Steganography library written in python
You can use Stany to encode any text message or binary file inside an arbitrary RGB/RGBA image. The payload will be encrypted with AES and embedded inside the pixels' least significant bits.
A Streamlit app is also provided to facilitate the use of Stany.
A possible use is to encode a book you just wrote or confidential documents inside any image. This way your documents will always stay with you and go unnoticed by everyone.
- Encode plain texts messages
- Encode compressed files
- Encrypt messages with AES
- Use dynamic number of least significant bits
Creave virtual env with 3.7 >= python <= 3.9 (untested for other versions), then run:
pip install -r requirements.txt
from PIL import Image
from stany import encode, decode
img = Image.open("path-to-my-img.png")
message = "Hello world"
encoded_img, secret_key = encode(img, message)
decoded_message = decode(encoded_img, secret_key)streamlit run app/main.py- Add tests
- Hide message inside high entropy locations
