This is a small program implementing one of the most basic steganography techniques for storing information in bmp images. It hides the text by replacing the last bit of each byte of the original image. Hence, if we have a 1920x1080 24-bit bmp image, it will contain 2 073 600 pixels = 6 220 800 bytes, which means we can hide 759 kB of information. The program works both from the command line and interactively. The source code can be found here.
