How to create a pair private public keys using Node js crypto

0 votes
I have to generate two keys (private and public) to encrypt a text with the public and let the user with the private key decrypt the text.

Is it possible with the module Crypto?

Hello @kartik,

nodejs v10.12 now supports this natively with crypto.generateKeyPair

const { generateKeyPair } = require('crypto');
generateKeyPair('rsa', {
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret'
  }
}, (err, publicKey, privateKey) => {
  // Handle errors and use the generated key pair.
});

Hope it helps!!
