Stéganô, a pure Python Steganography module.

$ sudo pip install Stegano

You will be able to use Stéganô in your Python programs or as a command line tool.

A tutorial is available.

If you want to use Stéganô in your Python program you just have to import the appropriate steganography technique. For example:

>>> from stegano import lsb
>>> secret = lsb.hide("./tests/sample-files/Lenna.png", "Hello World")
>>> secret.save("./Lenna-secret.png")

$ lsb hide -i ./tests/sample-files/Lenna.png -m "Secret Message" -o Lena1.png

$ lsb-set hide -i ./tests/sample-files/Lenna.png -m 'Secret Message' --generator eratosthenes -o Lena2.png

The message will be scattered in the picture, following a set described by the Sieve of Eratosthenes. Other sets are available. You can also use your own generators.

This will make a steganalysis more complicated.

$ python -m unittest discover -v
