drbg.js

Deterministic Random Bits Generators

Based on NIST Recommended DRBG from NIST SP800-90A with the following properties:

• <s>CTR DRBG with DF with AES-128, AES-192, AES-256 cores</s> see issue #1
• Hash DRBG with DF with SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 cores
• HMAC DRBG with SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 cores
• <s>with</s> and without prediction resistance

Installation

npm install drbg.js

Usage

var drbgs = require('drbg.js') // import HashDRBG and HmacDRBG
var HashDRBG = drbgs.HashDRBG // or require('drbg.js/hash')
var HmacDRBG = drbgs.HmacDRBG // or require('drbg.js/hmac')

var drbg2 = new HashDRBG('sha256', entropy, nonce, personalization_data)
drbg2.generate(5, additional_data) // <Buffer qq qq qq qq qq>
drbg2.reseed(entropy, personalization_data)
drbg2.generate(5, additional_data) // <Buffer ww ww ww ww ww>

var drbg3 = new HmacDRBG('sha256', entropy, nonce, personalization_data)
drbg3.generate(5, additional_data) // <Buffer ee ee ee ee ee>
drbg3.reseed(entropy, personalization_data)
drbg3.generate(5, additional_data) // <Buffer rr rr rr rr rr>
