Installation

One Line Setup

Use the following command for faster setup:

Command For Ubuntu Based Distros

sudo apt install python3-pip && sudo apt install git && git clone --depth=1 https://github.com/xerohackcom/Chaya.git && cd Chaya && pip3 install -r requirements.txt && sudo apt update && sudo apt-add-repository ppa:linuxuprising/libpng12 && sudo apt update && sudo apt install -y libpng12-0

Command For Debian Based Distros

sudo apt install python3-pip && sudo apt install git && git clone --depth=1 https://github.com/xerohackcom/Chaya.git && cd Chaya && pip3 install -r requirements.txt && sudo apt update && sudo apt install build-essential devscripts && cd ~/ && sudo touch /etc/apt/sources.list.d/libpng12.list && echo "deb https://ppa.launchpadcontent.net/linuxuprising/libpng12/ubuntu hirsute main" | sudo tee -a /etc/apt/sources.list.d/libpng12.list && echo "deb-src https://ppa.launchpadcontent.net/linuxuprising/libpng12/ubuntu hirsute main" | sudo tee -a /etc/apt/sources.list.d/libpng12.list && sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 1CC3D16E460A94EE17FE581CEA8CACC073C3DB2A && sudo apt update && sudo apt install -y libpng12-0

Using Installer.py

You can install the dependencies using installer.py script. Run the following commands in terminal:

sudo apt install python3-pip && sudo apt install git && git clone --depth=1 https://github.com/xerohackcom/Chaya.git && cd Chaya

Ubuntu Based Distros

python3 installer.py --ubuntu

Debian Based Distros

python3 installer.py --debian

Usage

Help Menu

python3 chaya.py --help

Automatic Operations

• First add few images (png format) to /autoexp/image_raw/
• Remove the txt file from all autoexp sub-folders to avoid errors!
• Run the following command

python3 chaya.py -enc

Output Data

• Enc + Steg images -> /autoexp/image_steg/
• Enc + Steg + Comp images -> /autoexp/image_steg_comp/
• Cipher data -> /appdata/cipher_data.json
• Analysis data -> /appdata/analysis_results_enc.json

Issues – v1.2.3

• Issue with numpy import (solution under issues)
• Known bug with image-quality library (not fixed)

Future Plan

The plan is to build this into a modular framework where users can also add their custom scripts for encryption and steganography part. Support for multiple compression algorithms is being added. During the experiments, FLIF was supported, but now JpegXL (JXL) is the new best lossless raster based compression. Support for payload execution and other interesting stuff underway. Can be done combining commands, but not inbuilt. Video steganography using ffmpeg is being tested.
