• Android minSdkVersion is now 23 (Android 6.0 Marshmallow)
• iOS module redeveloped using Swift and updated APIs.
• Comprehensive renaming and expansion of APIs.
• Modifications to the return types of some APIs.
• Added clear for comprehensive data clearance.
• Introduced getAllKeys for retrieving all stored keys.

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

Key	Platform	Description	Default
accessible	iOS only	This indicates when a keychain item is accessible, see possible values in Keychain.ACCESSIBLE.	Keychain.ACCESSIBLE.WHEN_UNLOCKED

Keychain.ACCESSIBLE enum

Key	Description
WHEN_UNLOCKED	The data in the keychain item can be accessed only while the device is unlocked by the user.
AFTER_FIRST_UNLOCK	The data in the keychain item cannot be accessed after a restart until the device has been unlocked once by the user.
ALWAYS	The data in the keychain item can always be accessed regardless of whether the device is locked.
WHEN_PASSCODE_SET_THIS_DEVICE_ONLY	The data in the keychain can only be accessed when the device is unlocked. Only available if a passcode is set on the device. Items with this attribute never migrate to a new device.
WHEN_UNLOCKED_THIS_DEVICE_ONLY	The data in the keychain item can be accessed only while the device is unlocked by the user. Items with this attribute do not migrate to a new device.
AFTER_FIRST_UNLOCK_THIS_DEVICE_ONLY	The data in the keychain item cannot be accessed after a restart until the device has been unlocked once by the user. Items with this attribute never migrate to a new device.
ALWAYS_THIS_DEVICE_ONLY	The data in the keychain item can always be accessed regardless of whether the device is locked. Items with this attribute never migrate to a new device.

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.
