Use the Web Crypto API to generate hashes
With the new crypto APIs supported in the browsers, you no longer need an external library to generate the hash of a value.
The function that does that is the crypto.subtle.digest(algo, buffer). It returns a Promise with the result as an ArrayBuffer. And since it also expects a Buffer, you'll need some conversions to provide a hex string.
To calculate the SHA-1 hash of a string, use:
// encode as UTF-8
const msgBuffer = new TextEncoder('utf-8').encode(message);
// hash the message
const hashBuffer = await crypto.subtle.digest("sha-1", msgBuffer);
// convert ArrayBuffer to Array
const hashArray = Array.from(new Uint8Array(hashBuffer));
// convert bytes to hex string
const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
return hashHex;
The supported algorithms are SHA-1, SHA-256, SHA-384, and SHA-512.
Just keep in mind that it is an asynchronous function, so either you'll need to handle Promises directly, or use async/await.
