jovi

Encrypt and decrypt data with AES-256-CTR

Install

$ npm install --save jovi

Usage

const crypto = require('crypto');
const jovi = require('jovi');

const key = crypto.randomBytes(32);

const result = jovi.encrypt('unicorns', key)
/*
{
	iv: <Buffer 50 0b 19 ad 0e 7a 0f 8b 5d 62 c1 b6 8f 5e 08 cb>,
	hash: <Buffer da c7 2a 1b 4d 44 fc ec>
}
*/

jovi.decrypt(result.hash, key, result.iv);
//=> 'unicorns'

API

jovi.encrypt(data, key)

data

Type: buffer, string

Buffer you want to encrypt.

While strings are supported you should prefer buffers as they're faster to hash. Though if you already have a string you should not convert it to a buffer.

key

Type: buffer

Key to encrypt the data with.

jovi.decrypt(data, key, iv)

data

Type: buffer

Buffer you want to decrypt.
