I thought of adding a new section for helping without divulge everything because the board got spoilers! At this point a BIG thanks for the admins here on 0x00sec! They added the feature at the same day I asked for it! Unobfuscated: !W9ZmhISC!ngaxfHNOnleFnKBs_VH9jCL4dMZBLKLZqmnI_Rks6Ng Hints Obfuscated: !694nFRrB!bQKcK7Agu1MwuqBtyk_wRd-7KKCawruxZiTi-GBJejI Maybe a bit better knowledge of programming with C# if you worked with other languages you can of course also take python, etc (Would be interesting to see it in other languages too), but I think it can’t hurt to learn the language you are reversing DownloadĪs always I highly recomment to take the obfuscated version but it’s Ok to have a look at the unobfuscated one too. C# Reversing (Think I’ll remove this point in the next posts…)
LICENSE KEY GENERATOR ALGORITHM PASSWORD
KeyGens? Yep, this time you don’t have to find the password (Or a valid license in this case), but you should write a simple tool for finding valid ones.

It’s not a very complex one, so I think it’s a good start for keyGens.

Today we’ve got our first License algorithm (Yeah, everyone loves maths ). When we come to C++ this topic becomes interesting so you’ll see it then. Note: I also said to make a challenge about nag removing but I think I cancel this because it’s just too easy (Think of a program with a message box at start just remove the MessageBox() in code…).
LICENSE KEY GENERATOR ALGORITHM LICENSE KEY
As I said in my last post we’re coming to license key cracking.
