Reversing .NET application

[rongchaua]

Its just not possible to break a RSA512 key with a good random generator generated on ur home computer.

It's true. I just forgot to say that my friend crack RSA Private Key with 4 Computers. .

@tkC: I'm waiting for your new tutorial for MaxToCode, too. Keep going. . BTW, I found a software protected by smartassembly. And your string decoder doesn't work with it. I have sent this software to UFO. When you want to take a look, I can also PM this software to you.

@zilot: Thanx for your answer.

Regards.

@rongchaua

I will try to complete the tutor on maxtocode soon, but don't depend on that coz it could take sometime, and regarding the smartassembly protected proggie ! maybe it's protected with ver 1.x which uses a different encoding algorithm to hide strings. i have the decoder for this one too if it's so needed.

@UFO

this is the full source code for the crackme for any one interesetd, with the License file maker code too.

OMFG... I'd never get the idea to look at the PM box, since I'm used to see a pop up win, when retrieving something. Sry... I didn't notice... I corrected it in the options now


Gotta read some other PMs, too, now dooh

Ya, as tKC mentioned, it's SmartAss 1.x !
His first SmartDecoder works perfectly on it:

Tested on it right now

What is that smartassed v 1.x software anyway ?

Don't pay attention to it. I have found that this software use this routine to protect.
1. Main Programm coded by .NET
2. Registration process is protected in .DLL. This DLL is native code and protected by ARMADILLO.

And what I do:
1. Use ArmaGUI to unpack it -> Registration goes away after unpacking. .

@tkC: Keep going with MaxToCode. .

@tKC:

Now I'm wondering, if kinda 'SmartKiller' is codable
...which patches any SmartTarget to be patchable furtheron

PS: What's planned next ?

What do u think about that sh!t ?

changes until now:
-drag&drop
-u can choose between 1.xx and 2.xx decoding
-I chose to display the listview while decoding,
coz if u already see, that it's decoding wrong,
u can abort decoding (about button changes into 'ABORT !')

-> so nothing really stunning, yet
but more functions to come (besides decoding)... well, I hope so

cheers

@ UFO

Please use filesend.net to upload ur files, pirateshare sux

Sry, I muddled 1.xx algo with 2.xx algo...
