Rebane's CTF tools

This is a set of tools I've written to aid in my tasks, mainly in CTFs
Feel free to use this stuff, but keep in mind it's very much work in progress and if something doesn't work that's normal
If you wish to, submit issues and pull reqs

Tool Overview

Decode

decoder.py

A decoding tool, broken atm

missingno.py

A decoding tool, that automatically detects the encoding of a string and decodes it
It can also work recursively for those CTF challs where some jerk did 42 layers of base64
Supported encodings: binary, hex, base64, urlsafeb64, brainfuck, urls with rot

Generic

searchflags.sh

Looks for a CTF flag recursively through all files and their strings
Looks for plaintext and hex, b64 planned
Only works on Linux or WSL

Stego

pixelprocess_img.py

Processes every pixel of an image
Useful for writing your own image manipulation/stego tools/scripts

pixelprocess_new.py

Like pixelprocess_img, but it will generate and save a new image instead of going through an existing one

fixqrcode.py

Attempts to fix a broken QR code to make it readable again
Supports fixing: position, alignment and timing patterns, version and format information

bruteqrcode.py

Bruteforces fixing a QR code by using fixqrcode.py
