A simple SHA-3 / Keccak / Shake hash function for JavaScript supports UTF-8 encoding.
The js-sha3 npm package is a JavaScript implementation of the SHA3 (Secure Hash Algorithm 3) cryptographic hash function. It provides a simple interface to compute hashes using the SHA3 family of hash functions, including SHA3-224, SHA3-256, SHA3-384, and SHA3-512, as well as the SHAKE128 and SHAKE256 extendable-output functions.
SHA3-256 Hash
This feature allows you to compute a SHA3-256 hash of a given input string. The code sample demonstrates how to import the sha3_256 function from the js-sha3 package and use it to hash the string 'message'.
"use strict"; const { sha3_256 } = require('js-sha3'); const hash = sha3_256('message'); console.log(hash);SHA3-512 Hash
This feature allows you to compute a SHA3-512 hash of a given input string. The code sample demonstrates how to import the sha3_512 function from the js-sha3 package and use it to hash the string 'message'.
"use strict"; const { sha3_512 } = require('js-sha3'); const hash = sha3_512('message'); console.log(hash);SHAKE128 Hash
This feature allows you to compute a SHAKE128 hash of a given input string with a specified output length. The code sample demonstrates how to import the shake128 function from the js-sha3 package and use it to hash the string 'message' with an output length of 256 bits.
"use strict"; const { shake128 } = require('js-sha3'); const hash = shake128('message', 256); console.log(hash);SHAKE256 Hash
This feature allows you to compute a SHAKE256 hash of a given input string with a specified output length. The code sample demonstrates how to import the shake256 function from the js-sha3 package and use it to hash the string 'message' with an output length of 512 bits.
"use strict"; const { shake256 } = require('js-sha3'); const hash = shake256('message', 512); console.log(hash);The 'sha3' package is another implementation of the SHA3 hash function in JavaScript. It provides similar functionality to js-sha3 but may have different API interfaces and performance characteristics.
Crypto-js is a collection of cryptography algorithms implemented in JavaScript. It includes SHA3 among many other cryptographic functions. It is more comprehensive than js-sha3 but might be larger in size and potentially slower due to its broader scope.
The 'keccak' package is a JavaScript implementation of the Keccak hash functions, which are the basis for the SHA3 standard. It offers similar hashing capabilities and is focused specifically on the Keccak family of hashes.

You can also install js-sha3 by using Bower.
bower install js-sha3
For node.js, you can use this command to install:
npm install js-sha3
You could use like this:
sha3_512('Message to hash');
sha3_384('Message to hash');
sha3_256('Message to hash');
sha3_224('Message to hash');
keccak512('Message to hash');
keccak384('Message to hash');
keccak256('Message to hash');
keccak224('Message to hash');
shake128('Message to hash', 256);
shake256('Message to hash', 512);
cshake128('Message to hash', 256, 'function name', 'customization');
cshake256('Message to hash', 512, 'function name', 'customization');
kmac128('key', 'Message to hash', 256, 'customization');
kmac256('key', 'Message to hash', 512, 'customization');
// Support ArrayBuffer output
var arrayBuffer = keccak224.arrayBuffer('Message to hash');
// Support Array output
var bytes = keccak224.digest('Message to hash');
var bytes = keccak224.array('Message to hash');
// update hash
sha3_512.update('Message ').update('to ').update('hash').hex();
// specify shake output bits at first update
shake128.update('Message ', 256).update('to ').update('hash').hex();
// or to use create
var hash = sha3_512.create();
hash.update('...');
hash.update('...');
hash.hex();
// specify shake output bits when creating
var hash = shake128.create(256);
hash.update('...');
hash.update('...');
hash.hex();
// specify cshake output bits, function name and customization when creating
var hash = cshake128.create(256, 'function name', 'customization');
// specify kmac key, output bits and customization when creating
var hash = kmac128.create('key', 256, 'customization');
If you use node.js, you should require the module first:
const {
sha3_512,
sha3_384,
sha3_256,
sha3_224,
keccak512,
keccak384,
keccak256,
keccak224,
shake128,
shake256,
cshake128,
cshake256,
kmac128,
kmac25
} = require('js-sha3');
If you use TypeScript, you can import like this:
import {
sha3_512,
sha3_384,
sha3_256,
sha3_224,
keccak512,
keccak384,
keccak256,
keccak224,
shake128,
shake256,
cshake128,
cshake256,
kmac128,
kmac256
} from 'js-sha3';
