Usage


`javascript
import SecureStorage, { ACCESS_CONTROL, ACCESSIBLE, AUTHENTICATION_TYPE } from 'react-native-secure-storage'

async() => {
const config = {
accessControl: ACCESS_CONTROL.BIOMETRY_ANY_OR_DEVICE_PASSCODE,
accessible: ACCESSIBLE.WHEN_UNLOCKED,
authenticationPrompt: 'auth with yourself',
service: 'example',
authenticateType: AUTHENTICATION_TYPE.BIOMETRICS,
}
const key = 'someKey'
await SecureStorage.setItem(key, 'some value', config)
const got = await SecureStorage.getItem(key, config)
console.log(got)
}
`

This library has now implemented getItem, setItem, removeItem and getAllKeys methods of AsyncStorage from React Native. It doesn't support callback and replaced the callback param with an option param.

In addition, this library has a getSupportedBiometryType() method which Returns one of BIOMETRY_TYPE indicating which biometry type the device supports, and a canCheckAuthentication([{ authenticationType }]) method which checks whether the specified authenticationType is available.
