Encryption in nodejs

Question

I\'m trying to port the following php code to javascript on node.js:

$mac = hash_hmac(\'SHA256\', \'string\', \'secret\', true);
$coded = base64_encode($mac);

Answer 1

The method is called createHmac

> Crypto = require('crypto');
{ Credentials: [Function: Credentials],
  createCredentials: [Function],
  Hash: [Function],
  createHash: [Function],
  Hmac: [Function],
  createHmac: [Function],
  Cipher: [Function],
  createCipher: [Function],
  createCipheriv: [Function],
  Decipher: [Function],
  createDecipher: [Function],
  createDecipheriv: [Function],
  Sign: [Function],
  createSign: [Function],
  Verify: [Function],
  createVerify: [Function],
  DiffieHellman: [Function],
  createDiffieHellman: [Function],
  pbkdf2: [Function],
  randomBytes: [Function],
  pseudoRandomBytes: [Function],
  rng: [Function],
  prng: [Function] }

Answer 2

You want to use the createHmac function instead.

Crypto.createHmac("SHA256", 'secret').update('string').digest('base64')
