stegano 0.4.5

A Python Steganography module.

Stéganô

A Python Steganography module.

Installation

$ sudo pip install Stegano

Use Stéganô as a library in your Python program

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

>>> from stegano import slsb
>>> secret = slsb.hide("./pictures/Lenna.png", "Hello Workd")
>>> secret.save("./Lenna-secret.png")

Use Stéganô as a program

In addition you can use Stéganô as a program.

Example:

$ slsb --hide -i ../examples/pictures/Lenna.png -o Lena1.png -m "Secret Message"

Another example (hide the message with Sieve of Eratosthenes):

$ slsb-set --hide -i ../examples/pictures/Lenna.png -o Lena2.png --generator eratosthenes -m 'Secret Message'

Examples

There are some examples in the folder examples.

This release introduces a more advanced LSB (Least Significant Bit) method based on integers sets. The sets generated with Python generators (Sieve of Eratosthenes, Fermat, Carmichael numbers, etc.) are used to select the pixels used to hide the information. You can use these new methods in your Python codes as a Python module or as a program in your scripts.

0.3 (2011-04-15)

• you can now use Stéganô as a library in your Python program; (python setup.py install) or as a ‘program’ thanks to the scripts provided in the bin directory;

• new documentation (reStructuredText) comes with Stéganô.

0.2 (2011-03-24)

• this release introduces some bugfixes and a major speed improvement of the reveal function for the LSB method. Moreover it is now possible to hide a binary file (ogg, executable, etc.);

• a new technique for hiding/revealing a message in a JPEG picture by using the description field of the image is provided.
