions. But if you're after the full win, this one might be a small bitch.. dunno.

Have phun :happy:

Cracked.

It was fun =D

KeyGen.zip

A selfkeygen (0 points.. cough) with one JNZ to JMP and some NOPs... ok.

But why this weird overlay :? Trying to hide what ? ^^

If your overlay saves it to C:\ packed with FSG, then you shouldn't at least forget to

delete it afterwards. Or maybe better save it to TEMP folder..

Oh... lol i was seeing if you would notice if it was a keygen or Self-Keygen xD i packed it with FSG and used D1S1G to make it look like UPX

idk what D1S1G does.... i guess it extracts to C:\ then o.o?

I hope this is worth atleast 1 point......

My head hurts now....

Ofc

But your code really made me wonder. For example you got some lstrcat in there and other

weird stuff.. nearly looked like obfuscation to me :?

The trick is to get a hasher which does them all. I got 2 hash functions in there.

The 2nd is CRC16 - PEiD might have told you. So I got 2 main hash calls.. each with

some parameters: ptrInput, ptrOutput and 1 or more init values.

Maybe it was mean not to use usual inits. So you would first need to look up, what

the inits might 'usually' be and try a call with such init. After that compare the output string

with the outputs of a hasher to recognize the type of hash...

I don't want to name the 1st hash, yet.. but for both calls I only changed 1 BIT in the inits

I have no idea what the first hash is, I couldnt ever figure it out. I ripped the one out of the keygenme and used the lstrcat to set up the buffer.......Im sure it would have been easier if I could have figured out the first hash..........so I made the best of it.........oh well I tried....

Had a busy weekend but hoping to take a look at this early next week

Hoping I dont get owned by this one

You're going to have to put me out of my misery on this one mate

Easily rippable of course, but I'm really not sure what that other hash is. :s

Oh goody something to keep me occupied on the weekend.. no solutions yet please

UFO told me what the hash is.... for all those as confused as I was, it isnt some 'completely' obscure hash. It is however, not one of the more commmonly implemented one.

Good luck syk071c

I wanna know! PM please

(i wont make a keygen, i just wanna know!)

Glad I wasn't alone in getting frustrated with that one. Sent you a PM to put you out of your misery

Well I don't feel half as bad now for having a hard time with this............Would some one care to enlighten me ?

Besides hashing the algo is simple and easy to own.

Whats hashing conserned; it needs time to trace it and understand it; i just dont have time for it at the time being.

nice crackme, UFO!

BR, ChupaChu!
