I had made a project on image steganography using django and react. The backend was done using opencv for python. And frontend was done using react js. Basically it was web application in which we were supposed to give input of 2 images and using concept of steganography the program will hide image 1 in image 2. And then there was decryption tab which will decrypt the image which was encrypted. Also we had implemented login logout features. It was fun and me and my team got a lot to learn about web development from that project.
