mosip-react-native-secure-keystore v0.1.1

react-native-secure-keystore

A React Native module to create and store keys in android hardware keystore and helps to do encryption, decryption, hmac calculation.

note: This library only supported for android.

Installation

npm install react-native-secure-keystore

Usage

1. for RSA based Key Pair

import SecureKeyStore  from "react-native-secure-keystore";

// ...

if(!SecureKeyStore.deviceSupportsHardware) {
  return
}

const alias = "1234ab";
const data = "any data";

const publicKey = await SecureKeyStore.generateKeyPair(alias);

const signature = await SecureKeyStore.sign(alias, data)

2. for symmetric key

import SecureKeyStore  from "react-native-secure-keystore";

// ...

if(!SecureKeyStore.deviceSupportsHardware) {
  return
}

const alias = "1234ab";
const data = "any data";

await SecureKeyStore.generateKey(alias);

const encryptedData = await SecureKeyStore.encryptData(alias, data)
const decryptedData = await SecureKeyStore.decryptData(alias, encryptedData)

API documentation

deviceSupportsHardware

deviceSupportsHardware() => boolean

Check if the device supports hardware key store

generateKey

generateKey(alias: string) => void

generates a symmetric key for encryption and decryption

generateKeyPair

generateKey(alias: string) => string

generates a asymmetric RSA key Pair for signing

encryptData

encryptData(alias: string, data: string) => string

Encrypts the given data using the key that is assigned to the alias. Returns back encrypted data as a string

decryptData

decryptData(alias: string, encryptionText: string) => string

Decrypts the given encryptionText using the key that is assigned to the alias. Returns back the data as a string

sign

sign(alias: string, data: string) => string

Create a signature for the given data using the key that is assigned to the alias. Returns back the signature as a string

hasAlias

hasAlias(alias: string) => boolean

Check if the given alias is present in the key store
