Professional software analysis solutions enable developers to gain a deeper understanding of how software works, so as to identify the defects, compliance, security, interoperability, and performance issues in the software development process. This same applies to software developers, software debuggers, and reverse engineers.

With the continuous development of processor technology, the 64-bit operating system came out. Later on, the 64-bit applications began to spread widely too. In the field of reverse engineering (i.e.: software cracking), the classic and traditional OllyDbg can only perform reverse analysis on 32-bit applications. At this time, you need to know there is another debugging software that specially designed for analyzing both 32-bit and 64-bit programs - x64dbg.

Restorator (AKA: Restorator 2007) is a professional and easy-to-use executable file resource editing and software localization tool from Germany, comes with intuitive user interface, as well as complete tutorials, examples and prompts. Its working principle is similar to eXeScope, Resource Hacker or XN Resource Editor, but it's far more better then all of them in terms of convenience and functionality.

Whether you wish to be a hacker who is interested in hacking wireless network, web app, database; cracking password, software....; or want to engage in cyber security related works in the future, Offensive Security's Kali Linux (a penetration testing OS) should be always your main "battlefield" and "experimental field".

PEiD (short for PE iDentifier) is a well-known professional packer/cryptor/compiler detecting tool. It's so powerful that it can detect the types/signatures of almost any PE file packing tools (at present, the number has been more than 600 kinds). In addition to the official version, AppNee also provides you its full-plugin version, which can be treated as the most perfect one version (contains 60+ plugins and necessary runtime library files: mfc70.dll, msvcr70.dll, rtl70.bpl, vcl70.bpl) on the Internet at present. I do believe reverse engineers or software cracking/unpacking enthusiasts must like it very much.
