Advanced tools
Provides a way to encrypt and securely store key–value pairs locally on the device.
The expo-secure-store package provides a way to securely store key-value pairs in a device's secure storage. This is useful for storing sensitive information such as authentication tokens, user preferences, and other confidential data.
Storing a value
This feature allows you to store a key-value pair securely. The `setItemAsync` method takes a key and a value as arguments and stores them in the secure storage.
import * as SecureStore from 'expo-secure-store';
async function save(key, value) {
await SecureStore.setItemAsync(key, value);
}Retrieving a value
This feature allows you to retrieve a value stored under a specific key. The `getItemAsync` method takes a key as an argument and returns the corresponding value.
import * as SecureStore from 'expo-secure-store';
async function getValueFor(key) {
let result = await SecureStore.getItemAsync(key);
if (result) {
console.log("🔐 Here's your value 🔐 \n" + result);
} else {
console.log('No value stored under that key.');
}
}Deleting a value
This feature allows you to delete a key-value pair from the secure storage. The `deleteItemAsync` method takes a key as an argument and removes the corresponding key-value pair from the storage.
import * as SecureStore from 'expo-secure-store';
async function deleteValueFor(key) {
await SecureStore.deleteItemAsync(key);
}The react-native-keychain package provides similar functionality for securely storing key-value pairs. It supports both iOS and Android and offers additional features such as biometric authentication. Compared to expo-secure-store, react-native-keychain provides more advanced security options but may require more setup.
The redux-persist-sensitive-storage package is designed to work with redux-persist to securely store sensitive data. It uses the device's secure storage mechanisms and is a good option if you are already using Redux for state management. Compared to expo-secure-store, it integrates more seamlessly with Redux but is less general-purpose.
The secure-store package is another option for securely storing key-value pairs. It is lightweight and easy to use, making it a good alternative to expo-secure-store for simple use cases. However, it may not offer as many features or as much flexibility as expo-secure-store.
