My Account @ Box.net

Good news for those who are not registered to Crackmes.de ! :) Now you can download my stuffs from my box !

I have added an swf boxplorer ( box explorer ;) ) below my blog header. You can anonymously download my CrackMes, KeygenMes, their Source Codes and Solutions to other crackmes by me; and I'm not gonna charge you for that, LOL.

So, do check my box for new CrackMes, KeygenMes and Sols.

CrackMe #1 :: C++ :: Difficulty : 1

KeyGenMe Location : CrackMe #1 @ Crackmes.de
Solution Location : Solution by DoomsDay

So, here is my first CrackMe. It's coded in ANSI C++. Features :
(*) NOT Packed
(*) NOT Encrypted
(*) Nice Konsole look with Double Sided Arrow Animation.

The Rules :
(*) NO Patching
(*) NO Brute-forcing

The Tasks :
1. Simply find the "2" secret codes that would pass ALL the tests.
2. Reverse the complete algorithm for checking the code.
3. Write a descent tutorial.

IMPORTANT :: If you happen to find a numeric secret-code that passes Test#3 but is negative, e.g. -8, that won't be accepted. The solution by DoomsDay mentioned above considers -8 as a valid secret-code. But that's NOT acceptable. After receiving solution from DoomsDay, I checked my source code again and found that negative codes get accepted due to a problem with flushing the input.

IMPORTANT :: Explain in your solution, how you found "the" secret code that would pass Test #3. Tests #1, #2 are easy enough. NO BRUTE-FORCING.

Readers, if you solve this, please upload your solution to CrackMes.de.

My very first blog !!

This is my first ever experience in blogging. So, welcome to my first blog.

Why did I start this blog ?
Haha, nothing special. I got myself registered at www.crackmes.de on 5th March 2009, (yeah recently !). I saw some of the blogs by andrewl.us (RCE Junk blog), obnoxious (obnoxious coder blog) and I was inspired to start one of my own. That's it and here am I -- blogging.

What am I going to blog about ?
I will be mainly blogging about CRACKING (as the title says). I will be discussing about my CrackMes / KeyGenMes submitted to www.crackmes.de. I would discuss about the specialty of each of my work. I would discuss about the solutions to my works. [[ Suggestions by readers are most welcome ]]

I may not be able to maintain the blog regularly because of a wide-range of causes (workload, studies ...). So, just bear with it. ;)

So,.. I guess that was enough introduction. Next post, I will start with my KeyGenMes...
