🔐 Secure Property Storage

Helps you define secure storages for your properties using Swift property wrappers.

🌟 Features

All keys are hashed using SHA512 and all values are encrypted using AES-GCM to keep user information safe, automagically. Symmetric key and nonce, are stored in Keychain in a totally secure way.

@UserDefault

This property wrapper will store your property in UserDefaults using StoreKey (any String but i recommend you a String typed enum).

@UserDefault(<#StoreKey#>) var yourProperty: YourType?

UserDefaultsStorage is also available, a subclass of UserDefaults with all the security provided by this library.

@Keychain

This property wrapper will store your property in Keychain using StoreKey.

@Keychain(<#StoreKey#>) var yourProperty: YourType?

As UserDefaultsStorage, KeychainStorage is also available.

@Singleton

This property wrapper will store your property in a memory singleton, every property with the same wrapper and key can access or modify the value from wherever it is.

@Singleton(<#StoreKey#>) var yourProperty: YourType?

As KeychainStorage, SingletonStorage is also available.

@Store

This is a custom wrapper, you can define your own Storage protocol implementation.

@Store(<#Storage#>, <#StoreKey#>) var yourProperty: YourType?

As SingletonStorage, DelegatedStorage is also available with all the magic of this library.
