Convert SHA-512 string to base64 in javascript

As we've seen in earlier posts, you can create an SHA-512 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 SHA-512 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("sha512").update(yourString).digest("hex");
const b = Buffer.from(hash).toString("base64");

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 sha512 hash useful. Happy Coding.
