What is sha3?

The sha3 npm package provides implementations of the SHA-3 (Secure Hash Algorithm 3) cryptographic hash functions. It allows you to generate hash digests for data, which can be used for data integrity checks, digital signatures, and other cryptographic applications.

What are sha3's main functionalities?

Generate SHA-3 Hash

This feature allows you to generate a SHA-3 hash for a given input string. In this example, a SHA-3 hash with a 256-bit output is generated for the string 'hello world'.

const { SHA3 } = require('sha3');
const hash = new SHA3(256);
hash.update('hello world');
console.log(hash.digest('hex'));

Generate SHAKE128 Hash

This feature allows you to generate a SHAKE128 hash, which is an extendable-output function (XOF) variant of SHA-3. In this example, a SHAKE128 hash is generated for the string 'hello world' with a 128-bit output.

const { SHAKE } = require('sha3');
const hash = new SHAKE(128);
hash.update('hello world');
console.log(hash.digest({ buffer: Buffer.alloc(16) }).toString('hex'));

Generate SHAKE256 Hash

This feature allows you to generate a SHAKE256 hash, another XOF variant of SHA-3. In this example, a SHAKE256 hash is generated for the string 'hello world' with a 256-bit output.

const { SHAKE } = require('sha3');
const hash = new SHAKE(256);
hash.update('hello world');
console.log(hash.digest({ buffer: Buffer.alloc(32) }).toString('hex'));
