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?

To generate an SSH private/public key pair for your use, you can use the ssh-keygen command-line utility. You can run the ssh-keygen command from the command line to generate an SSH private/public key pair. If you are using Windows, by default you may not have access to the ssh-keygen command.
The public key is used to encrypt messages and the private key is used to decrypt messages. The reverse is done to create a digital signature. Only the owner of the key pair knows the private key, but everyone can know the public key.
The public key is used to send cryptocurrency into a wallet. The private key is used to verify transactions and prove ownership of a blockchain address. If someone sends you, say one bitcoin (BTC), a private key will be required to “unlock” that transaction and prove that you are now the owner of that bitcoin.
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. }); If you love us?
