msteg 💾 🔍

A mini steganography program for hiding data in files (Currently only BMP files).

Installing

Use make to compile from source.

git clone https://github.com/buzzqrd/msteg
cd msteg/
make

After making, install msteg with

sudo make install

Usage

To list that stats of a file, run the following command:

msteg --stat [file]

Write a string into a file:

msteg -w [file] "string"

Read string out of file:

msteg -r [file]

Writing a file into the media

To embed the file:

msteg -w -i [input-file] [media]

To extract the file:

msteg -r -o [output] [media]

Updates

msteg is an ongoing, longterm project. In time, this project aims to support all forms of media that can encapsulate data. In the future, this project should be updated to include a better and wider range of steganographic methods. The current supported media types are:

  • BMP (Bitmap Images)

Upcoming updates will soon include a man page and help page, as well as better support for stdin and stdout.

Future Plans

  • PNG support
  • Variation in bit usage (not just the lowest order bit)
  • Passcodes to change the encoding pattern

Contributing

Contributions are welcome to this repository. The main goal of this project is to make a simple, lightweight, portable C implementation of a steganographic tool. Any contributions that help to fulfill this goal are greatly appreciated.
