🔐 Asymmetric Encryption 🔑

Generate Public-Private keypair on your server for asymmetric encryption and decryption

build passing MIT


  1. Generate public key and private key in the server.
  2. Forward the public key to your apps (website or app)
  3. Have your app generate a random key for encryption.
  4. Encrypt the message using the random key generated by your app.
  5. Encrypt the random key using the public key supplied by the server.
  6. Send to the server both the encrypted message and the encrypted random string.
  7. On the server end decrypt the encrypted string sent by the client using private key.
  8. Using the decrypted key decrypt the message.

This module aims at solving the public key, private key and passphase part of the process.

Installation

npm i --save asymmetric-encryption

or

yarn add asymmetric-encryption

Usage

const encrypt = require("asymmetric-encryption")

const { publicKey, privateKey, passphrase } = encrypt.generateKeyPairSync();
const message = "message";

const enc = encrypt.encrypt(publicKey, message);
const dec = encrypt.decrypt(privateKey, enc);

console.log(publicKey)
console.log(privateKey)
console.log(passphrase)
console.log(dec)

Output should be
