🔐 Asymmetric Encryption 🔑
Generate Public-Private keypair on your server for asymmetric encryption and decryption
- Generate public key and private key in the server.
- Forward the public key to your apps (website or app)
- Have your app generate a random key for encryption.
- Encrypt the message using the random key generated by your app.
- Encrypt the random key using the public key supplied by the server.
- Send to the server both the encrypted message and the encrypted random string.
- On the server end decrypt the encrypted string sent by the client using private key.
- 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
-----BEGIN PUBLIC KEY-----
