Build a Website

Hi, I have a program ready, which reads an image then the data(say length 4byte) that needs to be encrypted within the image, it then encrypts the data then divides the data in 4 parts then , create 4 replicas of the original image and save each part in an image. At time of retrieval follows the process in reverse. Here I can replace my encryption algorithm and use blowfish. so what say, I have 6 years of java development exp and my all previous projects has a rating of 5/5 Looking forward to work with you
