My first and one of the simplest ways of steganography.
run "python3 steganography.py Picturename [Data which you would like to hide]" to Hide the data in the picture. E.g:
python3 steganography.py space_wallpaper.jpg This should be the hidden data
run "python3 decrypt_steganography.py Picturename [File to which the data will be saved]" to get the hidden data from the picture. E.g:
python3 decrypt_steganography.py space_wallpaper_steganography.png data.txt
"Max Data Size in Byte" = "Image height" _ "Image width" _ 0.25
