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

Question

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?

Answer 1

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. });
