% program for RSA

clc;clear all;close all;

disp('RSA algorithm');

%=============================================================

% Secret data:

inImg=imread('G:\Data_Security\Code\FINAL_CODE\Graduation_project\baby_img\2.jpg');

% inImg = imread('lena.jpg');

s = size(inImg);

% Encryption:

enImg = ones(s);

n=7;e=33;

for i = 1:s

for u=1:s(1) % iterate over each row

for v=1:s(2) % iterate over each column

enImg(u,v) = i_encrypt(inImg(u,v),n,e);

end

end

end

% show

imshow(enImg)

Please do not follow up with the code to i_encrypt() because discussing encryption techniques is not allowed here.
