REVERSING: Study and programming of a KEYGEN.
1. Introduction and Objectives In this article, we are going to superficially explain how certain software licenses are generated. To do this, we will study a particular code, with the aim of subsequently programming a key generator that can generate a correct key from any text string. For this, we will need to have at least basic knowledge in assembler programming (ASM), and in reverse engineering. As tools, we will use the OllyDbg debugger and the DevCpp compiler to program the key generator (Keygen) in C/C++. If you are interested in conducting a cybersecurity audit of your applications, you can …
