Software cracking has a long history, inseparably linked to the development of the first commercial applications for platforms such as the Apple II, Atari 800 and Commodore 64, where software developers, mainly gamers, struggled with the illegal use of their products, creating ever better security systems. Parasoft C++ Test was used for code quality analysis. In developing of the application Microsoft Visual Studio 2003 version was used. The final goal of the work is to create a sample security software, using the described methods to protect applications from being broken. The aim of this work is to present various methods of cracking software, using all available techniques and modern tools, such as debuggers, disassemblers and decompilers, etc. Software is a valuable asset, the result of hundreds of hours of design, programming and testing, which is why protecting software against cracking and, consequently, against illegal use is so important nowadays. I haven't picked up my master's diploma until today. Defended at grade A, making me a master's degree in banking LOL. The following article is my thesis from 2009, while I had to save myself from forced recruitment to the army. Handling of the executable file structure

Graphical interface of the protection application Working principle of the software protection system Detection of tools to assist in cracking applications Protection against modification of files and memory

Anti executable serial
