Curs Javascript


jsSHA este o implementare JavaScript a intregii familii de hash-uri SHA dupa cum sunt definite in FIPS PUB 180-4 si FIPS PUB 202 (SHA-1, SHA-224, SHA3-224, SHA-256, SHA3-256, SHA-384, SHA3-384, SHA-512, SHA3-512, SHAKE128, si SHAKE256), precum si HMAC, definit in FIPS PUB 198-1.
jsSHA e compatibil cu toate navigatoarele web care suporta JavaScript; functioneaza si cu Node.js.

Utilizare

Includeti fisierul JavaScript sha.js in header-ul paginii:
<script src='/path/to/sha.js'></script>

- Folositi urmatoarea sintaxa sa obtineti tipul de hash dorit: 
// SHA-Type: SHA-1, SHA-224, SHA3-224, SHA-256, SHA3-256, SHA-384, SHA3-384, SHA-512, SHA3-512, SHAKE128, SHAKE256
// Input_Type: HEX, TEXT, BYTES, ARRAYBUFFER, B64 (Base-64)

var sha_ob = new jsSHA('SHA-Type', 'Input_Type');
sha_ob.update('Add your text');
var hash = sha_ob.getHash('HEX');
1. Creati o instanta de obiect jsSHA (aici sha_ob), cu new jsSHA() cu tipul de hash dorit ('SHA-Type'), si tipul de sir adaugat ('Input_Type').
- Tipul de hash ('SHA-Type') poate fi unul dintre urmatoarele: SHA-1, SHA-224, SHA3-224, SHA-256, SHA3-256, SHA-384, SHA3-384, SHA-512, SHA3-512, SHAKE128, SHAKE256.
- Pentru tipul de sir puteti adauga unul din urmatoarele': HEX, TEXT, BYTES, ARRAYBUFFER, B64 (B64 e pentru Base-64).
2. Apoi apelati metoda update, sha_ob.update() cu textul dorit.
3. La urma apelati sha_ob.getHash() cu tipul de rezultat dorit (B64, HEX, BYTES, ARRAYBUFFER).

HMAC

var sha_ob = new jsSHA('SHA-Type', 'Input_Type');
sha_ob.setHMACKey('my_key', 'TEXT');
sha_ob.update('Add your text');
var hmac = sha_ob.getHMAC('HEX');
1. Creati o instanta de obiect new jsSHA() la fel ca pentru Hash.
2. Apoi setati cheia HMAC cu metoda sha_ob.setHMACKey(), adaugand cheia dorita (aici 'my_key'), si tipul de text care va fi adaugat (aici TEXT). Aceasta se defineste inainte de sha_ob.update().
3. Apoi adaugati textul dorit cu update, la fel ca la hash, sha_ob.update('Text..').
4. La urma obtineti sirul HMAC apeland metoda sha_ob.getHMAC() cu tipul de rezultat dorit (B64, HEX, BYTES, ARRAYBUFFER).

La setHMACKey() se adauga acelasi tip de sir ca si la constructor (jsSHA() ).
Metoda getHMAC() poate sa preia aceleasi tiupuri de sir ca si getHash().

- Nu se poate calcula hash-ul si HMAC cu aceeasi instanta de obiect.

Exemplu care sa calculeze HMAC-ul SHA-512 a sirului "Peace is Good" cu cheia "ab3": 
var sha_ob = new jsSHA('SHA-512', 'TEXT');
sha_ob.setHMACKey('ab3', 'TEXT');
sha_ob.update('Peace is Good');
var hmac = sha_ob.getHMAC('HEX');

alert(hmac)

Node.js

jsSHA e disponibil prin NPM si poate fi instalat cu:
npm install jssha

Ca sa folositi acet modul, intai adaugati-l in script cu require():
jsSHA = require('jssha';);

Calculeaza online Hash-uri SHA si HMAC
