encrypt-image

How to use

Step - 1

Import the library

import { image } from "encrypt-image";

Step - 2

Generate keys using generateKeys() function and it will return public key , private key and symmetric key.

const keys = image.generateKeys();

Step - 3

use encrypt() function and pass the image , public key and symmetric key.

const encryptedImage = image.encrypt(image, keys.publicKey, keys.symmetricKey);

use decrypt function to get the original image , in this function just pass private key (keys.privateKey)

const encryptedData = fs.readFileSync('encrypted.bin');

const decryptedImage = image.decrypt(encryptedData,keys.privateKey);

can store decrypted image file using writeFileSync Function

fs.writeFileSync('decrepted.jpg',decryptedImage);

Example of encryption and decryption of image :

import { image } from "encrypt-image";
import fs from 'fs'

const keys = image.generateKeys();

const img = fs.readFileSync('image.jpg')

const encryptImage = image.encrypt(img, keys.publicKey, keys.symmetricKey);

const decryptedImage = image.decrypt(encryptedData,keys.privateKey);

fs.writeFileSync('dec.jpg',decryptedImage);

Example of encryption and decryption of Text :

import { text } from "encrypt-image";

const Keys = text.generateKeys();
const plaintext = "Hi this Encryption";
const encryptedText = text.encrypt(plaintext, Keys.publicKey);

console.log(encryptedText);

const decryptedText = text.decrypt(encryptedText,Keys.privateKey);

console.log(decryptedText);
