A program for encoding information in image and audio files through steganography. Any type of data can be encoded, from raw strings to files, as shown below:

<p align="middle"> <img src="https://github.com/kamihfkjkf/stegpy/blob/master/images/house.png?raw=true"/> <img src="https://github.com/kamihfkjkf/stegpy/blob/master/images/_cat.jpeg?raw=true"/> </p>

On the left, a house with a steganographically hidden image. On the right, the extracted hidden image of a cat. It is revealed by removing all but the least significant bit of each color component in the host image.

Supported host formats

Images in a different format are automatically converted to PNG. Different audio formats are not supported at all.
