API

• setItem
• getItem
• removeItem
• exists
• getAllKeys
• clear
• multiSet
• multiGet
• multiRemove

setItem

To set the item, you need to pass the key and value as parameters. You can also pass the options as a third parameter. If the key exists, the value will be updated, otherwise, it will be created. You can use the exists method to check if the key exists. You can also pass the accessible option to set the accessibility of the keychain item (only for IOS).

import RNSecureStorage, {ACCESSIBLE} from 'rn-secure-storage';

RNSecureStorage.setItem("key", "value", {accessible: ACCESSIBLE.WHEN_UNLOCKED}).then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

getItem

To get the item, you need to pass the key as a parameter. If the key exists, the value will be returned, otherwise, it will return an error.

RNSecureStorage.getItem("key").then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

removeItem

To remove the item, you need to pass the key as a parameter. If the key exists, the value will be removed, otherwise, it will return an error.

RNSecureStorage.removeItem("key").then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

exists

To check if the item exists, you need to pass the key as a parameter. If the key exists it will return true, otherwise, it will return false. Mostly you don't need to use this method because getItem will return an error if the key doesn't exist. But for performance you can just check if the key exists before calling getItem.

RNSecureStorage.exist("key").then((res) => {
	console.log(res ? "exists" : "does not exist");
}).catch((err) => {
	console.log(err);
});

getAllKeys

To get all keys, you need to call getAllKeys method. It will return an array of keys.

RNSecureStorage.getAllKeys().then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

clear

To clear all data, you need to call clear method. It will return true if the operation is successful. Otherwise, it will return remaining keys.

RNSecureStorage.clear().then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

multiSet

Multi set is a new feature that allows you to set multiple values simultaneously. You need to pass an object as the first parameter

import RNSecureStorage, {ACCESSIBLE} from 'rn-secure-storage';

const items = {"key_1": "multi key 1", "key_2": "multi key 2"};
RNSecureStorage.multiSet(items, {accessible: ACCESSIBLE.WHEN_UNLOCKED}).then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

multiGet

With multi get you can fetch multiple values at once. You need to pass an array of keys as the first parameter.

RNSecureStorage.multiGet(["key_1", "key_2"]).then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

multiRemove

With multi remove you can delete multiple values at once. You need to pass an array of keys as the first parameter. If your keys are removed/not found, it will return an array of keys that are not removed/found.

RNSecureStorage.multiRemove(["key_1", "key_2"]).then((res) => {
	console.log(res);
}).catch((err) => {
	console.log(err);
});

Options

Keychain.ACCESSIBLE enum

I need your reviews

I have rewritten the Android module with enhanced security features. I need your reviews. Please test the new version and let me know your thoughts. I will be happy to hear your suggestions and comments. I'm planning to release the new version to handle biometric authentication on Android.

Disclaimer

As an open-source enthusiast and developer, I originally created this library for professional use. However, with recent changes in my career, my focus has shifted away from React Native, limiting my involvement to personal projects. Consequently, my time to address issues and review pull requests for this library has become restricted. I remain committed to maintaining and improving this library, but my response times might be longer. I greatly appreciate your patience and understanding.

The beauty of open-source is in collaboration. If you find this library useful and would like to contribute, whether through code, addressing issues, or even buying a coffee to show support, it would be immensely appreciated. Together, we can ensure the continued development and enhancement of this library.
