i have developed for gray scale image i dont know to change it to colour.As per the algorithm each color has to encrpted individually .Can u help??

i have done the encryption for black and white images but the processing time is high as the size increases.i want a help to lower the process time. i like to know how to modify for color images.i have done the encryption using the base paper"A hash based image encryption algorithm" from a journal published by Elsevier
