react-native-argon2

React Native Wrapper around native Argon2 implementations:

iOS: CatCrypto

Android: argon2kt

Getting started

npm install react-native-argon2 --save

Compatibility Table

React Native Version	Package Version
0.60 - 0.63.2	~0.1.0
0.63.3	^1.0.0

Usage

import argon2 from 'react-native-argon2';
const password = 'password';
const salt = '1234567891011121314151617181920212223242526272829303132333435363';
const result = await argon2(password, salt, {});
const { rawHash, encodedHash } = result;
// rawHash: 031d6c82ddede1200f4794605052745dd562bd4db358e23dac1b11c052eff8d9
// encodedHash: $argon2id$v=19$m=32768,t=2,p=1$MTIzNDU2Nzg5MTAxMTEyMTMxNDE1MTYxNzE4MTkyMDIxMjIyMzI0MjUyNjI3MjgyOTMwMzEzMjMzMzQzNTM2Mw$Ax1sgt3t4SAPR5RgUFJ0XdVivU2zWOI9rBsRwFLv+Nk

Input

The package takes in the following variables:

Parameter	Type
password	string
salt	string
config	object
config.iterations	integer
config.memory	integer
config.parallelism	integer
config.hashLength	integer
config.mode	string

You are not required to configure the third parameter which is the config object, however you do have to provide an empty object to it if you are not changing any of the values. You can set config values with the following example:

const result = await argon2(
    password,
    salt,
    {
      iterations: 5,
      memory: 16 * 1024,
      parallelism: 2,
      hashLength: 20,
      mode: 'argon2i'
    }
);

Output

rawHash is the hexadecimal representation

encodedHash is the string representation
