7. #### 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.

8. #### Keygenning VB6 Key4lilbro1

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.

10. #### 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".

12. #### 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.

14. #### 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!

16. #### Keygenning 8y4hmy3 KeygenMe #12

I made a video presenting an interesting keygenme. In this video you can see what is done and how is done to reverse a keygenme. If is too fast please press pause.

Steps:

1. Running for the first time the keygenme
2. Detecting protection
3. Unprotecting
4. Analyse of the algo
5. Creating the keygen in VB. NET Express 2010
6. Bug testing
7. Finalising keygen
8. Testing keygen

Hope someone will find this useful.

This KeygenMe is coded in Microsoft VC++ 6.0 (you can check with PeiD ) and not use of Hash Crypto's (you can check via KANAL Plugin in PeiD). In this KeygenMe we need to solve 2 algorithms so I have decided to explain all the steps to you.

24. #### Keygenning Encrypto KeygenMe #5

A tutorial on how to reverse a challenge from an old pal Encrypto that I have found lately and I have never reversed until now. The ultimate goal of the challenge is to code a standalone keygen and this is what I have done. The tutorial is a little bit long since it is provided with details so anyone can watch and give it a try.

If you get any kind of problems will be happy to help!
