Steganography

Python program based on steganographical methods to hide files in images.

Information

• encode_image(msg, img_loc, out_loc) takes message(msg) and hides it in image(img_loc) and saves in out_loc. default ouput file is "encoded_image.png". msg can be either file or string.
• decode_image(img_loc) takes image and finds hidden message. If output file isn't specified(see usage) hidden message will be displayed on terminal.

Note that, program only supports RGB images and output image has to have .png extension.
