const crypto = require('crypto');

  const key = Buffer.from(crypto.randomBytes(32), 'binary');
  const iv = crypto.randomBytes(16);
  const cipher = crypto.createCipheriv('aes256', key, iv);

  let data = cipher.update(message, 'utf8', 'base64');
  data += cipher.final('base64');

  const encryptedKey = crypto.publicEncrypt({
    key: publicKey,
    padding: crypto.constants.RSA_PKCS1_PADDING
