Image Encryption

A fun attempt at applying Vigenere Cipher to images

Note: The project was made and tested only on JDK8. It might or might not work on other versions. You can downoad JDK8 from here

Usage

Download the JAR file from releases section.

Just like Vigenere Cipher it uses a main data and key. The only difference is tha both data and key should be images. The dimensions don't need to be same the program will adjust the dimensions of the key_image by itself.

The syntax to use the program is

java -jar image-encryption.jar /path/to/main_image.jpg /path/to/key_image.jpg -O /path/to/outputImage.jpg

Example:

java -jar image-encryption.jar ~/Pictures/taj_mahal.jpg ~/Pictures/joker.jpg -O ~/Pictures/generated_image.png

Showcase

Encrypted image of samples/taj_mahal.jpg by using samples/eiffel_tower.jpg as a key Notice how the program matches the dimensions of key image to that of main image

Encrypted image of samples/hagia_sophia.jpg using samples/nasir_al_mulk.jpg as key.

Encrypted image of samples/taj_mahal.jpg using samples/hagia_sophia.jpg as key
