Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including md5-hex with all npm packages installed. Try it out:

var md5Hex = require("md5-hex")

md5-hex v3.0.1

Create a MD5 hash with hex encoding

md5-hex Build Status

Create a MD5 hash with hex encoding

Please don't use MD5 hashes for anything sensitive!

Works in the browser too, when used with a bundler like Webpack, Rollup, Browserify.

Checkout hasha if you need something more flexible.


$ npm install md5-hex


const fs = require('fs');
const md5Hex = require('md5-hex');

const buffer = fs.readFileSync('unicorn.png');

//=> '1abcb33beeb811dca15f0ac3e47b88d9'




Type: Buffer | string | Array<Buffer | string>

Prefer buffers as they're faster to hash, but strings can be useful for small things.

Pass an array instead of concatenating strings and/or buffers. The output is the same, but arrays do not incur the overhead of concatenation.


  • crypto-hash - Tiny hashing module that uses the native crypto API in Node.js and the browser
