Linux Patching Helper – Source Code download

Hello all mates,

This is my small tool coded in Free Pascal/Lazarus for Linux Platform, that i’ve made a demonstration video before, you can view it here. I planned to make it public long time ago, but due to some issues in code makes it become non-stable. Nothing special, just some dummy lines of code, and now i fixed (a bit) about memory consumption when displaying the result in memobox. Changed from TMemo to TSynMemo and added a timer to avoid the delay. Take a look at this screenshot:

I captured that picture on my Arch KDE desktop, and the project was built using Qt (Created by Lazarus-qt version0. In order to make it working properly, we MUST HAVE binutils installed (which contains objdump – the most important tool)

The source code is a archive of whole my Lazarus Project. Just download the archive, extract and open project in Lazarus, and then compile it. It’s ready to use :). And if you don’t know how to use, just watch my demonstration video (link above).

Update: Source code now available at github you can grab the source with bash commands;

 cd ~/
git clone git://

Enjoy and best regards,


A cheap, (and) simple keygen for a memorable time

Hello all mates,

Just walking around the internet, and i found this site:

which has a small utility named “Windriver Ghost”. That makes me remember the first day when i came into the Reverse Engineering World. I did a keygen for it when i was a young boyt (13,14 years old). Haha, it’s very joyful and i’m so happy that time. It was my first keygen, coded in

And now, many years passed, today i analyzed it again and see no change in this software. Still the same algorithm and i decided to make a keygen for it (again), for fun :).

There are no explain words on analyzing and coding, just post the raw code here (in C#), for who interested. This is keygen for Enterprise Version or Windriver Ghost:

			string name = Console.ReadLine();
			string output,serial=null;
			if(name.Length ==0)
				output = "Your name is not valid! Chosse another!";
				Gen_key(name,ref serial);
				output = "Your serial is: " + serial;
		public static void Gen_key(string name, ref string serial)
			serial = "WDW21" + (name.Length + 2222).ToString() + "-";
			for(int i=0;i<name.Length;i++)
				serial += String.Format("{0:X}",Convert.ToByte(name[i]));
