Stego is a very straightforward implementation of lsb image steganography. It encodes and decodes data into an image. The data or message is hidden in the LSBs of the Red, Green and Blue image components. The package provides both, encoder and decoder, as well as an additional command line tool to easily hide data within and extract hidden data from image files.
