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 vb.net.

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:

			serial = "WDW21" + (name.Length + 2222).ToString() + "-";
			for(int i=0;i<name.Length;i++)
				serial += String.Format("{0:X}",Convert.ToByte(name[i]));

[Keygenme] Levis’s SImple Keygenme05

Hello all mates,
This keygen i created today, just for fun, and for who want to test their reversing skills. It’s an easy one ( as i said in the title, very simple :D), so feel free to defeat it.

Name :Levis’s Simple Keygenme05
Language: Borland Delphi
Packer : N/A
Level : Tell me?
PlAyInG rUlEz: Only keygen accepted, serial fishing is okay, but will not be valid solution. and, of course , no patching at all 🙂

All bug reports are welcome
Enjoy and best regards,

Keygen for NB_RCE Keygenme#2 (source code included)

Hello all mates,

This is my keygen for NB_RCE’s Keygenme#2. Too lazy to make a tutorial about it, just look into my code(Delphi) included in the archive, you will understand the algorithm.
Name : NB_RCE Keygenme#2
Language : Borland Delphi
Packer: N/A
Protection: MD5(modified init vectors) + Custom algorithm
Solution: Keygen (Delphi source included).
Made by : Levis/REPT
This keygenme has a very interesting algorithm(in my opinion). And you need to trace carefully, to make a valid keygen for it. However, it’s easy enough for you to give it a try.
Thank NB_RCE for sharing this keygenme.
