CryptoCom

A CLI that helps in encrypting and decrypting an image with the help of a key , so that the user has the control of the images. You have to install the latest version of NODE and Windows 10 or even higher version OS. JPG/JPEG are lossy formats and hence few pixels are changed in the process. PNG format is a non lossy format and hence images are perfect in this process.
