2. #### Keygenning pDriLl CrackMe #2

Here is my tutorial for pDriLl's KeygenMe#2. It is using RSA, I hope it will be useful for you and of course this tutorial is not for complete newbies.

3. #### Keygenning Phoenix-Dev Shrink

This tutorial is for the experienced reverse engineer and not a beginners help. I'm not going deep into everything, but you should be able to follow my ideas. It took me some time to understand how this protection works and I had to invent some tricks to solve it. You might have to Google some topics like RSA or modular inverse to understand the math behind it. I'm also assuming, that you know how to use the tools that I'm going to use.

I hope you learn something from this tutorial and who knows, I can get you interested in iPhone reversing.

8. #### Keygenning Using the Z3 SMT Solver

Quoting Wikipedia, In computer science and mathematical logic, the satisfiability modulo theories (SMT) problem is a decision problem for logical formulas with respect to combinations of background theories expressed in classical first order logic with equality. Formally speaking, an SMT instance is a formula in first order logic, where some function and predicate symbols have additional interpretations, and SMT is the problem of determining whether such a formula is satisfiable.

This article shows how we can use an SMT solver in developing a key generator. We need to find valid keys while also satisfying certain constraints. We will use the Z3 SMT Solver, as it is quite easy to use and also has a nice python API to code against.

Welcome to another of my tutorials. Today we will be working on KeyLilBro1 a VB6 keygenme. No P-Code this time so we are going to have to do a little more thinking.

14. #### MD5 Keygenning

Hello everyone. Long time I didn't write any tutorials. Thats because lot of things. Anyway here I am with my new MD5 related tutorial. It's focused on MD5 (and modifyed) encryption scheme. As always I'll try to explain everything so at the end of this tutorial you will be MD5 cracker.

With this tutorial comes one keygenme which I made for you so we can practice on it. I also added some sources for masm32 to help us hash MD5. Its good to know that "MD5" stands to "Message Digest 5".

18. #### Reversing Zuma555 CrackMe #3

Decided to get back into reversing after a very long hiatus, in which now I must revise my skills to get back in top form. Figured this was also a good time to write a tutorial in cryptographic keygenning for beginners. This tutorial assumes you have some basic reversing knowledge, as well as familiarity with unpacking basic packers with the ESP trick.

21. #### Solving the 1999 DAMN Official Contest

Hello and welcome to another Office Jesus tutorial paper. Today, we are going back in time to 1999 for a blast from the past. In the year 1999, tHE EGOiSTE! (tE!) developed and released an official "Joining Contest" in the form of a crackme/keygenme for the group DAMN. The group itself was fairly popular with notable members, including Ivanopulo. While the group died many years ago, their legacy lives on. In our case, we are going to solve one of the group's admittedly easier public challenges. Although this challenge is now 15 years old, there is still much that young reversers can learn from it. For this challenge, we will be unpacking, serial fishing, patching, and keygenning. So, get your OllyDBG ready, and let's begin!
