lsb_steganography

Python program based on least significant bit (LSB) steganography, one of the basic stegonographical methods to hide data inside an image.

Usage

Embed a secret message into a cover image using LSB

Encoding Usage : python lsb_steg.py -e < cover_img > < outfile > < secret_message >

Positional Arguments ->

cover_img       :    path to cover image

outfile         :    path to output file

secret_message  :    Enter your message that needs to be hidden

Make sure to add the extension for the outfile except the jpg(jpeg) format as it is difficult

Extract a secret from a steganographic image using LSB on the red channel

Decoding Usage : python lsb_steg.py -d < steg_img > < outfile >

Positional Arguments ->

steg_img        :    path of the steg image

outfile         :    path to the output file

For help : python lsb_steg.py -h or python lsb_steg.py --help
