steganoCracker

open source steganography tool to hide information inside pictures

steganoCracker is a cross-platform steganography tool written in Python, with its GUI designed in PyQt6.
It's main purpose is to hide and reveal text in image files.
I created this application for my own use, as it is very useful in many of CTF competitions that I participate in.

Features

• Two modes - writing and reading to/from image files
• Supports all six possible subpixel layouts (RGB, RBG, GRB, GBR, BRG, BGR)
• Works in three different patterns (horizontal, vertical, diagonal)
• You select pixels order, from lowest to highest or the other way around

Screenshots

Down below you can see, that my application successfully recovered flags from both BCACTF-4.0 and MSHP 2023 CTF image files:
