Random Bits Generators\n\nBased on NIST Recommended DRBG from [NIST SP800-90A](https://en.wikipedia.org/wiki/NIST_SP_800-90A) with the following properties:\n * CTR DRBG with DF with AES-128, AES-192, AES-256 cores see [issue #1](https://github.com/cryptocoinjs/drbg.js/issues/1)\n * Hash DRBG with DF with SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 cores\n * HMAC DRBG with SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 cores\n * with and without prediction resistance\n\n## Installation\n\n```shell\nnpm install drbg.js\n```\n\n## Usage\n\n```javascript\nvar drbgs = require('drbg.js') // import HashDRBG and HmacDRBG\nvar HashDRBG = drbgs.HashDRBG // or require('drbg.js/hash')\nvar HmacDRBG = drbgs.HmacDRBG // or require('drbg.js/hmac')\n\nvar drbg2 = new HashDRBG('sha256', entropy, nonce, personalization_data)\ndrbg2.generate(5, additional_data) // \ndrbg2.reseed(entropy, personalization_data)\ndrbg2.generate(5, additional_data) // \n\nvar drbg3 = new HmacDRBG('sha256', entropy, nonce,
