What is jssha?

jsSHA is a JavaScript library that provides various cryptographic hash functions and HMAC (Hash-based Message Authentication Code) functionalities. It supports a wide range of hash algorithms including SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3-224, SHA3-256, SHA3-384, SHA3-512, and SHAKE128/256.

What are jssha's main functionalities?

Hashing

This feature allows you to create a hash of a given input text using various algorithms. In this example, SHA-256 is used to hash the input text 'This is my input text' and the result is output in hexadecimal format.

const jsSHA = require('jssha');
const shaObj = new jsSHA('SHA-256', 'TEXT');
shaObj.update('This is my input text');
const hash = shaObj.getHash('HEX');
console.log(hash);

HMAC

This feature allows you to create an HMAC using a specified key and input text. In this example, SHA-256 is used to create an HMAC for the input text 'This is my input text' with the key 'my-secret-key', and the result is output in hexadecimal format.

const jsSHA = require('jssha');
const shaObj = new jsSHA('SHA-256', 'TEXT');
shaObj.setHMACKey('my-secret-key', 'TEXT');
shaObj.update('This is my input text');
const hmac = shaObj.getHMAC('HEX');
console.log(hmac);

SHAKE

This feature allows you to use the SHAKE (Secure Hash Algorithm Keccak) function, which is a variable-length hash function. In this example, SHAKE128 is used with an output length of 256 bits to hash the input text 'This is my input text', and the result is output in hexadecimal format.

const jsSHA = require('jssha');
const shaObj = new jsSHA('SHAKE128', 'TEXT', {shakeLen: 256});
shaObj.update('This is my input text');
const shake = shaObj.getHash('HEX');
console.log(shake);
