Get Supported Hash Algorithms in Node.js

Retrieve the list of supported hash algorithms in your Node.js version using the crypto.getHashes() method. This method returns a list of strings identifying the individual algorithms, like md5, sha256, sha3-256, and so on:

import crypto from 'node:crypto'

const supportedHashAlgorithms = crypto.getHashes()

// ['RSA-MD5', 'RSA-SHA256', 'sha1', 'sha256', 'sha3-256', … <many more>]

Please notice that we shortened the sample list of hashing algorithms to more known ones.

We printed the list of hashing algorithms using:

  • Node.js v16.16
  • with OpenSSL 1.1.1.

Enjoy hashing in Node.js!
