react-native-argon2

React Native Wrapper around native Argon2 implementations:

iOS: CatCrypto

Android: argon2kt

Getting started

npm install @sphereon/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 '@sphereon/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
