Convert MD5 string to base64 in javascript

As we've seen in earlier posts, you can create an MD5 hash of a string and generate a hash in string type.

This implementation is for Node.js and server-side frameworks like Expressjs. In case you are looking for a JavaScript on the frontend (Javascript, React.js, Vue.js etc.,), implementation using CryptoJS module for JavaScript.

In the code below, we are going to create an MD5 hash using the default crypto module and then we use Buffer.from() method to create a buffer from the hash string and then encode the string in base-64.

import { createHash } from "crypto";
const yourString = "password";
const hash = createHash("md5").update(yourString).digest("hex");
const b = Buffer.from(hash).toString("base64");
console.log(b);

The output of the above code will be a base64 string-

I'm glad that you found this article to create a base64 string out of md5 hash useful. Happy Coding.
