Steganography is the art of hiding a secret message within a normal message. This is used to transfer some secret message to another person; with this technique, no one else in between will know the secret message you wanted to convey.

This art of hiding secret messages has been used for years in real-life communications. Since the evolution of digital communication, it has also been used in digital conversations.

This software can hide your secret message behind the image file, wav file, mp3 file and many other file format will support in future soon if you will contribute it will be good to me thanks

Stego is an open-source and free steganography tool that lets you hide your secret message in an image or audio file. You will not notice any change in the image or audio file. However, your secret file will be inside the original image or audio file.

This is command-line tool. Therefore, you need to learn the commands to use the tool. Commands will be used to embed files in the image or audio file. In addition, to extract your file from the image or audio file, you need to use another command.

Stego is written in python3 so you need python3 to use it

First clone the repo and follow the given step

git clone https://github.com/W1LDN16H7/StegoCracker.git 

Change the dir to Stego

cd Stego

Run setup.py with python3 to install all the dependencies

python3 setup.py install 

Or you can install manually

python3 -m pip install -r requirements.txt 

After all that done run install.sh file in your terminal

chmod  x install.sh && ./install.sh 

Now it's all done

You can check it by running from anywhere in the terminal

stego -h 

Congratulation you have installed the stego

• Convert mp3 to wav

If you want to hide a secret message in a audio file, but it's a mp3 file, than you should use a stego -c feature to convert it into a wav file

let's see

stego -c -f s.mp3 -out 26.wav 

A new file named 26.wav will generate, and you can go further

• Encoding Message in wav file

For hiding the message or data in wav file you need to run the command like this

stego -f 23.wav -out 24.wav -m "hello this is stego" -e 

as you can see it's done.Now we will try to decode the message.

• Decoding Message from an audio file

For decoding the data you need to have a wav file and turn the stego's decode mode on.

stego  -d -f 24.wav

Wow we get the same message

As we saw we encoded tha data in audio files now we will use stego to encode the data in images

As we know the stego only support png,jpeg format till now but in future I will extend the support to some other file format. But if you can do this it will be amazing to everyone please contribute if you're interested in it,extend the features.

• Encode message in image file

stego - i c.png -o out.png -e -m "Hello this is stego blah blah" 

• Decoding data from the image files

For decoding use it like this..

stego -d  -r out.png
