Python stegonography tool with builtin encryption/obfuscation of the data.
This tool works in both Python2 and Python3. The only requirement is the pillow library.
By default, places 6 bits of data into each pixel of a .png-type file. It does this by overwriting the 2 least-significant bits in each band (R,G,B). Only tested with .png files, but will probably work with .bmp files as well.
Features built-in encryption, using Python's random library. This roughly means the data is encrypted using Mersenne twister.
There is no "main", you will need to import the code into your project.
def steg(image, data_file, output_file)
You can call it like:
steg("C:\\my_picture.png", "E:\\some_document.pdf", "C:\\my_picture_stego.png")
desteg() works in a similar fashion:
def desteg(image, savefile)
There are two OPTIONAL arguments at the end of each funtion:
def steg(image, data_file, output_file, BITS_TO_SHIFT=2, BANDS_TO_USE=3)
def desteg(image, savefile, BITS_TO_SHIFT=2, BANDS_TO_USE=3)
These determine how many least-significant bits and how many bands (R,G,B) to write data to.
