In v2.0, I have fixed a major bug with algorithm. Initially, it encoded from the top of the image to the bottom of the image instead of left to right because I switched the "row" and "col" variables. That's fixed now.
Other minor changes include added documentation in terms of contributing, licensing. and a code of conduct. I have also added some disclaimer text to the program like "for educational use only" etc.
About BPStegano
BPStegano uses AES-128 encryption to encrypt any type of data you select for hiding inside an image. It uses a custom hiding algorithm with LSB encoding to distribute the data throughout the image. BPStegano supports the hiding of plaintext strings and any type of file (multiple files are supported - limited only by the size of the image).
