Useful tools for CTF

I've selected useful and must-have tools for CTF games and computer security competitions. Most of this tools are often indispensable during the games (especially task-based/jeopardy CTF games).
I've combined tools by categories just like in CTF games: Reverse, Steganography, Networking, Forensics, Cryptography, Scripting.
Most of tools are cross-platform, but some of them are only for Windows or Linux.
Here the light and dark editions of cheat sheets/posters with tools:
Утилиты, программы и тулзы для CTF игр

  1. Hope you don't mind me copying and pasting this on my site also. Really good useful tools that you provided.
